12V DC Battery FAQ
-
What does 12V mean on a battery?
12V tells us that the battery supplies 12 volts under a nominal load. The same principle holds for a 24V battery bank in that it provides 24 volts.
-
How do you get 12V DC on a battery?
There will be 12 volts if the batteries are wired together in parallel: positive terminal to positive terminal, and negative to negative.
-
How long will a 12V battery last?
Average 12V car batteries typically last three to five years, and manufacturers recommend always replacing car batteries once those five years are up.
