jasper65 6 Posted May 12, 2012 Report Share Posted May 12, 2012 I have a old 4 Amp battery charger I have used for years. normally I just loosen off the caps and top up with distilled water if needed and leave the charger running for a day or so or a good few hours until I think its charged, I was told recently that leaving a battery can over charge the battery causing damage? I'm now thinking its true after I left my Old 580 AMP diesel battery running on the 4 AMP charger for a good 24hrs to find that one of the cells had packed up, also think I knackered up the ride on mower battery leaving it on trickle charge. the charger I use has a needle gauge, the needle is high when the battery if flat and drops off when its charging! its as old as the hills and has no indication when the battery is charged except when the needle drop to about 1?
