Things You'll Need
Instructions
Plug the charger into a wall outlet. The best place to set up your charging station is in a place where it won't be in the way or need to be moved in the middle of a charge.
Hook the battery up to the charging pack. Some batteries have a cable that runs from the adapter and plugs into the battery; others may have a base to sit the battery on.
Ensure that the charging indicator is on. Most of the time this is a red light that only glows when the battery is hooked up to the charger. Some also have a meter to show the charging process.
Leave the battery to charge for at least 8 hours. Allowing a full charge each time will help your battery continue to charge completely instead of "thinking" that it is fully charged after only a few hours. Batteries can develop a "memory" and not charge after a certain time, if that is what it has become conditioned to.
Unhook the battery for use and repeat the process with a backup battery. Cycling the batteries this way means you always have a full one to use.
