Can two 12V batteries of different capacities be charged in parallel

As for running two batteries in parallel to power a load, this does come with some dangers and drawbacks, especial if one cell in one battery goes short circuit (rare, but happens), the situation is not good in the parallel configuration as the other battery will discharge with all its might into the other battery since the voltage just dropped.

6 FAQs about [Four lead-acid batteries are charged in parallel]

Can a lead acid battery be connected in parallel?

In theory it is OK to connect them in parallel with two conditions: Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged.

Can You charge a lead-acid battery in parallel?

Most lead-acid batteries charge at a constant 14 4 volts, so charging several in parallel is really just a charge-current issue. If the charger cannot supply enough current it will likely lower the charge voltage to protect itself.

Can a lead acid battery be voltage charged?

Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged. The power supply is capable of maintaining the fixed float voltage.

What happens if you charge a rechargeable battery in parallel?

When connecting rechargeable batteries in parallel, the charged batteries will attempt to charge the discharged one, draining themselves and wasting energy. This is because the stronger battery would charge the weaker one.

How do you charge a lead-acid battery?

Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged. The power supply is capable of maintaining the fixed float voltage. In practise, I think it's a good idea to put at least a diode in series with each battery just because stuff happens.

What happens to the voltage when batteries are connected in parallel?

The basic concept is that when connecting in parallel, the voltage remains the same. You add the amp hour ratings of the batteries together, but the voltage stays the same. For example: two 6 volt 4.5 Ah batteries wired in parallel are capable of providing 6 volt 9 amp hours (4.5 Ah + 4.5 Ah).
