6 Frequently Asked Questions about “Lead-acid batteries have voltage limits but not current limits”
What voltage does a lead acid battery charge?
A lead acid battery charges at a constant current to a set voltage that is typically 2.40V/cell at ambient temperature. This voltage is governed by temperature and is set higher when cold and lower when warm. Figure 2 illustrates the recommended settings for most lead acid batteries.
What is the maximum charging voltage for a battery?
That generally agrees with charging voltages imprinted on some of the batteries. For example: Notice that initial charging current for Standby Use (lower charging voltage) has no limit. Charging current for Cycling Use (higher charging voltage) has a limit at 0.3C Amps. Without the limit the battery would pull 2C amps at that charging voltage.
Can a lead acid battery be charged at a full charge?
Test show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.
What is the charging current limit for a car battery?
Charging current for Cycling Use (higher charging voltage) has a limit at 0.3C Amps. Without the limit the battery would pull 2C amps at that charging voltage. In the vehicles, the starting battery, the system load, alternator w/ regulator are all wired in parallel. AFAIK, there is no current limiting between the alternator and the battery.
What is a lead acid battery?
Lead acid batteries have the characteristic that their voltage comes up quickly and then the current tapers off. They are extremely tolerant of charging systems built around the voltage levels shown on the label. FYI: I use a standby voltage of 13.2V on my float charger but it also has temp compensation. Here is the curve explaining it.
What temperature should a lead acid battery be charged at?
If the float voltage is set to 2.30V/cell at 25°C (77°F), the voltage should read 2.27V/cell at 35°C (95°F). Going colder, the voltage should be 2.33V/cell at 15°C (59°F). These 10°C adjustments represent 30mV change. Table 3 indicates the optimal peak voltage at various temperatures when charging lead acid batteries.
