Question about mini 1.3ah battery for starting a bike

[toyboy]

Was walking around Jaycar the other day, as you do...
and saw in their collection of SLA batteries a little 1.3ah 12v battery, about the size of a couple of standard rectangle 9v batteries stuck together, nice and small.
Was wondering if this would have enough juice to turn over a 250 bike to get it started if your main battery was flat?? be a nice little battery to store in the miniature storeage area under the seat for a quick jumpstart when your to lazy to rollstart in 2nd :)

You can get 2500mAh AA batteries.
I get the feeling a handfull of them would not have the grunt to turn over a 250.

Even a scooter battery may not have the grunt to do the job.

A bike battery is about 14ah so you'd need about 10 of them.

the one in my vtr is only a 7ah, wondering if it would be enough to plug into the existing battery to give it just enough for a crank over if the existing battery wasnt completely dead

ahh no, not enough amps there fulla

i think its all about the amount of cranking amps or dicharge the battery is capable of.those gel lead acid batteries simmilar to the ones in emergency
lights or security panels (7ah) won't cut it,but don;t quote on that:rolleyes:
