Best Car Battery Charger Buying Guide

You may be wondering what exactly it is about a battery charger that makes it better than the rest? What should you look for in good quality, reliable battery charger? There are certain features about a product that makes it stand out from the rest.

Let’s take a look at them in-depth, so the buying process becomes easier for you:

Safety Features

Even though batteries look harmless, they are a cause of some unfortunate accidents if not handled properly. They contain a high amount of voltage, acid, and gasses. Moreover, you have to be extra careful if you have little knowledge of car batteries.

However, thankfully, car battery chargers are equipped with multiple safety features that ensure maximum safety to the consumer. A popular safety feature is reverse polarity protection. This comes into action if you accidentally connect the battery clamps to the wrong ends.

Furthermore, this action under normal circumstances can not only shock one but also result in a possible explosion. However, the reverse polarity protection feature makes you aware of the wrongly connected cables. Some models won’t allow current to run unless properly plugged in.

Charger Type

Prior to buying a charger, it is important to know its types. So, basically, there are three types of chargers available, and each has its own importance.

  • Trickle chargers

Trickle chargers wok best for completely discharged batteries. Moreover, they will provide a very slow and steady current to your battery to bring it back to life. This process takes about 24 hrs.
However, they are operated manually, which means you will have to unplug it after it is done charging the battery. It might be over charged and potentially damaged otherwise.

  • Solar Chargers

These chargers, as the name suggests, take energy from the sun to charge your battery. However, they are used for more maintenance purposes generally, as they offer very low amperage. Furthermore, these are great to use if you plan on going on a long drive or a camping trip.

  • Fully Automatic Chargers

These types of chargers are the simplest to use. This is because you only have to plug it in and connect it to the right terminal of the battery. They feature modern technology that checks the charging process and improves battery performance.

  • Reliable, Durable & Compatible

A car is more than just a mode of transport for most of us. It carries emotional value as well as costs a lot. Therefore, you wouldn’t want to invest in an unreliable battery charger for your car, as it could potentially damage it. This is why the battery charger you invest in should be from a well-known and reliable brand.
It is important that the product you invest in has a good warranty. This ensures that it turns out to be a long-term investment for you. Furthermore, one of the most important factors of buying a car battery charger is compatibility. You have to ensure that it is compatible with the kind of battery and vehicle you own.

Ease of Use

The product you invest in should be convenient for you. It’s construction and design should work for the situation you care to use it in. If you plan on traveling with it, invest in a charger that is small and portable. Meanwhile, if traveling is not on your list you could buy a heavy unit as well. Furthermore, the proper handling of the product is important, thus opt for a unit with a comfortable handle, etc. Plus, if you are someone who needs to charge more than one battery type, you need a flexible product.


Buying a car battery can be a difficult process as it requires research and time. However, the car battery you invest is important; thus, the extra research always pays off. This post aims to help you find a great car battery charger.

Hopefully, by the time you’ve reached this section of the post you’ll have a better understanding of battery chargers.
Moreover, don’t forget to make sure that the product you choose works for your vehicle. This is because compatibility is key and allows the product to work well under the situation you’ll be using it in. It will save you a lot of future hassles if you invest in a good car battery once.
