FAQ:

Q: What is the voltage of a 12V battery?

A: The actual resting voltage, or the voltage a battery will settle at 12-24 hours after being removed from the charger, is closer to 2.1 volts per cell, or about 6.4 volts for a 6v battery, and 12.7 volts for a 12v battery.

Q: How do you read a battery charger meter?

A: To read the meter, you will have to plug the battery charger in and then turn it on. When you turn it on the needle on the meter will move. If you have the charger set to ten amps, then the needle will move to that point. As the battery charges the needle will drop.

Q: What is the size of a 12V battery?

A: There are different specifications. One 12v battery may measure 8 3/16 x 6 13/16 x 8 3/4 inches, while others are 9 1/2 x 6 7/8 x 8 5/16, 9 x 7/16 x 5 1/2 x 8 15/16 or 10 1/4 x 6 13/16 x 8 7/8.

Q: What is the charge of a battery?

A: A battery charger, or recharger, is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. The charging protocol (how much voltage or current for how long, and what to do when charging is complete, for instance) depends on the size and type of the battery being charged.
