How long can I leave my battery?

[FlightRisk]

Couple of dodgy things on my bike so I haven't been using it despite the nice weather.

Need to chase Mr. Honda for my bits.

Anyway how long can I safely leave it without taking it for a run? I don't want to kill my battery. I don't have a charger either (actually I think my folks have a car one that's so old it might be made from bakelite, I presume it's a trickle charger. Bloody slow anyway.).

I suppose starting it and nipping 5 or 10 mins up the road will just drain it more than charge it?

I didn't start my bike for 3 months and it fired up fine, but then I've nearly run a battery flat on another by starting it a lot (when trying to fix something).

I don't remember where I read it.

But a good battery will lose less than 0.25% of its charge daily from non use.

If you disconnect it, it'll take ages to go flat if it is in good order.

Buy an optimate or similar, it's cheaper than most batteries and will keep your battery charged.

Hi

Depends on the battery. Decent quality one will last ages, and even longer with occasional charging. Cheapo Sprint batteries seem to die very rapidly when not used.

All the best
