OK, who on the board is a battery & charger expert? When you call any manufactures....it's always the same double talk but no concrete answers. I have chosen to use Maintenance Free in 4 of the Classics. 3 of them I have no problem with and have gotten more years of usage than planned, but 1 of them there is a problem. Having 4 different battery chargers I use the one (which I thought would be the better. There is a NAPA 85-300A mounted in the trunk. This charger i have never used (I know...why not). Because I thought the M/F batteries need a special type of charger.
So who knows which would be a good battery charger for M/F?
