Odyssey battery in C6
I would like to put in the 925 lighter smaller battery than stock, but the metal box adapter box doesn't fit/bolt down well, and the correct battery (1230) is 20# more than the 925. Has anybody figured out how to do this with a clean installation? I have the 925 and box, but am about ready to give up and put in the 1230 with the correct feet to grab the factory hold-downs.

Do you race it that much that 5-8 lb will make a difference ? I drag race and in my case YES it would make a difference, BUT everything has a "give" & "Take"
In my case a lighter battery would help me go a bit faster.. BUT the downside is I drag race, and after each run while I'm in the staging lanes I have to cool the motor as quick as I can so I run just the fan with the motor OFF.. so a small battery would go dead after 3 or 4 runs.... therefore I went with a little heaver battery but its a DEEP Cycle.. and I don't have to worry about it going dead between runs...

Good question but, depending on which lightweight battery one chooses, it is more than only a 5-8 pound savings.

Yeah......I have a few Audi buddies that have done this in their TT's in a quest for lightless...What you sacrifice is cold cranking amperage and enough reserve to operate power hungry cars like the TT (or Vette). Most installs have been unsatisfactory unless you constantly keep one on a Battery maintainer, and live in a warm climate. There is NO free lunch in other words. If it could be done reliably it would have been OEM...

As with most mods, be it exhaust, tires or even seats there will almost always have to be some sacrifice/compromise tolerated in order to attain some further gains.

Thanks for the comments guys. I have given up the half-size idea. The Odyssey 925 (half size) battery is 380 CCA (cold cranking amps), 625 HCA (high for 7 seconds), and 500 MCA (medium or middle?) at 25 lbs vs 45.5 for the stock size battery. These Odysseys are supposed to last 8 years and be better than stock. But I think I will put in the same size as OE Odyssey, have it bolt right in, and try this new military design dry cell battery out. This group 75/86 battery has 730 CCA, 1050 HCA, and 815 MCA. It is $226, but in a car that needs a battery to open the door, maybe it is not a bad inverstment. These are totally dry, so can be mounted upside-down (obiously not necessary), and recharge much faster, and are supposed to last two years in storage when disconnected.
