Current capacity of batteries wired in parallel
Parallel. The capacity adds up. If the batteries are identical, then no more comments are needed. In general, the batteries have to have the same chemistry and voltage. E.g. connecting a lithium-ion battery in parallel with lead-acid battery is a bad idea. Series. The voltage adds up. The capacity is equal to that of the smallest battery.
parallel
You can coarsely determine their state of charge by measuring their quiescent voltage -- i.e. their voltage when you haven''t tried charging or discharging them in the last few hours.. Lead-acid batteries (and, well, a lot of batteries) become less charge-efficient as they get nearer to top-of-charge. As such, if they are reasonably near, they will tend to self-balance.
Interfacing Lead Acid batteries with inverter
No, inverters using lead acid only know voltage, current, temperature, and time. Some models may be better than others at guessing when an equalization charge (for FLA) should be performed. What you can do is periodically check voltages of individual cells (if terminals available) or of 6V or 12V batteries.

If a large battery bank is needed, we do not recommend that you construct the battery bank out of numerous series/parallel 12V lead acid batteries. The maximum is at around 3 (or 4) paralleled strings. The reason for this is that with a large battery bank like this, it becomes tricky to create a balanced battery bank.

How much current should a parallel battery have?
For a single parallel battery, maintain a charge and discharge current of 25A each. As you add more batteries, increase the current values in increments of 25A. Deviating from these specified current values, whether exceeding or falling below them, can accelerate wear and compromise the overall lifespan of your battery setup.
How long does a lead acid battery take to charge?
Last example, a lead acid battery with a C10 (or C/10) rated capacity of 3000 Ah should be charge or discharge in 10 hours with a current charge or discharge of 300 A. C-rate is an important data for a battery because for most of batteries the energy stored or available depends on the speed of the charge or discharge current.
What happens if a battery is connected in parallel?
If we connect the positive terminal (+) of battery to positive and negative (-) to negative terminal. Then the batteries configuration would be in parallel.
