Jump start bike with car?
 

Well, MOT day tomorrow, only just remembered :rolleyes:

Last time I tried to start the bike it took a worryingly long time to come to life after all that time sitting in the cold. That was a over a month ago, I havent dared start it since.

I had planned on getting a charger before the MOT but it seems I had my dates mixed up...

So, worse comes to worse, if she doesnt fire tomorrow, is it safe to jump it off the car? Google tells me I can but there are a few mumurs of damage possible due to the car battery pushing more amps or something.

Rather trust the org to tell me - safe enough to do?

yes fine, just dont start the car engine as the car generates too much power to charge the bike battery, starting the bike has little effect on the car battery overall

Care to explain why? As long as it's a 12V system you can do what you like, of course the car's battery won't even notice the bike is there so there's not even any need to have it running.

There is no such thing as 'generates too much power' in this circumstance.

i agree with tsm mostly
depending on your car you could still have the engine running like my Suzuki Alto, the battery is same amps and amp/hrs only bigger in actual size.

Battery capacity is irrelevant, a 12V system is a 12V system.

That's what I was hoping, but had to check!

I cant visualise my battery terminals...will I have space to get jump leads down there (the ones I have are quite chunky car ones) or will I have to manipulate the battery?

Re: Jump start bike with car?
 

too much current then, you should not charge a bike battery with high current or it can damage the battery, prolly a long time thing rather than a one min dont know

Re: Jump start bike with car?
 

i just clamp negative to bike frame and then leaves me only to deal with positive terminal while handling the battery for positive connectio

I with sid squid on this one, you wont need to start it, but it will charge if the car was on.

Re: Jump start bike with car?
 

it will charge regardless anyway even with the car off as it will draw current from the car battery till its either full or balanced between
SidSquid will prolly write somthing far better to understand than me
