Why are you never supposed to mix batteries together?

Not only should you not mix batteries by type and brand, you shouldn''t even mix them by batch. The reason: if one battery is in a state of discharge compared to the other, the stronger will charge the weaker. This can cause alkaline batteries to leak or burst.

6 Frequently Asked Questions about “Can photovoltaic batteries be mixed ”

Can I mix different batteries for solar panels?

Mixing different capacity batteries for solar panels is not recommended. This is because batteries' performance levels change as they age. When the stronger battery in the system compensates for the weaker ones, there's a risk of overheating which degrades your batteries faster and increases the risk of fire.

Can a battery be mixed together?

There are ways to mitigate the issues but you should really not mix batteries that aren't built together and at the same time. You should only use "batched" batteries, this is true of all battery cells and it is especially critical and true of a Lithium installation.

Should I mix a new battery with an old battery?

Different age mixing is not recommended because the battery's needs change as they age, therefore it's better to start with like batteries of equal capacity, avoiding parallel strings if possible or keeping them to a minimum no more than three. So define type, legs and if you intend to mix new with old.

Can I put a 6V battery in parallel with a 12V battery?

Warning: The batteries must be of the same voltage range. Don't put a 6V battery in parallel with a 12V battery. The lower Amp Hour battery will take in charge faster and drain faster when in use. The bigger battery will in turn try charging the smaller battery leading to some energy loss but your system will still run.

Should I mix battery chemistry and design?

If your battery chemistry and design are the same, you could consider mixing and move on to the next stage of our guide unless your batteries are Lithium technology based. All these batteries have internal control circuits (Battery Management Systems) that will either shut down or fail if the capacity discrepancy is too high.

Is it OK to mix battery brands?

The batteries have the same chemistry, voltage, and amperage, but are from different brands. I'm looking into ExpertPower now and maybe later on expanding my system with Battery born. Is it ok to mix battery brands in this manner? A cursory search of a few brands' warranties doesn't indicate any issues with mixing brands.
