A practical understanding of lead acid batteries
Be sure you look at a table that correlates resting voltage against SoC and not the voltage under load. If you see a table with 10.8 volts at 0%, you are looking at a table for under load voltages. A battery at 10.5 - 10.8 volts at rest is probably damaged. A lead acid battery should never be below 11.80 volt at rest. ↩
What Should A 12 Volt Battery Read When Fully Charged?
A 12V battery should be considered discharged and no longer good if the voltage level drops below 10.5 volts. At this level, the battery is deeply discharged and may not be able to hold a charge anymore. Is a reading of 12.3 or 13.2 volts indicative of a healthy 12V battery? A reading of 12.3 volts indicates that the battery is only partially ...
Battery drops to 10.5 volts after charging
If you lose one cell, it will drop it down ~2vdc, which puts it right down in the arena of 10.5vdc. A direct short inside of a cell will allow electrons to pass through the short instead of raising the voltage, which is the reason you''re still reading the 10.5vdc. Anyway, long story short: you need to replace your battery.
