Best Car Battery Chargers Review in 2020

Every car owner, no matter how long the experience, can still make some mistakes in usage and maintenance. One usual problem is leaving the headlights on too long and coming back to a car that won’t turn back on. This problem can happen anytime and anywhere.

This is where a car battery charger comes in.

Batteries cannot sustain themselves for too long. They require constant recharging, and they might just give up when they reach their end of life. A car battery charger can help you address problems like this. It has become an essential accessory that you must always have in your car, just like how you look at a spare wheel.

Benefits of A Car Battery Charger

Here are the benefits that you can enjoy if you invest in an automotive battery charger.

You can avoid flat batteries and assure that you have a car that will always start.

A car battery can be easily affected more than you think. Sub-zero temperatures can weaken a car battery, and cold weather can also affect how the car’s alternator can recharge the battery.

By using an automotive battery charger, you can ensure that your battery will always be full, and you will be ready to start your car.

An automotive battery charger is a good investment.

With a flat battery, you will always have to deal with calling roadside assistance, and you probably know by now that this is not really something cheap. Sometimes, the damages also hurt other electric systems in the car, and repairing comes with additional expenses, too.

Fortunately, you can avoid these problems by keeping your battery charged without having to pay someone else.

A car battery charger can protect your car’s settings.

If your car battery gets too drained, it can no longer supply the power for your car’s electrical system. This leads to having to reset everything because it will wipe out all your pre-set preferences and settings. This nightmare can be avoided by having a battery charger inside your car.

Car Battery Charger Buying Guide

Now that you have been shown the best car battery chargers in the market, it is still very much important that you check the different factors that you should know before you shop and get a car battery. Of course, the car battery charger that you must go for must have the best performance, charge efficiently, and help maintain your battery health.

But, of course, with the current technological advancements, it is a good idea to go for a charger with multiple functions. It would be good to get one that also offers battery diagnostics and other features.

Here are the other factors that you should consider:

Manual or Automatic

The earlier models of car chargers are manual, but automatic chargers are also becoming much common these days. This is because they do not require that the drivers keep track of the time spent charging and the charge level. With automatic chargers, it will switch modes when the battery is full to prevent overcharging, therefore, prolonging the battery’s life.


Another important thing to know is the chemical makeup of the battery. You can check if the battery is a deep cycle one or a standard lead-acid battery, then you should check if this is compatible with the battery charger.


A very integral part of making your purchase decision is identifying the different safety features that come with your battery charger. The newest chargers usually offer the following:

  1. Float mode
  2. Battery testing
  3. Clamp amps
  4. Spark proof amps
  5. Reverse polarity alarm


Most car battery chargers that are available on the market draw their power from 12-volt batteries. However, if you consider power, these chargers vary from having 6 amps, 10 amps, or even as high as 20 amps. The higher the amount of amps is, the longer the charger will last, and the quicker it will fill up the car’s battery. But, you should also consider that higher power comes at a higher price.


Another amazing feature that you can go with is the ability to monitor the capacity of the car battery while it is charging and the ability to identify whether the battery is in need of some recharging. If you are looking for the best car battery charger, it should have battery level indicators and a reverse polarity alarm.


Not all drivers on the road are equipped with the technical know-how of car maintenance. This is why it is very important to have an easy to use gadget that can be operated simply and does not come with intense complications.

Another bonus to look for is value-added features like LED lights and USB ports.


As cars do not usually stay too long at a single place, it is important that the battery charger you get is a model that you can easily bring to various places. The ideal model must be able to fit easily in your car’s glove compartment or a small travel bag you can store in your trunk.


What is the best charging rate for a car battery?

A fully running car battery should measure at about 12.6 volts or higher. With the engine is running, it might be measured to be about 13.7 to 14.7 volts. A basic car battery charger at around 2 amps, but it can range from 2 to 10 amps. The higher the charge, the faster you can charge a flat battery.

How many amps is a car battery?

The average car battery has a capacity of 48 amp hours, which means when it is charged fully, it has the capacity to deliver 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours, etc.

How long should I leave the battery charger in the car?

Because the typical maintenance car battery charging uses 2 to 4 amps, it can usually take about 24 hours to be able to charge a dead battery fully.

Are 10 volts enough to start a car?

Unfortunately, there is no exact answer to identify the proper voltage required in starting a car. There are many things that can influence this, including the current situation of the battery and the temperature in the surroundings. In general, a fully charged battery must show 12.6 to 12.7 Volts.

Final Thoughts

Having to choose the correct car battery charger can be a complicated decision, especially with knowing how wide and varied the currently available options in the market are. There are different factors that every car owner must consider, which means there is no specific answer that will fit all kinds.

We hope that you use this guide to help decide on the best car battery charger for you. Being able to have a charger can make you have more options in times of unfortunate incidents and accidents.
