Hi,

Yes, it needs a different tray, or requires that you drill a hole in the existing one to accomodate it. I have spec'd a ¼" Aluminum Plate which a machinist friend is going to make up for me. I have considered making a batch of a dozen or so were there enough interest in doing so.

You need a type 34R to fit the Boxster w/o replacing the Pos (+) cable, but these are hard to come by, so a type 34 will work just fine. You'll simply need to add a 24" 1 ga. cable in place of the stock 18" one, $4-5 at Autozone.

Aside from all the advantages of a GMT Battery over a Wet Cell, it also weighs about 12 lbs. less...

Happy Motoring!... Jim'99

Guess you did not se my post. They should provide you with the Adaptor tray when you buy the Optima battery. It's plastic and is the same color as the battery top that you buy, either Yellow or Red. No need to drill holes or fab up a tray. If you use the Yellow Top it should fit fine with no adaptor tray. I say yellow over redtop because most have nice stereos in their Porsches and are also convertables requiring a deep cycle for that type of usage. It's also what our in-house tech guy recomends (D34 Yellow Top) here at JCI. This is from our brochure:

OPTIMA YellowTop Benefits
* Dual Purpose starting and deep cycling.
* Lasts up to 2 times longer than other batteries.
* Constant performance quality keeping your battery running at the same level even as it's being discharged.
* More power in the initial 1, 3, 5, and 10 seconds of the starting process than comparably rated conventional lead acid batteries.
* Ideal for seasonal use, fully charged, it can sit unused for up to 12 months at room temperature (or below) and still start a car.
* 15 times more resistant to vibration than other batteries.
* Nonspillable and can mount in almost any position.

If you drive your boxster say once a month or rarely i recommend Deep Cycle batteries, those battery are meant for long storages usually used on boats.

Conventional battery aren't meant fro storage for long period of time, but you could solve this problem with a battery maintance charger.


For COLD COLD weather, there is somethinc called Cold Cranking Amps abrevated at CCA on the battery. The CCA determines the battery ability to crank the specific Amps ( its what makes your starter turn) in a cold temperature. The higher the CCA the better i recommend 600-650

Have a nice day, if there is grammar/misspelling issue my bad i'm typing this 4 in the morning

Yes, he is right, that is why I keep telling everyone the best battery your money can buy is a YellowTop Optima. They have 750 CCA. Yellow Top Optimas are deep cycle batteries.

Unless you are going to leave your car sit for long periods and own it more than 7 years, IMO the $70 700 amp cold cranking battery is the better buy.

Hey, porsche986spyder, how about a company discount for the guys (and gals)?

thanks for all the precious information...

After changing the fuse, my BMW is now unlocking fine but I need to take care of the battery...I am due for a new one anyway and will buy one of these plug-ins battery chargers at Walmart to -hopefully- get my car going.

I will shop around and look into the batteries that were presented on the posts.

The weather in STL is a little better but I need to address this asap...Vanessa
