How much battery power to start engine

[Ingah]

Just wondered if anyone know/could hazard a good guess, at how much juice is needed in a battery before it will successfully start a bike a couple of times? (it probably won't start first time because it's been so cold).

The reason for my curiousity is that my CB500 battery was pretty much just put on charge because i went to use the bike, and it was dead. Again. Damn cold/fancy alarm.

I am sort of waiting, and want to go ASAP (and need to go ASAP too), but i don't want to go faffing around putting this battery back in, until i'm sure it's got enough in it.

I'm charging at 600mA. The battery is supposed to hold 8Ah (when full of course - i'm not waiting the 12 hours or so required to fill her up!)

All depends on the state of your battery to be honest m8. For the hassle involved, its no biggie to give it a couple of hours, and then see if it'll start ... Might not hold the charge tho ... so you'd be back to square one pretty quick.

Obviously, the best course of action is the full charge ...

It's a newish battery, bought end of last year. So it's probably fine, just drained. Got a deadline to hit unfortunately

If you're in that much of a rush why bother. Just bump it and park on a hill.

In the end after about an hour or a little more I put it back in and disconnected the alarm for a little while, and it was fine. Apart from taking about 20 hours to charge on arrival :/ Hmm. Can't bump start my CB500 on flat land and it's too heavy with no hills where I was i've previously in desperation ran with the bike to start it but as I can't jump onto it the rear wheel locked and it nearly took off. Only just managed to avoid dropping it that time. Won't be doing that again in a hurry Did work though.
