battery charger for car Buyer’s Guide
Battery Tender 12V Battery Charger
This is a battery charger that has been designed with a spark proof when you have a lead connection on. Never worry at all about the any damage being caused to you battery because there is reverse polarity that has been installed in the system that will ensure that you are always protected. If you have a lead battery acid that is up to 12-V, then this is the best time that you need to purchase this charger.
It is a charger that has been designed with a 4-step complete charging program that will allow you to have optimization of your battery without having the fear of doing any overcharge. The charge cycle I also automatically controlled and switches to float mode when the battery has been fully charged to maintain the charge and protect the battery from spoiling.
Deltran Battery Tender Battery Charger
This charger has the best ability to make sure that you battery is well charged and that is why it is called the Battery Tender. It will switch automatically to float charging mode when it senses that your battery has been fully charged. When it has fully charged the battery that you are using, it will go ahead and ensure that it is able to maintain at a proper storage until you decide to use it.
This charger cannot be rated with others because will charger faster than any other 3-amp charger that is out there. It has been design in such a manner that it is temperature compensated so that you have that temperature compensation so that you get optimum charge voltage. There is a connect harness that comes with the system and can be used in hard to reach areas.
Be confidence in your charging and that is why we need you to have our chargers with you. You will have your batteries maintained and even preserved when charging voltage has been reached. It is hard to get a charger that will disconnect from charging a battery and go to maintain it at that voltage until you take it off to go and use it. Get yourself one and you will have solved all your charging problems.
The reason that those old-style chargers boil the electrolytes in a typical flooded battery is because they don’t shut off when the battery has reached capacity. This can be controlled through several methods. Solid state controls use resistors and capacitors to measure the voltage on the battery. These work, but they can fail, leaving your battery melted inside your car.
A microprocessor is essentially a computer for you battery charger. Where a solid-state charger puts amperage to the battery until it shuts off, the smart charger operates in a much different manner. Rather than simply blasting the voltage charge to the battery, the smart charger utilizes a multi-phase charging cycle similar to what the alternator does in the car. Pro-Logix smart chargers from SOLAR use a 7-phase cycle to achieve maximum charging efficiency.
The last thing you want to do is waste time charging a battery with a bad cell inside. The Pro-Logix chargers from SOLAR have internal testing mechanisms that check the batter for bad cells, sulfation (this is what happens when a battery is used when not fully charged), or deeply discharged batteries.
Deeply discharged batteries must be charged slower than a mildly-discharged battery in order to achieve full charge. “Deeply discharged” is considered having less than volts or lower than 50% of its capacity. If a battery is so discharged that it has below volts, some battery chargers won’t even recognize that a battery is connected and a second battery must be connected to get the charger to cycle.
Unlike a solid-state charger, the smart charger is also the perfect solution for long-term storage. Over time, batteries will lose their charge naturally. With a maintenance charger connected, the battery will remain fresh during storage so that when it is time to ride, the battery is good to go.
How to choose a charger
You know you need a high-quality battery charger, but you don’t know which one to choose. We have broken them down into several categories that will help you decide exactly what you need. All of the Pro-Logix chargers are capable of charging all types of batteries and each one has the 7-phase maintenance cycle to ensure that the battery it is connected to lasts as long as possible.
For the casual user, the entry-level charger will be sufficient. These are available in and 20-amp versions.
Casual Battery Charger User
The casual user is defined as owning 1-vehicles, living in a moderate climate, where both vehicles are driven daily. Driving your car every day helps maintain the battery, which reduces the need for regular use of a battery charger. The Pro-Logix PL23or PL2320 are perfect for the casual user to provide a maintenance charge for vehicles, personal watercraft, ATVs, and battery-powered lawn equipment when needed. The PL23has 2, 6, and 10-amp charge modes, where the PL2320 steps up the amperage to 20 amps for a faster charge, perfect for larger batteries and heavy-duty batteries such as lawn equipment and PWC/ATVs where you need a full battery in relatively short charge time.
If you have ever needed to get your vehicle started with a discharged battery, then an upgraded charger with Boost Mode is the one for you.
Professional Battery Charger User
If you run a shop or just own a lot of vehicles that use batteries, then you might want to consider a wheeled charger, such as the Pro-Logix PL3730. This charger features 5, 15, 40, and 60 amps in standard charge mode, with a 275-amp boost mode for starting vehicles with completely discharged batteries.
The Pro-Logix PL2520 experience
First, the battery was tested with a voltmeter. 11.7volts at rest, but there was no enough energy stored to crank the engine.
The PL2520 was connected and it recognized the battery and showed the current charge on the display.
The PL2520 has multiple settings for boost mode, voltage and amperage, as well as battery type.
You can choose several variables for the charging rate, voltage and battery type. We put the charger into 10-amp, 12-volt, Standard battery configuration as we had time for an overnight charge. If we needed the battery quickly, 20-amp would be faster, and boost mode would start the car, but this battery needed a full charging cycle as the alternator needs replaced in the car.
The completed battery shows 13.0volts.
The battery was disconnected from the charger and left to rest for an hour to check the residual charge. The voltmeter showed a full 13.0volts resting voltage, and the car has not had any issues starting for week without any additional charging for our tests. After the one-week, the battery has been connected to the charger nightly.
The alternator in the car needs to be replaced, as it is only charging part of the time. This is where a smart charger is very handy. The battery can be connected each night to ensure that the battery stays charged until the alternator can be replaced. Many modern cars use alternator locations that make it extremely difficult to change them, and the car is often down for a long time. This particular vehicle, a 2000 Mercury Cougar, is one of those vehicles. Until the alternator can be replaced, the Pro-Logix Charger will keep the battery from being deeply discharged and ruined, and allow the owner to continue driving it to work. If you have a long commute, this is not a good solution, but if you only have to drive 30 miles a day, it is good stop-gap alternative.
Schumacher SC-1200A-CA Speed Charge is a 6V/12V 1Amp fully automatic microprocessor controlled battery charger for premium charging applications? With 6V/12V auto voltage detection, this charger can do Amp for maintaining, Amp for medium charging and 1Amp rapid charging, with a digital display. Also has reverse hook-up protection so the unit will not operate if clamps are reversed, and float mode monitoring. Energy efficient and eco-friendly.

Selecting the Right Amperage
Charging ports on battery packs, like charging ports on wall-warts and computers, can provide electricity at two amperage rates: 1A and 2.1A. All USB devices can use both ports, but if a device can only handle 1A of power then it will automatically limit itself to 1A on a 2.1A port and if a 2.1A device is on a 1A port it will also charge (but at a much slower rate). Both of our test devices feature a 1A and a 2.1A port.

Welcome to our website – we’re glad you stopped by! If you arrived here from a search engine or a link from a forum, we’d like to invite you to take a look around the rest of our site after you learn all about LiPo batteries. At the end of the article, we’ll have some links to other articles and reviews you may find interesting. But above all, please share this guide with anyone you know that needs help with their LiPo batteries. The more everyone knows, the safer the hobby can become – and that’s good news for everyone.
You can also buy car batteries from local service stations and tune-up shops; however, the selection is limited and the stocks may not be fresh.
Difference between CCA and CA
CCA (cold-cranking amps) – indicate how much electrical power the car battery can deliver to the car’s starter engine, at zero degree Fahrenheit.
CA (cranking amps) – This is another measure of electric current in the battery, taken at 3degrees Fahrenheit or at freezing point. When seen on battery case or label, the CA rating is usually higher than the CCA rating.
If you’re looking for the easiest option for keeping your rechargeable batteries full, we recommend the Panasonic Advanced Individual NiMH Battery Charger, which comes with four Eneloop batteries. This simple device doesn’t require any setup and starts charging your batteries accurately as soon as you plug them in. It can charge a single battery (AA or AAA) if need be, unlike some comparable units, which require at least two batteries to work properly.
The BC-700 displays the status of each battery position on a small LCD and allows you to independently select between three charging speeds.
The Lacrosse BC-700 will help anyone that wants to actively manage their batteries squeeze out every drop of power without adding superfluous features and breaking the bank like the top-of-the-line Powerex WizardOne—but it still costs about twice as much as the Panasonic charger. The BC-700 is based on the same pulsed charging and Negative Delta V detection as the Panasonic above, so you know it’s an accurate, automatic charger. But while the Eneloop charger does everything behind the scenes, the BC-700 displays the status of each battery position on a small LCD and allows you to independently select between three charging speeds as well as a variety of testing and maintenance modes. For most people, the repeated button presses needed to sort through these features will just make rechargeable batteries seem like a chore, but the work can help eke out slightly longer lives and marginally increased capacity if you’re willing to invest the time.
Smart chargers with room for more than four batteries are hard to find, but if you need the extra space, we recommend the Powerex MH-C800S, which can charge any combination of eight AAs and AAAs at a time. If you use a lot of batteries, the Powerex MH-C800S is worth paying extra for. But you should only get it if you really need all eight charging slots from one outlet, since it typically costs about twice as much as the Panasonic.
Unlike the Lacrosse BC-700, the MH-C800S only offers two charging speeds and displays a simple three-bar battery gauge instead of detailed charging information. Plus, it costs around twice the price as our simple pick from Panasonic. We also don’t like that the charger defaults to the faster 1-A charging mode, but a clearly labeled “Soft” button will slow that down to a 500-mA rate, which you should do every time to maximize the number of recharges your batteries can take.
We passed over the Powerex/Maha Energy MH-C9000 WizardOne Charger-Analyzer. It’s a feature-packed tinkerer’s dream, allowing you to select charge rates up to 2,000 mA at 100-mA increments, and it combines charge and discharge speeds for testing and conditioning—which is why we used it for our own testing for our upcoming rechargeable AA batteries guide. Its display is larger than the Lacrosse units, but it also requires longer button sequences to display info or set up charging profiles. So while it can do more, it also takes longer to do the things you’d normally want to do. Plenty of users swear by this charger, and even those that don’t will admit it’s extremely capable. For most people, though, the extra cost is going to net them extra frustration instead of extra practical features.
Lacrosse also makes a higher-end and lower-end charger in addition to the BC-700, but neither strike us as good a balance of value and usability. The smaller, less expensive BC-500 has a less intuitive one-button interface, doesn’t show as much information, and most importantly, doesn’t have selectable charging currents, instead sticking with 500 mA–the high end of what most experts recommend. Aside from included accessories, the biggest feature gained from moving up to the higher end BC-1000 is incredibly high speed charging. It allows for 1-A charging across all positions, as well as 1.5- and 1.8-A charging for two batteries—all settings we strongly recommend against using since doing so will significantly lower the number of recharges your battery can take.
The Maximal Power FC9Universal Rapid Charger is a large unit that will charge not only NiMH batteries, but also Nickel Cadmium (Ni-CD), Rechargeable Alkaline Manganese (RAM), and (the manufacturer claims) some non-rechargeable alkalines. (This last use is not generally recommended for safety reasons.) Even setting that aside, it offers some of the same control features as our Lacrosse BC-700 pick but with less information monitoring. The Lacrosse is the smaller, more reliable choice.
Like the Maximal unit, the Xtar VCcharges more than just NiMH batteries, also recharging Li-ion 18650 style batteries. These types of rechargeable Li-ion batteries are different from their disposable AA lithium replacements because they have higher voltages required by specific gear, most often camera equipment, and can destroy low voltage gear expecting AA power. The VChas a clear display, multi-stage charging, and selectable current levels. But it doesn’t offer the capacity discharge and recharge test of our Lacrosse pick, and even with a decently powerful USB power supply, some users report power bottlenecks.
Based on specifications, the Foxnovo F-4S is a competent multi-current charger but has a slower, single-button interface to cycle through all the modes. Many users complained about how loud the alert is every time the device finishes a function. No one wants to be woken up at a.m. because their batteries are ready.
Both the Poweradd 903A 4-bay High-Speed Intelligent Battery Charger and the EasyAcc 4-slot AA AAA Battery Charger (now discontinued) are inexpensive and seem as simple as our top pick. But the good user reviews are mostly courtesy of free samples, and we’re not as sure of charging technique and internal logic as we are our pick from Panasonic. If we get more hands-on time, we’ll take a closer look.
The Avalon Battery Charger With Ultra-speed Technology looks and is priced similarly to our pick, but most of the positive reviews we’ve seen have been written in exchange for sample products.
One of the leading advantages of AGM deep cycle batteries is these batteries can be charged times faster than flooded deep cycle batteries of the same amp-hour rating. AGM batteries are the most common battery type used in marine applications.
However, unlike flooded batteries, AGM batteries are sensitive to overcharging and they also do not like heat. Therefore, if your deep cycle battery is AGM, choosing the best charger would be a bit more complicated.
A charge to 2.40V/cell (and higher) is fine. However, the float charge should be reduced to between 2.2and 2.30V/cell (summer temperatures may require lower voltages). A battery charger that is dedicated to charging 12V flooded lead acid often have a fixed float voltage setting of 14.40V (2.40V/cell), using it could overcharge the AGM battery.
To protect and maximize the life of your AGM battery, you should select a multi-stage charger that has a setting for AGM. And because AGM batteries can be fully charged very quickly, we would highly recommend that you buy a charger that has max charge current less than 25Ah.
This Optima’s battery charger features many built-in technologies and microprocessors which enhance the performance of 12V AGM batteries, recovers deeply discharged batteries and helps extend battery life. And if you already have an Optima’s marine battery, this charger is probably the best choice.
Charging Gel Deep Cycle Batteries
Gel batteries actually predated the AGM type but are losing market share to the AGM’s. But Gel batteries are still quite common in solar storage systems.
Gel batteries tend to have VERY NARROW charging profiles and can be damaged easily by charging them inappropriately. If you have a Gel battery, do not charge it with a conventional car battery charger. There are several methods for charging gel batteries, however, constant voltage charging is the best way. For this type of charging, a fixed, regulated voltage source is used to charge the battery.
BatteryMINDer 12V 2/4/Amp Wet/Gel/AGM Battery Charger will satisfy you.
Charging Lithium-ion Deep Cycle Batteries
Lithium-ion batteries cannot absorb overcharge. When fully charged, the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium and compromise safety. They should also operate safely within the designated operating voltages as the battery becomes unstable if inadvertently charged to a higher than specified voltage.
For better battery life and performance, choose a charger that has a setting for lithium. And because all lithium-based batteries are safer at a lower charge, you should consider a model that has a low amp-hour rating (20Ah or less). This is a very good choice.
Charging Your Deep Cycle Battery with a Generator
Using a generator is the fastest way to charge your deep cycle battery during the power outage or when you need to charge deep cycle batteries in your RV as fast as possible. Most inverter generators have a 12V DC output built into them, however, trying to charge a battery using this is almost a waste of time. The 12V DC output is usually limited to around amps, the voltage can fluctuate and is not suited to effectively charge your deep cycle battery.
The best way to charge your deep cycle battery with a generator is to connect a Smart Charger to the 120V AC outlet of the generator. A smart charger uses or more stages to charge the battery bank exactly the way it wants to be charged depending on its state.
Xantrex TRUECharge12V (20A, 40A, 60A) Battery Chargers. These are some of the best deep cycle battery chargers on the market. They are best suited for charging with a generator as they feature low electrical interference and can protect your deep cycle battery against voltage fluctuations and unexpected shutdown.
Charging Your Deep Cycle Battery with Solar Panels
We have discussed the best chargers for solar batteries in our previous guide to choosing the best deep cycle battery for solar power systems. But here are some basic terms that you should know about charging your deep cycle battery with solar panels.
In solar power systems, the batteries cannot be charged without a Solar Charge Controller. A solar charge controller manages the power going into the battery bank from solar panels. It ensures that the deep cycle batteries are not overcharged during the day, and that the power doesn’t run backwards to the solar panels overnight and drain the batteries.
CTEK D250S Dual is a 5-step charger. This is a smart deep cycle battery charger which is designed to obtain energy from DC sources such as alternators, solar panels or wind power and optimises this power to meet the charging requirements of different battery banks.
Maximum Power Point Tracker ) that helps the solar cells produce power as efficiently as possible by taking the most efficient source of energy from the solar panels automatically, and then using the power to charge the battery.
Charging Deep Cycle Battery While On the Water
You’ve been looking around for a way to help pump some juice from the outboard alternator and deliver it to your trolling batteries to extend run times, decrease on-shore charge times and increase battery life. If so these are things you should know.

Most deep cycle battery systems that we have is 12V. 1volts is simplest and most standard, used in cars, RVs, trolling motors and boats. If you want a small simple power system, 1volts will probably be easiest. But in some applications such as marine or home solar energy systems, where we often build large battery banks that store hundreds or even thousands amp-hours, the 24V or 36V or 48V system has some technical advantages over the 12V system.
Depending on which car you go for, you need to be aware of the different charging options open to you. All models will have a charging cable with a standard UK three-pin plug available, so you can simply plug the car into the mains. But this is the slowest way of charging an EV.
What to look for
The biggest issue with electric cars, and particularly used electric cars, is how well the batteries keep their charge. If you purchase a car that has trouble maintaining battery energy, then you’ll need to consider the cost of replacing the battery. This can be astronomical, especially when compared to the cost of buying a used EV, as electric cars have poor depreciation that will soon see their used price fall below the cost of battery replacement.
To eliminate this potential headache, you can look at an EV that has a battery lease plan to go with it. Renault offered such a scheme from 201onwards, and while you’ll have a monthly battery lease to pay, this will be offset by the car’s lower price.
Other than that, you can look at a used EV in the same way as you would a conventional car. Make sure all of the electrics work – EVs are usually pretty well equipped, so check all the gadgets are functioning – while most electric cars will have been used in town, so keep an eye out for wheel damage that may extend to the suspension behind it.
Likewise, a small, portable generator with either 240v or 12v power outlets will quite happily keep your portable fridge powered for as long as your generator lasts, and can likewise double as a source for recharging your battery.
Charging Your Battery
So you’ve got your fridge, you’ve got your battery and battery pack, what’s next? The last thing you’ll need is some means of recharging your battery, and for this, you have a few options.
The standard method for recharging a battery is known as ‘Direct Charging’, or ‘Trickle Charging’. This involves connecting your battery directly to some sort of power source (such as the ones outlined below), and will deliver a constant stream of power through to your battery. However, this is also the most inefficient means of recharging your battery, and can even be potentially damaging.
For starters, delivering a constant stream of power takes an incredibly long time to charge the battery. Next, it will also never completely fill a battery to 100% charge, usually coming up at around 80%. Lastly, direct charging means the power will continue to stream into your battery, even after it’s reached its maximum level, unless you manually turn it off. Continuing to charge a full battery will damage it if left for too long.
The other option is ‘Smart Charging’. By placing a Smart Charger between your battery and the power source, the charger will use an efficient stage process to charge your battery, delivering a full charge in a far shorter amount of time than direct charging. Smart charging will also recharge your battery right up to 100%, and when it reaches that point, it will automatically shut off, so there’s no chance of causing damage from overcharging. Most Battery Packs/Boxes come with a Smart Charging system built in as standard, or you can purchase one as a separate unit.
It’s important to note that you do not actually have to disconnect your battery from your portable fridge while recharging, meaning your fridge will stay powered right throughout the charging process.
Here in our Aussie conditions, one of the most popular methods for charging your battery on the road are portable solar panels. They’re light, easy to transport, and can easily recharge your battery in a matter of hours. When purchasing a Solar Panel Kit, they also come with a ‘regulator’ unit, which converts that solar power into energy usable by your battery. When your battery starts to run low, simply put your solar panels out in the sun, plug them into your battery pack, and let the sunshine do the rest.
Solar panels are measured in Watts (W), and as with batteries, bigger is better. We recommend using a 120W Solar Panel Kit, which should charge your 120Ah battery back to full in about to hours each day under normal conditions running a standard 40L fridge.
As above, but the cigarette lighter socket continues to power the fridge when the vehicle is turned off. Some vehicles have this option.
