CRF150F Battery Charging Issue
Posted 19 May 2013 - 07:17 PM
Replaced battery twice, rectifier once. Currently running a Yuasa battery that looks just like the original but without the Honda logo. Dealership says it's a known problem with no solution. They say to use a Battery Tender. My storage facility has no AC outlets, so I can't just keep it on a tender.
I put a voltmeter on the battery, at idle it will slowly build voltage. Rev it above an idle and the voltage drops quickly. I'm pretty certain this is not normal. It's an air cooled engine so it doesn't run at idle often. Result is that after running the bike around for a good part of the day, pushing the starter button will not turn the engine over. Put it on a battery charger for a while and everything is fine.
No kick start on this model so a dead battery is a pain in the rear. I often run in sand so bump starting is not easy. Any help you guys can give will be greatly appreciated.

Your dealer doesn't know what he's talking about. I have 3 CRF250Ls and there are a dozen others in the valley and NO ONE has this problem.
Get the Service Manual and use it to check the electrical components and you will find the problem.

speeds but at high RPM it would make contact to the case and not charge.
Definitely not normal. I put in the lithium battery and it can sit for months and still start.
