I replaced my original battery last week, it was on it's last legs towards the end of last year and the cold winter in the garage must have finished it off. It was 4 yrs old so can't grumble.
I found this place online and the battery was £49.99 delivered next day. They also sent a £5 voucher for next order.
It's a Lucas and the cca (cold cranking amps) was stated as 200 which seemed to be what most of the other ytx14's were rated at in the below £70 price range. Some of the cheaper ones on eBay etc were only 120 cca.
Does anybody know if that battery fits a R1100GS? I am afraid it might be too wide (apparently a standard 1100 battery is 82mm wide; this one is 88mm).
What about a battery with a lower CCA (let's say 150)? Would that do?
