But, for boost charging at a CP voltage of 14.4 to 14.7 for VRLA batteries, an initial maximum current of 30 to 40 percent of rated capacity in amperes is stipulated by most of the manufacturers (both flooded and VRLA type). A variation of ± 1 % on the float voltage value and ± 3 % for boost charge voltage are prescribed by most manufacturers.
If it drops to 11.63V, it is around 10% charged. These voltage values assume the battery is at rest with no load or charging. The values may differ somewhat under load or charge. But this chart provides a handy guide for translating voltage to capacity. ... Why Does Lead Acid Battery Voltage Drop Under Load? The internal …

State of charge of lead acid battery is the ratio of the remaining capacity RC to the battery capacity FCC [1]. The FCC (Q) is the usable capacity at the current discharge rate and temperature. The FCC is derived from the maximum chemical capacity of the fully charged battery Q MAX and the battery impedance R DC (see Fig. 1) [2]. (1) S …
Lead acid batteries, like all other types of batteries, have a varied voltage at various stages of charge. A 12V sealed lead acid battery, for instance, has a 12.89V at 100% charge, and when it drops to 11.63V, it is said to be at 0% charge. The good news is that lead acid battery state of charge (SOC) charts are available if you need to …
For example, a 12V lead-acid deep cycle battery at 100% capacity will have a voltage of around 12.7V, while a battery at 50% capacity will have a voltage of around 12.2V. By measuring the voltage of the battery and comparing it to the chart, you can estimate the remaining capacity of the battery.
