As to the life of a battery, my A7 6v has just died after 6 years of abuse. Its final demise was to leave it untouched for 11 months (My fault). The output now is about 10 amps max, enough for the coil, but not enough for the starter. Tried charging it with a smart charger, replaced some of the electrolyte for acid to bring the S.G. up a bit, to no avail. Likewise I have a spare 6v from my old 2CV (which I converted to 12v) - That's dead because it has been left uncharged for 2 years.
Best thing for a battery is to use it regularly !
