Battery Charger
1 Answer
Do you have a car battery that is losing its power? You can use a battery charger to bring its power back. A battery charger is a device that forces electric current through the battery. It is useful for batteries that are constantly used and for batteries that have been idle for a long time.
Batteries provide electricity by converting chemical energy to electrical energy. When a wire is connected between the negative and positive terminals of a battery, electrons in the negative terminal quickly flow to the positive terminal. A battery charger reverses this flow by moving the electrons from the positive terminal to the negative terminal. It can use electricity from its own battery or from an alternating current (AC) outlet.
Capacities of car batteries are measured by cold-cranking amperes (CCA). CCA is the amount of current a battery can supply at 0 degrees Fahrenheit for 30 seconds until the battery loses its power. The time required to recharge a battery is based on its CCA. Basically, the same amount of energy that was consumed must be put back into the battery by the charger. The more powerful a battery charger is, the faster it can recharge a battery.
There are two major types of battery chargers: trickle-type charger and fast charger. A trickle-type is usually cheap and can be plugged into household outlets. It only provides two amperes of current, so it takes a long time to fully charge a battery. On the other hand, a fast charger can supply 100 or 200 amperes, so a battery can be charged in less than an hour. However, this type can cause too much internal heat in the battery, so you should be very careful when handling it.
If you are going to charge a car battery, make sure that the charger and the battery are compatible. Carefully read the instructions on how to install the charger to avoid any accidents.
