Chargers are used after a
car battery has lost some or all of its charge and is said to have gone flat. The charger connects to the car’s battery by means of crocodile clips, and sends an electrical current to the car’s battery. If you need to use a car battery charger, you must make sure that you carefully follow the instructions for operating the charger.
For a battery to charge properly, it’s very important that the battery fluid level is above the lead plates inside the battery. The charger will usually have two cables, these are normally red for the positive cable and black for the negative cable. The negative cable from the charger should be attached to the negative terminal on the car’s battery and the positive cable coming from the charger should be attached to the positive terminal on the
car battery.
Some chargers require connection to a mains electrical power supply while the charging is in progress. Other chargers are rechargeable, and don’t need a power supply. They can be used to charge a car battery anywhere and are easily carried in the car for use when required.
Also there is a green product — solar-powered
car battery chargers. These chargers simply plug into the 12 volt socket outlet in the interior of the car. They can charge the car battery at a low amp rate and can take a relatively long time to fully charge the car battery. These solar chargers are quite cheap and there is obviously no need for a mains power supply.
You need to know some important safety matters when you are using
car batteries and chargers. If you are checking the electrolyte liquid level inside the battery, avoid getting the liquid in your eyes, or splashing onto the skin.
The liquid contains acid which can burn your skin and can even cause damage to your sight. Be sure to wear proper safety goggles or other adequate eye protection and you should wear protective gloves to avoid skin burns. It’s also important that when you work on the
car battery and you are charging it, that you must avoid smoking. Gas emitted by the battery while it is charging may explode and cause injury or damage to the surrounding area.
