Battery voltage charts describe the relation between the battery's charge state and the voltage at which the battery runs. These battery charging voltages can range from 2.15V per cell to 2.35V per cell, depending on the battery type. You can check or read a battery's voltage using a multimeter.
The 6V lead-acid battery state of charge voltage ranges from 6.37V (100% capacity) to 5.71V (0% capacity). 12V Lead-Acid Battery Voltage Chart (2nd Chart). The 12V lead-acid battery state of charge voltage ranges from 12.73V (100% capacity) to 11.36V (0% capacity). 24V Lead-Acid Battery Voltage Chart (3rd Chart).
6V Lead-Acid Battery Voltage Chart (1st Chart). The 6V lead-acid battery state of charge voltage ranges from 6.37V (100% capacity) to 5.71V (0% capacity). 12V Lead-Acid Battery Voltage Chart (2nd Chart).
The total capacity required for the battery pack, measured in ampere-hours (Ah). The capacity of a single cell, typically measured in ampere-hours (Ah). Cells connected in series to increase voltage (total voltage = sum of cell voltages). Cells connected in parallel to increase capacity (total capacity = sum of cell capacities).
Charge Voltage – The voltage that the battery is charged to when charged to full capacity. Charging schemes generally consist of a constant current charging until the battery voltage reaching the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small.
» Electrical » Cells Per Battery Calculator The Cells Per Battery Calculator is a tool used to calculate the number of cells needed to create a battery pack with a specific voltage and capacity. When designing a battery pack, cells can be connected in two ways: in series to increase voltage, or in parallel to increase capacity.
