Battery Group size
Was reading this thread - lots of great info: New battery - why does all work so well?
My '88 Carrera has a Miata battery in it, mounted on a piece of plastic. Just not quite right for a variety of reasons... Not interested in a Braille or Odyssey battery - conventional is more my style. But the original battery is a big huge thing. There's got to be a size that works well... Group 48? 34R? Advice appreciated.

Not sure what's wrong with an Odyssey. They sell two different sizes, the 680 and the 925. I got the PC925T and it's been great.

I thought it was Group 44? That is what I have in my '78 SC and it is a perfect fit.

Craig_D - Nice set up you have. Thank for the pictures. However, am not interested in the $$$ of the Rennline battery mount.
Anyone care to confirm alternate Group size? Now we're got 44 and 49, and H& & H8.... My care does have two holes for the battery clamp, one for the original size battery and one for...? Would like to know what fits. Thanks

Interstate Batteries shows your car as a MTP-49/H8, which is the huge one. When I replaced my battery last year, Interstate was showing the smaller battery (MTP-91) for my 81 911SC. My car always had the huge one, so I ended up with an MTP-49. I suspect I could have used the smaller one and use the alternate clip hole and it was also cheaper by about $50, but I opted for the larger battery. The larger battery is not too hard to install - you have to tip it slightly and wedge it under the stationary clip, then just screw in the other clip.

I just go with the good old Bosch full size battery. Yea it's a tank.
However, It's been very dependable and has plenty of power. You can start a tractor with it. A lot of cranking power. Last edited by maui44; 01-30-2013 at 07:46 PM.. |
