Best Car Battery Charger - Top 5 Reviews and Things To Know


Despite the tremendous advances that were made in the automotive industry, car batteries seem to be as unpredictable as ever. Even with diligent and careful maintenance, you never truly know when your battery will give out. Even worse, a dead battery can leave you stranded in a remote location or cause you to be late for your work. To help prepare you for this situation, we are going to help you pick the best car battery charger on the market today.

The factors that you should consider before buying a car battery charger

Before committing to any particular model, you need to familiarize yourself with the basic characteristics and features of these devices. This will help you make a smart decision purchase decision and ensure that you are getting something that suits your needs and lives up to your expectations. Below is a brief overview of some of the main factors that you should keep in mind when you are in the market for a new car battery charger.


This is the first thing that you should pay attention to when you are looking for a new car battery charger. Each type of battery requires a specific type of charger, so if you don’t take the time to check the cells of your car battery, you run the risk of buying a charger that is not compatible with it. The most common types are white cell, AGM cell, jell cell, and VRLA cell. The voltage is another variable that you should factor in. Whether your battery is rated at 6 volts or 12 volts, you need to make sure that the charger is capable of handling it.

The ampere rating

Most affordable chargers have an ampere rating between 10 and 20 amps. This might be sufficient for a small car battery, but we would generally recommend you to top for something above 55 amps. These mid-range chargers are quite versatile and are able to tackle the vast majority of batteries on the market. If you want a charger for professional use, you should aim for models that boast a minimum of 60 amps.

The safety features

Safety features are invaluable when it comes to chargers. Regardless of the quality of the unit, there are several risks that are inherent in their mode of operation. To eliminate these potential issues, you should always opt for a charger that is safeguarded against overload, over-current, over-charging, and over-voltage.

Trickle charge

This also referred to as float mode. Trickle charging is essentially charging a battery at a rate that is identical to its discharge rate. This is extremely valuable due to the fact that it allows the battery to maintain a full charge without being affected by overcharging.
