12 volt batteries
Is there any problem mixing 2 different brands of batteries
Forum Discussion
Different brands must mean you have an older battery and are wanting to install a newer 2nd battery?. NEVER NEVER mix old and new batteries regardless of brand. Now, it is the right thing to do, to use same brand/model battery and same age. If you are mixing different brands regardless of new and old, are they the same CCA rating. You do not mix different CCA rating batteries, you will have a hard time charging both fully and then the different batteries will also discharge at different rates. It will just open up a can of worms. Doug
