have you had trouble starting your car. i just purchased a blitz fmic and since my battery just died i ordered the pc680. put it in my car and it didn't start. the cold cranking amps for the pc680 is 280 and the cranking amps is 680. i read on the national tire and battery website that the minimum number of cca's that our cars need is 350. anyone else experiencing a problem w/ this battery? i ended up jumping my car to get it started, let it run and then turned it off. i started it again and it started. so now i am waiting till the morning (about 8 hours from now) to see how it starts. just wanted to see if anyone else was experiencing a problem. i was thinking of ordering the pc925, and keith told me i should've done it, and now i'm kicking myself in the @ss for not getting that one. does anyone have this battery and have issues w/ a fmic? thanks

The only problem I have ever had with this battery is letting the car sit for a month or so without really running it. I initially installed it a couple of years ago, ran the car more regularly, and never had any problems. Now that the car sits 99% of the time, I trickle charge it before taking it out.

Mine allways starts and i've even shorted it a few times. I don't need CCA's though, because even during winter it rarely drops below 60 here. How cold is it there? Maybe that's the problem. Oh, and don't expect to use the stereo with the engine off.

I have had no problems with mine, it went flat after two months of sitting during the winter before I disconnected it, however asides from that it has started every time. It sounds like your battery is either not charged correctly, or has a problem.

Does anyone have the fan mod? I do and it seems to work OK.

I have it in mine and it has started fine from they day i bought it. If you let it sit alot disconnect the hot side,car thiefs hate that too...

i put the same battery in and mine did the same thing as yours. then I went to jumpstart it and noticed I never connected the ground.
since then I had no problems you should check your ground.

i let it sit overnite, ~9 hrs, and i went out again this morning. the voltmeter showed 12.91 v before i started. it started fine this morning, took it out and it started fine again. maybe since the car sat for 4 days, and prob was loaded w/ gas that was why it was hard to start. but i don't have any problems as of now. i don't live in a cold area at all, nj, but i just thought the cca's were kinda low, as were the actually cranking amps that this battery produced. thanks for all the replies.

Oh, I posted this in antother thread but...
the last time I shorted it I blew the main fuse. I couldn't see the break through the peep hole. I unscrewd it and removed it and then I was able to see the break. The auto parts stores only carry 80am and it's a 115amp (i think) but it has worked for over a week now because I keep forgeting to order the other one. I had even bough a replacement battery but it was just the fuse.

I know this is a little late but I was doing a little research and ran across this post.

I daily drive my car and have had the 680 installed for 6 months, in that time I've had to charge it about 7 times. I think the problem lies in its VERY low reserve. Basically the battery delivers 680cranking amps for 5 seconds when you crank it up. After 5 seconds it drops to 280 cranking amps. This tells you that the battery is using up almost its entire resources in that first 5 seconds. If you make a lot of short trips like I do your going to kill the battery. I use most of its resources to crank the car then drive 15 minutes and turn off the car. That 15 minutes doesnt give the alt enough time to get the battery back to 100% so everytime I crank the car is gets lower and lower on resources. After about 4 short trips in a row its dead as hell.

Also, if I let my car sit over a weekend with the alarm on it will pretty much kill the battery about 70% of the time. I guess it just depends on how charged it was when I let it sit.

Anyway, I'm getting rid of it.

never had a problem with mine and my car sits for days at a time without running. I have adjusted a few things...i never run the stereo unless the cars on. I turned off the dome light so it doesn't come on when the doors open. I check the charge on a regular basis...I havn't had to recharge yet.

Mine is good. I just need to start the car every 2 weeks and for a short 15 minutes drives is good enough to bring it back up.
The one time I left the interior light on for 5 days is the only time it kill the battery. I then followed the charging guidelines in their website, and the battery went back to normal.

So my experience has been good with it. I think some cars drain more power when off. Perhaps the ECU has some effect on this too. I have stock ECU and no alarm.

what about that odyssey pc925 battery. I was thinking of getting that one. Is it possilbe though to mount it sideways to fit in the rear bin? I don't want to cut my bin up to make it fit.

Thanks

Yes it is. That's where I have mine. There's a pic HERE, at the bottom of the page.

I had problems for sure. I wound up going back to a bigger battery and cutting a slot in my rear compartment to accomdate it. Maybe it was my stereo or some leak but since going back to a normal sized battery (Optima) I haven't had any issues.

I have one, my brother has one and one of my buddies has one. The same thing happened to all 3 of us, battery died...the thing will die if it sits for a while and it will NOT recharge.
We traded them in and got new ones (2 year warranty I believe). Just don't let it sit for long with out a charge.

rxrotary2_7

nick i was saying that if you let it sit, it will drain. thats why i went to the 925... you know my cars, they can sit for months on end without getting attention. i did drive the FD the other day after i changed the WG spring and did a little more tuning. if let sit for a few hours its not a problem starting, but after a week or so it is a bit hard. espicialy since it usualy take about 4 time to get the motor to start w/ the haltech when motor is completly cold but starts right up after warmed up.... i gotta figure that one out yet....
yes it can be mounted sideways.

I'm on my second one....the first lasted a couple of years, but a cold winter and leaving an interior light on one freezing night knocked it out of commision. Once the 2nd one dies I'm relocating a big mamajama to the rear compartment.

may i ask what is holding that down?

There is also a smaller sized optima for $100 at Costco that should fit well in the rear bin. I tried to use it in the engine but I couldn't reach the terminal posts as they are 2/3 to the pasenger side, instead of to the drivers side. It has a plastic spacer stand to put underneath but you will have to extend the positive termial somehow. This version might work, it says the terminals are reversed . But I don't think Optima's are gell filled like the Odyssey.

Looks like even the yellow top is a sealed lead acid plate something battery but you guys that winter store may want this one. I'd still rather have the gell filled Odyssey but i'd have to fabricate some kind of hold down for the 925. I do have a cheap idea though: Those metal bracket things for the garage door openers (with holes in them) that you screw in to the roof. Cut a peice in to 4 and screw it down. If someone wants to make & sell, weld the corners.

I have a '51R' (I think) its from a Honda.
I paid $35 at a K-Mart closeout.
I fits in the rear bin (with a little stretching and shaving the back corner of the battery.
Absolutely no problems starting and the tight fit makes sure it wont move.
I didnt have to modify my bin except for drilling a hole for the cables.
I used the drivers side because the pass one is easier to use for other stuff and it locks.
I dont think the weight on either side makes enought to worry about. I may run an extra hold down somewhere down the list.

At the moment, gravity. This week I'll be slotting the bottom of the bin so that I can strap it down. Actually, the battery fits exactly in the bottom of the bin and doesn't slosh around at all. Otherwise I would have done something about it much sooner.

And yes, I know that it'll be a hell of a projectile in an accident, and it'll never pass any sort of tech inspection like that. I'm not yet willing to cut up my bin to mount it to the frame.

have you charged the battery? New batterys should be recharged before you use them as they may not have been recharged for a long time before you buy them. even regular batteries with high cca need to be recharged regularly unless your alternator is not working or you don't go on cruises where you run your car at 3krpm for about 2-4 hours.

You should take note that you can not charge a hawker/odessey battery with a regular charger. It takes a particular charging algorythm that most chargers don't adhere to. Deltran makes chargers built for this, or if they are fully discharged, you can take them to a "Batteries Plus" store to have them recharged. I had a few 680's that were completely discharged, and they brought them back to life for $5 each.

If you can't charge them with a regular charger, how can the alternator charge them ??

I use a 'Battery Tender' for my FD and my Motorcycle, both of which I don't get to drive nearly enough
