Charging Question

[crazy4life]

What happens when you put a trickle charger on 1 battery when you have 2 batteries. Right now I just want to charge them up for the weekend but once I move to my marina where it is stored on the trailer I will have to come up with plan B because no electricity where the trailer storage is. 2019 AR 240 with 2 batteries. Thanks in advance for the help.

If the charger is made for one battery, it can only charge one battery. Lots of dual battery chargers with solar support available.

Right now it is hooked up to 1 of the 2 batteries but they are hooked up in parallel. Will this charge 1 of the 2 batteries or both or none. That is the question.

If you're on trickle charge, it's possible if you let it charge for a week. But I wouldn't redneck it like this - a cheap dual charger will cost you less than $100.

Please reread initial post and get back to me. Thanks

If it is wired in parallel



Then a single bank charger would charge both batteries as half the speed.

Thanks for the reply. Just wanted to see if I had to disconnect the batteries. This is just till the week end. I will then be moving it to the marina and will have to come up with a way to charge it by solar. I was reading several posts on how to do that but I got confused on cutting wires adding 1 of these and 2 of those and cutting something else. So that will be a battle for another day.

Wouldn’t it depend on how it was connected and how the disconnect switch was set?
If the batteries were disconnected (switch set to off) and he connected to the pos and neg terminals on one battery, only that battery would be charged?
To do what you described wouldn’t he have to put the switch in the third position (for when the first battery is too low to start the engines) and hook to the pos on one battery and the neg on the other?
