MIKE550/4:
hi all again

if a bike has been laid up all winter, battery disconnected, does not using the battery cause it damage

gave it a good top up , fully charged it up but nothing when put back onto bike

any tips apart from buy new battery

UK Pete:
Some of the cheaper chinese batterys, are very fussy and need a constant use or at least a trickle charge , or the power zaps right out of them and when totally drained they quite often dont recover, alot of the chargers these days have a battery recovery mode which can sometimes salvage a severely drained battery,

matthewmosse:
Optimate or similar charger with desulphate function is a well worthwhile invsetment. Other trick if that fails connect it to a good car / bike battery (jump leads pos to pos and neg to neg) then charge the good battery Saved my wifes 250 battery from the skip this winter.

Bryanj:
What you need is a variable output DC voltage supply and wind the volts up till the battery takes some current BUT you need to keep a very close eye on it for at least the first 1 1/2 hours

SteveD CB500K0:
Or buy an Optimate (or similar) which is more-or-less what they do.

... but you don't have to watch them  :)
