I also disagree with John and "avoid electric", but do see his point, as your light hour usage will mean that some days you don't charge the battery at all, and other days you may have to wait until it is charged enough to run the hours you will need it. and also that the battery will be the major expense, as a good battery (and no matter who hollers, in my humble opinion, there really ain't no such thing as a used good battery, reconditioned or not), that said, a good used electric powered forklift can give many years of added service, and with a well maintained battery, you would have years of almost trouble free operation, with the primary trouble being remembering to charge the battery when it is low and you know you will need it the next day for a few hours.
I am soooo tempted to harass John, by saying something like "he is remembering the electrics of his day" (he is retired, I remember him mentioning in another thread, but I should not throw stones either, as I ain't no spring chicken), and used electrics of today are much better, heck you would not want a used black and white TV these days, but they did do what they were designed to do.
