FAQ:

Q: How many volts are there in a 12 volt 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: Can a 12 volt battery hurt you?

A: In fact, under normal conditions, a 12-volt car battery will usually not even shock you. Car batteries are not harmless, though. There are many ways you can be injured by car batteries: Car battery acid can leak out of the battery and burn your skin.

Q: Are most car batteries 12 volt?

A: Car Batteries Are Not 12 Volts. There are at least three variations of the lead-acid battery in current automotive use (1). In the most common configuration, the car battery has six cells, each producing about 2.1 volts.

Q: Will a 12 volt charger charge a car battery?

A: A 12v charger can charge any 12v battery. The difference is your scooter battery is 7ah (amp hours, for those reading who may not know) and a car battery is hundreds of amp hours, so it isn’t going to take very long to charge the scooter battery compared to a automobile battery.
