Battery Testing

PostPost by: john.p.clegg » Thu Sep 03, 2009 3:39 pm

Sorry for the postingitus.... but......what is the easiest/quickest/best way of testing a battery...I think mines past its best (it is 12 years old)...is it to put a voltmeter across the posts whilst cranking and measure the voltage??

Thanks

John :wink:

Wot! 12 years old & you only think it's "past its best" :roll:
I dumped my 10 year old Battery only 2 days ago, purely because the "Battery Jogger" wasn't showing either charge or discharge on either of the LED's.
That was enough for me to fork out 44? for a new replacement & peace of mind for another few years :wink:

Yes, what you are describing is correct. A fully charged 12v battery should give at least 8v when cranking.
