I have a 99 coper/silver Busa. just 200 miles on it, no accessories. All winter long the battery was fine, I started and warmed up the bike every two weeks. Last week the battery was too low to crank the starter. I put it on a 10 amp charger and 10 minutes into it decided to put it on 2amp trickle charge(after reading the service manual). After fully charging it went for a 25 mile cruise. 4 days later, yesterday,I was able to start the bike went riding with a buddy 7 miles or so and stopped for a smoke. Could not start it back up, not enough power to crank the starter. I was able to get ajump start and rode back home. I was able to start couple of times after that and battery was low or atleast did not have enough cranking power.
I checked for a battery leak and it is below service manual specs.
Is it a bad Battery? Did I ruin it by putting it on a 10 amo charger?
Or is it related to the starting circuit drawing too much current?
Any help will be much appreciated.
I had battery do something similar, after 10 months. I would slow, full charge it. It would take charge, and start ok. However, the amount of time bike could sit, went from 2 weeks, to 1 or 2 days. Have other bikes, with batteries a year older, but no problems. Check charging system, on bike. Should be 14 to 15 volts. My dealer replaced battery under warranty. Had new battery, and bike back within 24 hours. (free)
Try carefully cleaning your battery contacts and cable ends. Make then shiny where they touch each other. This an obvious but often overlooked fix. I learned this from a North Conway New Hampshire car mechanic. He charged us $50 for the 2:00AM tow but only $5.00 to fix the major electrical failure we thought we had.
Thanks for the info guys, I talked to my dealer, will be taking the battery in to day.
Lyle, checked the contacts anf cleaned them real good. Let you know what happens.
Shame on you Frank,Hayabusa Batteries do not use water.That will ruin the Busa battery.
DO NOT uncap them it sound like it was either not serviced properly out of the crate (happens alot)or it has an internal short.
PS. starting and not riding the bike is worst thing you can do on a busa it need to run(not idle or stop and go)for at least a 5 mile ride to replace the charge it lost.
Idling the bike losses battery power fast.need rpm to break even.
The dealer here checked the battery and it was bad. It holds the charge but no cranking power. Replaced it right away. Seem s to work fine now. Thanks for your input.
My brother and Friends less than a year old ZX9s suffer from constantly discharged batteries, after charging then they are fine for a few days and then dead as a door post again - regardless of the amount of use the bike gets.
My R1 can sit for two months without being charged and still start on the button.
