Which OPTIMA battery to use?

[mountainbiker]

I pulled out my POS dead ACDelco (P/N 86-7YR) battery. It is making a nice paper weight in my garage. I also have a paper weight in the driveway called a H3.

I will trade you some battery specs below for pictures of your gel cell battery installed in your battery tray, and a description or pictures of your battery tray mods:

ACDelco (P/N 86-7YR)

690CCA and 50Ah

L: 9" *
* The battery box has plastic tabs on each end. If you remove the 3 tabs on one end, then you'd get about another 1/2". If you removed a wire fastener and 3 tabs on the other end, you'd get another 1/2". A 10" L battery would be tight.

W: 6-3/4 - 7" **
** The base of the battery is 7" but then it tapers in slightly to 6-3/4". I think if it was a straight 7", you might have an issue with the metal bracket that holds the nylon strap.

H: 8-1/4" ***
*** This includes 1" for the posts.

The battery box lid has some extra big holes for the terminals. On the width side, they are centered between 5" + 1-3/4". On the length side, they are like 0.8" + 7.3" + 0.8". It will be hard to understand, so it is probably easier for you to measure this one yourself.

Optima 25, 35, and 75/25

720CCA and 44Ah

L: 9.313”
W: 6.813”
H: 7.625”

Optima 34 and 34/78

800CCA and 50Ah

L: 10”
W: 6.875”
H: 7.813”
