Types Of Car Battery Chargers

If you own a car or are planning to get one, there are many things that you must know about including the type of battery that goes into the car. Here are few of the common types of battery chargers:

  1. Calcium battery: These batteries are lead acid batteries that use calcium in the positive and negative terminals of the battery. The antimony makes use of lead, thereby making it a low-maintenance option. Calcium batteries are observed to be relatively easier to recharge as they don’t need a higher voltage for charging.
  2. Deep-cycle battery: One of the common battery types, they are lead acid batteries that offer a deep discharge value, which means they perform better than most other types of batteries.
  3. Wet-cell battery: These batteries contain a combination of water, lead, and sulfuric acid. These are cheaper than most other batteries but may not offer the conveniences or capacities offered by the modern batteries.
  4. AGM battery: AGM stands for Absorbed Glass Mat. These are similar to flooded types of lead acid batteries but the difference is that the electrolyte is engulfed in mats of glass. Offering higher capacities, they are increasingly being used in modern cars.
  5. EFB battery: It stands for Enhanced Flooded Battery. This is essentially an improvement over older wet or flooded batteries, which means that it offers higher capacity and meets the high energy demands of modern cars. These batteries are also more durable and perform better than traditional cells.

Now that you know the types of batteries in use, let us take a look at the 11 best car battery chargers that you can get near you.

How To Choose The Right Car Battery Charger For Your Car

We have discussed so many types of battery chargers so far that it is bound to make you spoilt for choice and super confused. Here are a few points to keep in mind while buying a modern car battery charger:

  • Battery charger type

The most important point to consider while buying a battery charger is to make sure it will be compatible with the battery you want to charge. If you have AGM, EFB, deep-cycle, dry-cell, or wet-cell batteries, you must be sure to check that the battery charger you are considering works well with it.

  • Size of battery

Here, the first step would be to ascertain the battery size you are looking to charge. If your battery is rated 50 Ah, a 10 Ah charger would take about 6 hours to charge it. So, knowing the battery size helps you determine if you are looking for a charger that charges fast or if a standard charger would do. Smaller vehicles like lawn mowers and golf carts may require smaller battery chargers.

  • Purpose

It is helpful to understand if there is a specific purpose (other than charging batteries) that you need the charger to fulfil and look for one accordingly. Sometimes you would need your battery charge to serve a particular purpose such as being waterproof or you would need it to double as a power source as well. You could choose a charger with multi-voltage capabilities, or one that is a multi-bank charger so you can charge more than one battery at a time.
