Can you mix different group batteries?

Can you mix different group batteries?

A: As chemistries and voltage vary across both battery types and brands, we recommend that you do not mix batteries. For best results, replace all batteries with the same brand, chemistry, voltage, and size when the device performance becomes unsatisfactory.

Can you run two different batteries in series?

Summary. In short, connecting batteries of different voltages in series will work, but damage will be done to both batteries during the discharge and recharge cycles. The more one is damaged, the more the other one will be damaged and both will need replacing long before needed.

Do batteries in series have to be the same?

Batteries connected in series must be as close to identical as possible, to make sure that the individual cells in each battery charge and discharge together and are ‘balanced’ (have the same voltage).

Can a 6V deep cycle battery ruin a new battery?

But your old battery isn’t going to ruin the new ones. It’s common in many RVs to make use of pairs of 6V deep cycle batteries wired in series. In a pair of 6V batteries in series, the voltages of each are not guaranteed to be the same as they are when wired in parallel.

What happens when you mix different types of batteries?

Each battery acts like a resistive load, and current will flow to the battery with the lowest resistance, or highest capacity, more than the rest. All of them will reach the end of bulk charging together, when they’ve all reached the same voltage (remember, they’re connected together–they have no choice!).

Can a battery be excluded from a new battery?

There’s absolutely no reason for an aged battery to be excluded from a battery for electrical reasons–only for space and weight would that make sense. Would a new battery have greater capacity than an old one? Sure. But the one you have is free while a new one isn’t.

What’s the best way to test battery capacity?

One of the easiest ways to test individual battery capacity is with a portable analyzer. If you only have 12V batteries, they’re pretty inexpensive, like for . If you have 6V batteries though, you’ll probably want one capable of analyzing an individual 6V batteries.
