12 volt batteries
Is there any problem mixing 2 different brands of batteries
Forum Discussion
Jim,
A lot of this answer depends on the meaning of "Mixing".
If you are going to strap 2ea 12V jars in parallel, expect trouble. Even if the batteries came off the final line sequentially, they still will not necessarily play nicely in parallel. Lead acid batteries just don't do that well. But, one new and one old and from different supplier? You don't stand a chance.
I don't feel like going into the whole thing right now (again), but if you are short of capacity, charge both batteries separately and carry them separately and switch when you need more power.
