Running 12A battery.
 

Dear Sirs,
My battery has completely died on my '03 KLR and I can only find a 12v/(more or less)12Ah replacement that fits. Any problems I should be aware of doing this?
Many thanks,
Cam J.

(Should've mentioned that the original is a 12v/14Ah unit)

I'm presuming the KLR is 12v but a lower capacity, say 6Ah. The alternator may not be able to charge a larger 12Ah battery if it's flat. If it's fully charged then it'll be ok to get you moving again. Long term it may not be wise though. It depends on the output of the alternator. Try asking the question on a KLR specific site such as Kawasaki KLR 650 Forums
Good luck.

The original on the KLR650 is 12v, 14Ah alright.. the only prob with using a 12v 12Ah battery is that it may not be able to start the bike as well as you'd like on those cold mornings because of the smaller "cranking" capacity. A 6Ah battery is a tiny capacity.. I'd imagine thats only suitable for 250cc bikes or smaller.. not sure though.

Once the bike is running, there should be no prob at all, unless you overload the alternator with accessories, in which case, the battery will die more quickly than with the 14Ah in, and the bike will die sooner as a result.

You're not running any third party CDIs or anything else that takes the power from the battery, rather than the (second) pickup coil? Stuff like this increases the dependence on the battery, so a good battery is even more important.

Thanks for the replies. I'll have to go for the 12Ah battery as thats all there is around here. Luckily I don't have to worry about cold morning starts and I certainly don't run heated grips. I only run one accessory at a time, such as GPS or charging camera/phone. Cheers.
