Duralast Gold (Autozone) 51r ("Honda" sized)
Just get one of THESE.
See pics. Fits great, I've had zero issues with battery for the last year. I have an ASP/M2 medium intercooler too (with stock battery tray). Cranks my motor just like the OEM sized battery did. Coldest temps have been 30-40 F during the winter. Warmest in high 90s.

FYI, I've had my PC680 since 2005 (mounted in my engine bay), and it's finally starting to show its age. During that time, the car saw some daily driver duty in 100 F summer heat, and quite a few short trips in 50F weather. During all that time, the only time the battery acted up was when the car sat for more than a few weeks at a time.
This year, I'm driving the RX-7 less and it's noticeably worse. If I let the car sit for over a week without driving it will be hard to start. After two weeks of sitting it's pretty much a guarantee it won't start. The car starts without problems if driven more than once per week. I picked up a trickle charger for about $20, I just charge the battery if I plan to let the car sit for a while.
Overall I'm pretty satisfied with my PC680, but I wouldn't recommend it to someone who didn't have another car for a daily-driver, or to anyone with an aftermarket stereo system.

has anyone ran or heard of adventure power? I found this which is supposed to be an exact replacement for the odyssey pc680, only lower cost and supposedly (according to them stronger) here is the link. http://www.powerstridebattery.com/pr...idproduct=2925
And here is a huge list of other adventure power batteries they carry.

Over the years on my various RX7's, I have used batteries from 4 lb gel cells to odyssey to Optima’s. While I am a firm quality believer and the saying “you get what you pay for” .. I have decided with batteries that, go small, go cheap because none of them last be it $40 or $180 dollars and at 40 I can by 4 and get 5 – 6 years life versus 1 to 1.5 years

I've had my PC680 since 2004 went through 3 winters and still running strong, I even have a system in my car and never had any problems, the trick is to not to have any type of alarm system that will draw power while park, I just made a fuel cut switch for safety.
I also diconnected the factory alarm so when the car is off there is nothing drawing power from the battery

Then after I finished the checkout process I found a side-by-side review someone had done with the Odyssey PC680. Turns out the adventure power battery is slightly taller (not by much... maybe a cm) and has pretty shallow threaded terminals. Oh well...
I'll take some pics when it shows up. I have never handled a true odyssey pc680 so I won't really be able to compare the two.

But the battery seems to work OK. It started the car just fine, but I haven't started it in any really cold weather. I also use a battery tender and disconnect the negative terminal whenever the car is parked for an extended period of time.
My biggest complaint is with the terminals. Instead of the M6 threaded terminals they sent me one with terminals like this:

I didn't feel like dealing with returning the battery and unfortunately the terminals are permanently installed (no way to change them), so I rigged something up to work with the new ones. Considering the negative reviews of the shallow threaded terminals, maybe this isn't such a bad thing.

Here is my post from the FB section regarding my battery expierence:
So a little history on my battery ventures. I started with my 1982 FB with a 450 CCA battery. I quickly killed that battery, as it was walmart special cheapie battery. The second battery that I bought was an Optima Red Top. 800CCA. Dead in 4 months. Then I bought my Exide Orbit battery. 850 CCA. It lasted for 2 months with repeatedly trying to start a motor with 45/45/45 compression on both rotors. Then it sat for about 18 months and it was used to start my buddies old ford truck with a 351. Started it right up. Yesterday I went to start my car after it sat for over 2 months with a bad rear end. My battery that I had in my 1985 was dead from listening to music while I was working on my car, so I figured what the hell, i'll try my deep cycle. Put it in and turned the key, the motor started after only 2 revolutions of the engine. The batteries are pricey at about $180, but WELL WORTH IT.
