Battery Size-how Small Are We Going?

[Jonathan_F]

How small are people going?
I have a YUASA 18Ah (NP18/12) lined up. I have no CCA figure as yet.
This is a sealed motorbike battery from the Triumph Rocket 2.3.
Will this crank the engine? Will it last in service?
I\'ve seen a post with a Redtop 20 and 40 used. Have no source for these yet.
Any info would be useful.

Regards,

Jonathan

I\'ve had a pc680 in the car for over 12months. It does loose charge now and then or if i over crank the engine but been fine in service. Tiny battery too.

Im using the same, pc680, in my FD and very pleased with it

Good light battery.

Will be getting another for my project car!

I\'m using a redtop 30 and it\'s absolutely fine.  Cranking no problem and can stand 2 weeks plus and not be drained by the alarm.  Not cheap but a pretty compact thing.  Also has a nice carbon-effect case if you\'re moving it from the engine bay!

I sourced a YUASA YTX20L-BS.
I\'ll let you know if it can crank her (she\'s definately a she) later on.
