Just got a Diehard Platinum (made by Odyssey) and found it doesn't quite fit without a little help. Its shorter and less deep than stock (or even an Optima, which was in there before).
I had a length of aluminum stock (1/4 x 3/4) and made two lengths of 6 3/4".
I set them under the bracket, side by side, and also had to use two small pieces of ABS plastic on the core support side.
Snug as a bug, now!



I knew that piece of aluminum would come in handy someday! I think I bought it over ten years ago to make a stock for a paintball gun, but ended up going a different route. I had about 5" left over and that went into the toolbox...just in case!

 

hehe, I went the redneck way. Piece of wood under my battery

 

i have been looking at those batteries my self. nice heads up.

 

I have battery spacers that fit under batteries Makes them a 1/2 or 1" taller and stuff.

 

does Procomp make Odyssey?

 

you sure its the right group? batteries from the same group should be the same size

 

Well, I'll be damned!?! Years ago when I got my first Optima I was told to use a 34/78 and kept using those same #s.

Stock group size is 25. Hmmmmmmm....

Here are both batteries:
34/78 http://www.sears.com/shc/s/p_10153_1...tive+Batteries
25 http://www.sears.com/shc/s/p_10153_1...tive+Batteries

The group 25 battery is almost 9" tall and with the 34 being almost 8" (needing a 1/4" of spacer help), there's no way the 25 would fit.
Looks like the 34 has better specs, though.

Will there be any problem? Never had one before using the 34 for the past 10-11 years.
