Battery problems

[alan0259]

I have a 1998 CBR 600 F3 and I seem to have the same problem I had with my 2000 Hornet 600.

If I ever forget to start the bike with choke on and it fails to start, I turn ignition off, put choke on, try it again, but it never starts...

It's as though the failed attempt completely kills the battery.

When it's been running fine I have checked the battery with a multimeter on startup, idle, revs etc and all the readings have come out normal.

Even tried with the headlights off but it still fails to start, sounds good for a second then nothing!

Any ideas what it could be? Battery seems ok with the readings

Knackered battery I would guess.

The readings you have shows that the reg/rec is working fine and charging the battery when it should. It's just not holding the charge.

Yeah thinking about it, you're probably right!

I'll take the battery out this afternoon and I'll put it on a full charge, see how it goes then...

Cheers

Weird, just went home at dinner, started 1st time no problems.

Just seems that when an attempt fails (due to user error i.e. forgetting choke, or not blipping throttle on cold start) is gives up for a short while

I had a battery problem on my Hayabusa where it would start reasonably well and run for as long as I wanted, then if I stopped for a few minutes and tried again it wouldnt start. I would have to fire up the ignition, deactivate the immobiliser and wait for the needles to do their full scale thing and then wait about 10 seconds and it would then start.

New battery sorted that out completely!
