Hey everyone. Im having a small problem with my Cayman. I just took it out of storage and the car is having a real problem holding a charge. Im pretty sure its the battery. I was thinking of replacing it with an Optima Yellow top or equal. Im out of town right now and wanted to order a battery, does anyone have official measurements on the size of the battery(l x w x h) or a model number of the optima which will fit? Thanks
The other thing you may want to check 100% is the type of battery is currently in the car - I am going on the assumption that it is a low maintenance, but some here suggested that it might be a maintenance free - the difference is that the charging circuits are different. I believe the Optima are maintenance free.
The other little bit of information for people would be that if a battery goes dead, it will loose about 25% of its capacity, which is not possible to recover ( this is according to a battery FAQ on the Internet ).
Thanks for that info. I have had trouble with this battery before. When I was driving the car everyday, the battery died on me for no reason. The dealership said it had to do with my boomerang system but I don't think it was. Either way I would like to upgrade to an optima. Anyone done this yet?
Here is something related:

Sort of a thread hijack, but related...
On a related note...
I've been scouting out "gently used" or leftover '06's recently, and when I went to take it for a test drive, the sales advisor had to give it a jump. Kind of scared me off...it had been sitting idle for who knows how many months (had brake rotor rust, too).
I didn't know about the 25% loss as referred to above; should I get the dealer to install a brand new battery?
Thanks!
It shouldn't be surprising that a car sitting in a lot for half a year or so has a dead battery although I thought there was a TSB telling dealers what to do keep the batteries charged
Rust on the rotors is nothing. Any car's discs after a rainstorm forms rust. First time driving it the pads just wear it off.
A good thing to do if you are going to park your car for more than a week or two is to use a battery maintainer. Porsche dealers, Griots and most auto parts stores sell these for $35-75. These are special chargers that you can leave plugged in for months, if necessary, and will keep your battery charged without overcharging. I have used these for years with good results.
