I've been using the Odyssey 630 (or 680) miniture battery and my car is dead right now. I'm wondering if anyone else using this battery has had problmes with it. Things I noticed is it took a little longer to start up but that's about it. It does have 600 cranking amps I believe. I'm wondering if I need a bigger battery or what, but this ones fits like a glove next to my M2 Lg IC so I'm reluctant to do a batt relocation.

 

The smaller batteries tend to get drained easily. I've heard that you need to drive it every other day or so to keep the battery from dying. If you tend to keep it not driven for long, there are quick battery disconnect ***** you can get from auto supply stores. Also get a 9V plug in unit that runs to the cig lighter to maint. your radio settings.

Batteries in general tend to last shorter in FD since it gets real hot under the hood. Opening up the hood or keeping the key in the on setting to allow the fan running for a while after shutting down the car may extend battery life a little.
