I need a battery
 
Hi Babblers!

Anybody home?

I need to replace the battery in my 2000 986S. Years ago I believe the cage was expanded to accommodate a larger battery. The current one is a big Interstate with 850 CCA.

Looking online, that model (MPT-93) has been discontinued. The replacement has a much lower CCA.

I am also concerned about fit. I do not understand the battery sizes. H6, H7, H8, 46, 48, 93??? How do these codes relate to one another?

I went to Wheel Works as they carry Interstate, but they did not have the large model, and will not install an OEM size as there have been mods (they will sell it to me over the counter which is what I want).

Consumer Reports recommends DieHard, Optima and a Walmart brand,

Any suggestions? Any help on how the size codes work?

The one you have is still on the Interstate web site. Ask them to order it. The Interstate site has the dimensions so with those and the CCA you can compare. Nothing special about a normal battery that Porsche used but, with your modification, easier to find an exact fit.

Thanks, Mike. That chart is very helpful.

I should add for any future readers that venting and which side the positive terminals are on is important.
