Battery voltage question

[seangee]

No problems but my last throw of the dice before giving up on the speedo  :\  and looking for an alternative solution.


My battery is about a year old. Left the optimate on over the weekend and showed a voltage of 13.65 when I got to it this morning. When I got to work it was down to 12.63, and has stayed pretty constant since. I have no alarm so its only the LED on a flip-flop to make people think I have one that's drawing any additional current.


Does this provide any insight into the condition of my battery or charging system. I never had a problem starting in winter and still don't.

12.63V is a good fully charged voltage,
the 13.65V you measured would only be for a few mins after removing the charger and would rapidly decay to the nominal 12.6 ish.
I would say ya battery is absolutly fine.
