Here’s a very rough table showing what charge percentages may apply if your fully charged voltage is 12.5 volts. What voltage is needed to be able to start my car?
What happens if a battery is discharged after removing a load?
When removing the load after discharge, the voltage of a healthy battery gradually recovers and rises towards the nominal voltage. Differences in the affinity of metals in the electrodes produce this voltage potential even when the battery is empty. A parasitic load or high self-discharge prevents voltage recovery.
What is battery discharge testing?
Battery discharge testing, also known as battery load testing, is a process that test battery health statement by constant current discharging of the set value by continuously the discharge current from a fully charged state and then measuring how long the battery lasts.
What is a normal battery voltage?
We noted that 12.6-12.7 Volts is the normally voltage for a fully charged battery, and showed which voltages correspond to which approximate charge % level. Be aware with analysing voltage – it doesn’t show the health of the battery per se, it just shows how much charge is in the battery at the moment you measure.
What percentage of a battery is fully discharged?
Batteries are seldom fully discharged, and manufacturers often use the 80 percent depth-of-discharge (DoD) formula to rate a battery. This means that only 80 percent of the available energy is delivered and 20 percent remains in reserve.
