Normally a 12 volt lead acid battery will show approximately 12.6 volts when fully charged (open cell voltage without surface charge) and around 11.9 - 12.0 when nearly discharged. With a surface charge, you can see readings upwards of 13.2 or so right after a charge and for several hours afterward if left disconnected.
Free QuoteThe battery was comprised of 12 parallel strings of 118, 5-cell, lead–acid modules; thus, each string consisted of 590 cells, the battery consisted of 1416 modules or 7080 cells, and the nominal battery voltage was 1180 V. The battery used a flooded, copper-stretch-metal technology; the latter feature enhanced the negative-plate conductivity, which, in turn,

Free QuoteThe actual resting voltage, or the voltage a battery will settle at 12-24 hours after being removed from the charger, is closer to 2.1 volts per cell, or about 6.4 volts for a 6v battery, and 12.7 volts for a 12v battery. These numbers assume 100% healthy cells, and may vary a bit lower for older batteries.

For a lead-acid battery, it's charging at 14.4V, but once fully charged, the resting voltage of the battery itself will drop back down to about ~12.7V. This depends on battery chemistry, and other factors like ambient temperature. Li has a more flat voltage curve, so voltage is not as good an indicator of charge as for lead-acid.
