i know that the oddysey pc680 has less cca's than a 51 size battery which sucks for a car that sits for a while. but would this battery be a good fit for a daily driven car?

 

youll have issues during winter..
unless you have a tender on it..

 

My PC680 seems to have no problems if I drive the car at least every 2 weeks.
In the winter, it defnitely seems to be "dead" a lot. (Because I drive the car much less and it sits more and also because it's a little harder to start when it's brutally cold out)

 

i've been using it for a year now.

i use my car about once a week during warm months and sometimes let it sit for 2 weeks or so in winter. the battery hasn't let me down yet. starts up every time.

my last FD would discharge a full size yellow top optima if i let it sit for more than a week so your results may vary. i think it was the aftermarket alarm that was draining that car.

 

Oh and the other bummer thing about the pc680 is that you don't get too many "tries" to start it. If you have a hard-to-start car that requires a lot of cranking... forget it.

In my old Turbo II that sometimes had flooding problems (before I installed a fuel pressure bleed), I had the biggest damn battery that would fit. I swear to you I could crank that thing for a half hour if I needed to

 

i see. i think ill be relocating the battery then. it wont cost me much more and ill free up more space. hopefully that will go smoothly. seems simple enough

 

I had the PC 680 in the engine bay and hated it. I always had trouble with the car not starting. I ended up having to pop the hood and disconnect the battery every time I drove to work. If the car sat for more than a couple of days, I would have to jump start it(and the battery was brand new). Maybe my underdrive pullies added to the problem...

I finally broke down and relocated an Optima Yellow Top 51r in the rear bin and things are all good...

 

is it in a battery box or is it just chillin back there?

i want to do this mod!

 

optima batteries suck! mostly people with systems have them...they need the extra power for amps and ****..

odyssey PC680 is a great battery, i've never had a problem with mine, even if the car sits 2 months they crank right up...

 

bullshit.


I got a PC680 back in August. Drove car once a week. I just went out today to start her up since it has been 3 weeks now since I took it off the road. Deader than a doornail. Not buying another one of these ******* after reading that one pill of Viagra could last longer.

 

not bullshit...my car sat for 2 months in florida heat w/o being driven, i came back from vacation and it started on the first try..

 

I used to have the PC680, and it just seems that with FD owners it can go either way. My car was fine for the most part, but if for whatever reason I had to repeatedly draw juice from the battery, it would need to be jumped. I would also notice that it was harder to start when cold Besides space, I figured the batttery was one of those things that I could mind being a bit heavier if it meant I wasn't going to be stranded anywhere by chance, so I purchased a 51R and things have been fine since. Cold starts aren't a problem at all.

 

I had a PC680 that I killed due to a shorted stock stereo (speaker short killed the stereo). I took it out and killed a 51R before I realized it was the stereo. I ran a 51R for a few years and recently switched back to the PC680 because I didn't have space for anything else with my new setup. My dead-3-years-ago PC680 charged right up and worked okay (not great, but it worked). I replaced it with another PC680 since then. It does die if you let the car sit for a while, but it works fine if you drive it often enough. And they seem to be very tolerant of being discharged and recharged.

Yeah, I'm with Max on this one. My FD has been a toy for the better part of 4 years now and I've had the PC 680 in there in that time. If I know I won't be driving it for a while (ie couple of weeks), I take the negative side off. The alarm system in that time can drain it enough not to have enough power to turn the car over.

Seems like the owners of the pc680 that had troubles had some kind of small constant drain from somewhere. I used one with great success.. someone mentioned theirs died after 3 weeks, that could be expected...but unplug it or if you only driving it once every 3 weeks get a jumper pack..well worth it imho

 

I recently replaced my PC680 with a PC925...

I pretty much always run the fans after shutting off the car, usually for 5-10 minutes. The 680 was pretty touchy about this - half the time, that would drain the battery to the point that it wouldn't start the next time I drove it, and the other half of the time, it would fire right up. This gradually got worse over time, to the point that it couldn't even start the car if I didn't run the fans at all. I started carrying around a jumper pack for this reason.

The battery was obviously degraded by this point, so it was time for a replacement - I decided to try the 925 (next size up). HUGE difference! Now I can run the fans for an hour or more (when I forget to turn them off), and the car fires right up with no hesitation the next time I drive it. With the 925, I can even have the stereo on when the car's not running - I couldn't do that for long with the 680!

The PC925 is about 10lb heavier, and $40 or so more expensive, but at least in my case, it was completely worthwhile.

 

No, I cut the bottom of the bin out and bought a battery tie down kit at Kragen. I drilled two holes in to floor of th car and stuck the "J" hooks through them. Worked liek a charm. Just be really careful that you don't drill right through a fuel line underneath the driver's side. That would have sucked big time.

 

i run the Odyssey 925. 445 cca.

i bought it in may of '99 and it is still excellent. it is a nice fit in the pass side rear stowage compartment. i put a tender on it during the winter months but have had no problems for 6 seasons.

you do need to disconnect your battery or trickle charge it during non-use as the rx7 does draw a modest amount of current while "off."

How much bigger is it?

 

pc 925 is 6.66 long 7.06 wide and 5.75 high 25.1 pounds. about $125

I've run 680's for 4.5 years on my Stealth (I'm on my 3rd one) and I've been running one on the 7 for about 4 months. I like em...you just have to treat the car like it doesn't have a battery when it's off. Besides a quick window or sunroof movement or a quick download/upload with the laptop do not use the battery's reserve. No listening to the radio with the car off...EVER.

Make sure if you have the TSB coolant fan box you cut the thermoswitch wire that feeds it so you fans never stay on either. There's no way a 680 will hold up to that.

If your car has some sort of slow drain besides the normal security system/memory functions the battery won't hold up to that either. That's not the battery's fault though...its your fault for not fixing the problem. A bigger battery just masks it.

On a side note if you ever accidentally discharge it they're usually damaged permanently. They may be decent but they'll never be 100% capacity again. At least that's my experience.
