ive got 3 batterys that are not installed in any vehicles, 1 boat battery, 1 generator battery and 1 car battery. i have a solid state trickle charger that i use and i rotate the charger between the 3 batterys at 1 week intervals.
im wondering if i could solder on 2 extra pairs of leads so i could hook up all 3 batterys at once and not have to rotate them. i was thinking that the batteries would probably not get along to well hooked together so i would solder in a diode on each lead to seperate them.
what do you guys think, could this work?
Just wire up some more leads in parallel,it will work fine.At that low of a charge rate,it won't matter what kind of battery is hooked to it.
Yeah, it will work butthe outputwill be low, imagine the same voltage at each line and then a reduction by 3 in current to each battery. But if time is not important then you can work with the batteries. You will have some more losses with the extra cables ( not alot), but you could try an use a higher output battery charger and install extra leads to balanced out the current splits to each battery.
For maintenance charging,it will be fine.You are just trickle charging them anyways.
You don't really need to charge them that often.As long as the batteries are good,all three together should be charged for about 24 hours no more than once a month.
