Never heard of them...for only $20 more, I'll still take the Odyssey. thanks for the link though.

I bought a used 78 R100 at the end of 2005. It came with a PC680 installed. I don't know how long it had been in there but it is still working as strong as the day I got it. I now have the PC680 in all of my bikes.

Yes, please let us know how it works out. I think you will be pleased with the Odyssey. Click Here for the data on the PC925L from the manufacturer's site. The way the battery is pictured on that page is the way I have it mounted in my bike, with the terminals facing forward.

I find it interesting that the Motobatt battery listed earlier in this thread shows a weight of 14 lbs. and the weight of the PC925L is 24 lbs. Yet the capacity of the Motobatt is 32 amps, and the Odyssey is 28 amps.

in my K1100LT

I put an Odyssey in my K1100LT, which is a battery hog. If the volts drop too much during cranking, you get ABS faults.
It was handy to have the bolt-on tabs, I reversed one to make it fit better. That is some handy flexibility.
I have never seen the motor spin so well for cranking, and I have not seen ABS faults since.
I put it in last summer, we will see how it does over the winter. I need to throw on a trikle charger. If we ever get some temps above freezing, it will ride it!
Cheers,

I want to revive this thread to see if the airhead owners using the PC680 have run into any issues with the lower amp hour rating compared to the Odyssey PC925.
Conditions that can overwhelm the stock airhead charging system like extra driving lights, electric grips or clothing, low speed in town riding/idling is what I'm curious about.

Thanks,
Mark

I bought a PC680 about three years ago, while I was building my bike and for the first year it just sat there. No charging or discharging. Fearing that I might have ruined the thing, one day I connected it to my Battery Tender and after about 10 minutes it showed a full charge!

Since then I've used it and abused it. Ran it dead twice from several hours of idling the bike around the grounds at Redmond, left the lights on in the garage one night, the dash clock is always ticking, etc. The battery has stood up to everything thats been handed to it, and it still holds it's charge forever.If my results are like most everyone elses, I expect it to last another three or four years minimum and I'll never have to replace another acid eaten the battery box.

Whats not to love? .

Pc925l

Droped right in to my '84 R100rt. Got it on the way to Redmond last year.

Love it. Not going back to lead acid.

The "L" is the one you want, NO adapters are needed unless you want a new shorter Ground leed.

Odyssey Batteries

I've been using Odyssey PC680 for my bikes and others. Plenty of CCA for an Airhead.

The PC925L has more, but IMO not necessary--and not justified by the weight increase. I'm heavy enough, adding 9 more pounds weight up high for CCAs that the bike doesn't really need, doesn't make sense to me. Nor the wrestling with it and possibly crunching my tool tray. Heck, I used to have an oversize battery with 365 CCAs, more than it came with new...and that was enough. Just my opinion.

PC680: 15lbs, 680CCA (L7-1/16" x W3" x H6-9/16")

PC925L: 24lbs, 925CCA (L6-15/32" x W4-7/8" x H6-7/8")
​

I had a piece of wood to fill the gap, but now have a piece of styrofoam painted black on my RT. On the R75/5 SWB, nothing.

 

[moose738]

Yep

I had this battery model in my '78 R100/7. It was oriented on its' side and fit fine. However, it was just a little to tall for the tool tray. So I rode around for a year with the tool roll in my saddle bags. Turns out I missed the tool tray more than I thought I would. Took the battery out a few weeks ago and put in a Model680 Odyssey. Plan on using the bigger Odyssey for my camper. The 680 has started the bike well in the cool garage; I expect it will be even better when the weather warms up.

Regards, John

Thanks for the feedback. I've had a PC680 in the wife's K bike for four years and in my R1100RS for two years with no problems. Great battery, just never used one in the R100. The old Yuasa is toast. I'll crack the frame one last time to get it out. It will be nice not to have to do that again along with checking electrolite levels etc etc.
Got a care package from RePsycle today, filters, crush washers, petcock rebuild kit. Looking forward to some quality time in the garage now that it's above freezing.

Pc680

I am running a PC 680. I am on my second one.... the first one's life was cut short and I thought it warranted a refund... but after 7 years of use and over 100K they told me I did good.

umm, you never did have to "crack the frame", tho you are free to do so if that's what you like.
alternatively- pop the air cleaner & covers off, and just pull it out thru the front, above the trans. top up & back, bottom slips out just fine. should be no issue.

On my airheads I personally found it a lot easier just removing the two bolts to "crack the frame." I guess it's just personal preference.

 

[bikerfish1100]

bizzarely, a friend of mine bought a new '76 R90/6. When he finally needed a battery replacement a few years later, a wtench at the dealership (in a podunk CT town back when that kind of location was suitable for BMW) told him to "cut the sub-frame and then re-weld it".
Fortunately, he had more sense than that wrench did.

I'll look at that method again. It's been a while since the last battery replacement. I remember being concerned with tipping the battery and spilling acid. With the unbolt the frame method, I knew I could keep the battery upright the whole time. Thanks for the reminder.

The Odyssey batteries are sealed, no need to worry about acid. You can mount them in any orientation.

 

[flat_twin]

Yes, you're correct the Odyssey can be mounted in any position. The old Yuasa is the one that could spill as it's installed or removed.

One of my acquaintances who used to own an Airhead shop, proved to me beyond a shadow of a doubt that cracking frame is the fastest way to install a full-sized battery.

With a PC680 theres no reason to bother!
