Battery Capacity

Recommended Posts

I was after the Amp hour rating, I thought it was a 12V system?

Each lead acid cell is typically around 2.2v.

6 in series therefore gives 13.2v

Alternator regulated at something over 14v.

I know this doesn't answer your question...

but thought i'd chuck it in as trivia anyway :)

Possibly semi :offtopic:

Its being discussed in the automotive industry that within 10 years, larger cars could be running 48v systems, as the current is more stable and will be capable of running all of the cars components.

infact some BMW's do have a set of batterys under the rear seat for this purpose, and one under the bonnet just to crank the engine over.
