Question:

If I install two 12 volt batteries do they discharge and charge at the same rate?

Two 12 volt batteries wired in parallel will not necessarily charge at the same rate when using a battery charger such as the OptiMate 7 Select Smart Battery Charger - AC to DC - 12V - 10 Amp # MA57JR.

It depends on the amp hours of the batteries, and if you have different amp hours, the larger one will charge/discharge slower. But if they are the exact same battery, and both are charged equally, then it will be pretty close to the same rate.

I have added a link below to our entire selection of battery chargers for you if the # MA57JR is not the right choice for your batteries.
