Old school a full charged battery was 13.0 volts, 12.8 volts was 75% charged, 12.4 volts was 50% charged below 12.2 volts they need to be checked and probable replaced. At 12.4 volts batteries should be charged.
Sorry but that data is absolutely incorrect.
There is nothing wrong with my battery bank.
But thanks for the concern.
