Mixing different lead-acid batteries

Let’s suppose you have 3 different 12V batteries, wired in parallel to supply 12V power to your RV. They can have different capacities on account of size or age, but the same chemistry (e.g. all flooded lead acid or all AGM). Before you start charging, the voltage across each of them is the same–even if one is fully.

6 FAQs about [Mixing different lead-acid batteries]

Can you mix AGM and lead acid batteries?

Yes, you can mix AGM and lead acid batteries, but it’s not recommended. AGM batteries are designed to work with a charging system that provides a steady flow of current, while lead acid batteries are better suited for a charging system that provides a pulsed current.

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.

Can you mix lithium iron phosphate and lead acid?

This means you can’t mix lithium iron phosphate with lead acid, Lithium Iron Phosphate with Lithium-ion, or a flooded lead acid with an AGM lead acid battery. 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.

Will lead acid batteries sulfate?

Lead acid batteries will sulfate while lithium batteries might survive. You can theoretically get away with this if you design your system perfectly. After all, the only problem here will be the different batteries will charge and discharge at different rates. Warning: The batteries must be of the same voltage range.

How does a lead acid battery bank work?

Charge will flow from one battery to the other two until they’re balanced. With a lead acid battery bank, the internal resistances are limiting to a point that you don’t have to worry about arcing or your battery cables overheating when you connect them (not the case with lithium-ion banks).

Is mixing up battery capacity a bad idea?

Today we are going to look into the consequences of mixing up battery capacities and if it is something you should do. Quick Answer: No, its not a good idea. You will either get less overall capacity, damage the batteries, or shorten their lifespan by not charging and discharging the different batteries to the right voltages.
