I used my dump trailer yesterday. I charge the two 12v deep cycle batteries by connecting them to the tractor battery, while I using the trailer. I idle the engine on tractor when dumping. The charging current never exceeds 15 amps. So my trailer batteries don't really get totally drained.
I put my trolling battery in parallel with trailer battery, because the trailer battery is getting old.
Last night I put a 15 amp craftsman smart charger on the two batteries. My battery minder was being used at another location. Well this morning the charger never shut off, only 5 amps, and the old battery was warm and smelled like rotten eggs for the first time. The newer battery, the one in parallel with the older one, wasn't warm or smelling.
I always thought batteries smelled because they were over charged. So how can one battery be overcharged while the other one isn't? The charger was actually connected to the good battery. Don't see how that would makes a difference. Electrolyte levers are good in both.
BTW, if this battery dies, it will be the first one in 4 years. 4 years ago I purchased a batteryminder 12348 charger. Guess in the future I won't use the crapsman dumb charger unless I connected it to a timer. George
