To begin, let us show you some of the most common versions of your car battery. All the batteries discussed are those that you may come across in your travels in the battery and electrical field, when it comes to your basic home repair, This also includes the associated car battery chargers that would help maintain them, which would prove useful if you had one type and then had to purchase a new one.

1. Flooded Battery

The first type of battery is or flooded battery. This battery type should be familiar to most anyone who has a bit of car mechanical savvy, for these should comprise a large percentage of the batteries encountered while performing this sort of work on you car. Therefore these should also be the easiest to find the appropriate car battery charger for. They contain a liquid sulphuric acid as the electrolyte, and this can be replenished with distilled water as the reactions lose water due to the generation of hydrogen and oxygen respectively.

2. Sealed Battery

These are of the same design as the flooded batteries, but the cells are sealed so that water cannot evaporate, and there is no need to refill them.

3. Valve Regulated Lead Acid

The VRLA batteries are the same as the sealed batteries, although now there are special valves built into the battery to allow the escape of the hydrogen and oxygen. Far less common than as the flooded battery, these institute a process that allows much of the hydrogen and oxygen to catalysis to reduce or negate the loss of water.
