Mike,

If you've got one of those automatic chargers then use the higher charging rate and let the charger set it self down to a lower rate. The higher rate may do the trick, but don't leave the charger connected if the charger isn't one of the automatic types.

However... 427sharpe is correct in noting that if the battery was strong enough to turn the motor over for 5 minutes (!) then the battery is probably pretty darn good! Are you sure your voltmeter is correct? You're not using the dash voltmeter are you?

Hey, I found the specs for the starter on my Cobra. Max power current is 349A. Free running, 52A. Ok, let's call it 350A while turning over the motor. That's 350A for 5 minutes! I'd say the battery was doing the level best that it could.

How old is the gas in the tank?
