6 FAQs about [Battery bank voltage difference is high]

Why is my battery bank not charging?

The battery bank may have reached the end of service life, or one or more cells or batteries have developed a fault: In case of series/parallel connection, disconnect the midpoint parallel connection wiring and measure the individual midpoint voltages during discharging to isolate faulty batteries or cells.

Why does battery voltage drop with load?

The greater this (non-load) internal resistance the more the battery connection voltage will drop with as load increases. It's more common with lead acid batteries to see larger voltage drop with load as they have a higher internal resistance than lithium chemistry batteries.

What happens if a battery bank is changed?

In case of a new battery bank the alarm is usually due to differences in the initial state of charge of the individual battery. If the deviation increases to more than 3% you should stop charging the battery bank and charge the individual batteries or cells separately.

Why do lead acid batteries have a higher voltage than lithium chemistry batteries?

It's more common with lead acid batteries to see larger voltage drop with load as they have a higher internal resistance than lithium chemistry batteries. But the resistance can also be due to poor external connections, or inadequately sized wiring, so always check those are good and are suitably sized for the load they are to carry.

How do you charge a battery bank?

Charge the battery bank. Measure towards the end of the bulk charge stage. This is when the charger is charging at full current. Measure the individual battery voltage of one of the batteries. Measure the individual battery voltage of the other battery. Compare the voltages.

Why are batteries interconnected?

Batteries are interconnected to increase the battery voltage or to increase the battery capacity or both. Multiple interconnected batteries are called a battery bank. When batteries are connected in series, the voltage increases. When batteries are connected in parallel, the capacity increases.
