The best car battery charger buying guide

The best car battery charger buying guideThere are plenty of options on the market when it comes to the car battery charger, but not all of them will work well with your needs. This is why you need to be careful in choosing a brand and model before buying.

For instance, you need to figure out whether you want a simple solution that easily jumpstarts your battery, or you want something that can maintain it, or something even more complex than that. You also need to consider what sorts of features you want from your car battery charger, not to mention set a budget that works for you.

Battery and charger type

Different vehicles use different types of batteries. For example, most cars have lead acid batteries, and RVs typically use deep-cycle batteries. It’s important to know what kind of battery your vehicle has so you can buy a compatible battery charger.

Speaking of battery chargers, they also come in many different types with varying capabilities. To help you understand, we’ll talk about each of these types below:


The first is a basic car battery charger that has the sole function of restoring the juice of your car battery in the event of a close or total discharge. There are plenty of options on the market for this type of battery charger, and in various sizes, shapes, and amperages you need for your car’s battery.


There are also battery maintainers, which technically don’t jump start your battery. Rather, they prevent a complete discharge from happening in the first place by maintaining your battery’s juice. Battery maintainers are great for, well, general battery maintenance, as well as quick fill ups, as long as you use them regularly.


Finally, you will also find a few battery restorers, which serve the purpose of breathing new life into an old battery by breaking down various contaminants that have built up inside the battery’s cells, therefore enabling it to hold a charge again. That said, battery restorers are expensive and are mostly reserved for professional applications.

Manual vs automatic charger

Battery chargers can also be manual or fully automatic. On one hand, manual chargers are ideal for reviving your dead battery, but on the other hand, automatic chargers are a lot easier to use and can even regulate the charging process so your battery doesn’t suffer from damage caused by overcharging.

Power requirement

You will find that battery chargers offer differing power capacities. Lower capacity chargers are great for slow charges and maintaining the battery over time, whereas high capacity chargers are a must for doing jump starts and for fast charging capabilities.

Battery charger size

Generally speaking, the larger the battery charger, the more power it offers. However, this also means that it can be a bit difficult to use, not to mention find a suitable space inside your vehicle. This is why many drivers prefer more portable options.


Now, battery chargers aren’t really all that expensive, but you’ll still want to consider how much you want to spend on one. Aside from the brand, the power capacity and relevant safety and convenient features that a battery charger offers also directly affect its price. So, if you want a better, higher power, and more reliable charger, prepare to spend a bit more.

Final Thoughts

It’s not only a convenience, but a necessity, to have a means of charging your flat battery when you’re out on the road, so you don’t have to deal with a car that just won’t start while you’re stuck in the cold or hot outdoors. Car battery chargers not only give you your needed jump start, but can also maintain your battery so a complete discharge never happens again.

The best car battery charger for us is the Clore Automotive Jump-N-Carry JNC660 1700 Peak Amp 12 Volt Jump Starter, which is a high powered, feature packed, technologically advanced, durable, and long lasting car battery charger that is well worth your money.
