Battery size (enormous)

[Al]

I have the standard massive 18 amp hour battery on the J1

Does it really need to be this big if running daytime only and with lights and a few non essentials removed.

It has DYNA S, green coils, standard starter motor, electronic tacho and possibly a brake light.

Any suggestion how i can lighten this installation would be appreciated.
Any suggestions for preferred alternatives that may be smaller and lighter appreciated also.
Motobatt, Gell matting etc.

I am think about sports useage ie. trackdays where sessions last 20 minutes tops.

This is the type you want, though obviously not this model, they are on ebay, I am thinking of one for my z1000j race/track bike. i will be using it on the road with a daytime mot. they have more cranking power as well.

make sure you get one with the correct amps though but these will give you an idea off whats available.

Thanks all, may go the Lithium Ion route because the objective here is to save as much weight as possible.

Agree, I think the way motorcycles will, in the future, evolve is via the Lithium-Ion batteries. Any significant reduction in weight is always a plus.
