I let the battery connected while the car was in cold storage with temperatures below zero for a week or so. Found out the hard way that the security system drained the battery and it froze. Tried to recharge it but no go. I just bought an AC Delco Professional battery to put in it in a couple of weeks. My stupidity, but it won't happen again.
Why in the world do you want to do this????? This forum is loaded w/ thread after thread regarding premature cell failure w/ Optima batteries.... Do yourself a favor----buy anything but an Optima.....
So true. theres a lot of hype,on that optima battery.Seem's people alway's want to join the masses,wether good or bad.I've alway's replaced with wally world brand's.And never a problem.And very affordable.If you got's the bejamin's spend them.
After my OEM battery died in my '97 at the end of its usefull life, I put in an Optima Red Top and used it for 3 trouble free years of New England (winter included) and had zero problems with it.
1 What's wrong with a diehard battery?
2 What about uping the amps on the replacement?
3 Did anyone hook a 9 volt battery on the treminals before removing it to keep and your settings?
