Will this battery crank an R1?
http://www.csb-battery.co.uk/catalog/GP/gp_12120.pdf
Just curious to see what people's opinion is of this slightly odd but cheap battery!?
I've not bought it yet but am curious as to whether it'd take being constantly charged when the motor is running and whether it would have
enough umph to crank the motor?
Ta for any input,
Chris.

Looks more like a UPS battery for a computer server room to me, and the terminals look decidedly flimsy to cope with extended cranking draw if the
engine doesnt fire immediately.
How cheap is cheap by the way, you can pick up bike batteries that will do the job for £30 that weigh no more than that one
cheers

No.
It will definately not crank any ice.
It is not designed to supply that sort of current.
Experience is what you get when you don't get what you want!!!

Ta for that!
Cheap is £19.95...
It says that the maximum discharge current is 180A for 5 seconds? Wouldn't that be enough?
Is it better to go for a more expensive battery?
Any suggestions?
I'd prefer a gel battery if possible as my motor is rigidly mounted...
Ta,
Chris.

That probably would be enough for 5 seconds, but I think bike/car batteries are rated in constant cranking amps, ie you can draw 150 odd amps
constantly and it wont get upset. If the engine doesnt fire immeidately its going to burn out the terminals.
Im also not sure on what amperage an alternator charges at, it might be too high for that battery.

Stick with at least the bike battery (YTX 12BS) which is a 10Ah. Anything less could struggle.
I paid about 40 quid for mine including acid pack.

I think you will find that is a theoretical max discharge current.
You could not pull that sort of power through the 6mm spade terminals on that battery without them getting very very hot.
That is a deep cycling battery for UPS and alarm installations etc.
