For instance, a weak battery may have a voltage reading of less than 12.2 volts, while a fully charged battery may have a voltage reading of up to 12.8 volts. Voltage and State of Charge The state of charge of a car battery is a measure of the amount of electrical energy stored in the battery.
BU-804b: Sulfation and How to Prevent it
I have a question: John Fetter sugested a method to see if a battery is fully charged: "If you want to know if a lead-acid battery is fully charged or not, simply put it on a C/50 charge and watch the voltage. The voltage of a fully charged battery will rise to a plateau which will be in the region of 2.55 to 2.65 volts per cell.
BU-403: Charging Lead Acid
The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage charge methods, the charge time can be reduced to 8–10 hours; however, without full topping charge. Lead acid is sluggish …
Charging of lead-acid batteries
The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries. With higher charge current s and multi-stage charge methods, the charge time can be reduced to 10 hours or less; however, the topping charge may not be …
