How to Recondition Lithium-Ion Batteries
If your 3.7v lithium-ion battery''s voltage drops to below 1.5volts, it''s dead. Most lithium-ion batteries have a nominal voltage of between 3.7v-4.2v. The minimum safe voltage is usually around 2.7v, and the manufacturers normally indicate it on the manual. When the battery goes below the indicated minimum voltage, it''s dead.

12 Volt Battery Voltage Chart
For example, a fully charged 12-volt lead-acid battery will have a voltage of around 12.8 volts, while a partially discharged battery may have a voltage of 12.2 volts or less. To get an accurate reading of a battery''s state of charge, you need to use a battery tester or multimeter that takes into account the battery''s type and voltage characteristics.
How to Diagnose a Bad Car Battery – Practical Mechanic
A car battery voltage should be between 13.7 and 14.7 volts when the car is running, indicating that alternator is charging the battery and it can sustain the voltage. The following table gives some approximate voltages associated with various charge levels.
Testing for Battery Sulfation/How to Desulfate a Battery
If the voltage is less than 12.4 volts (for a 12 volt battery) or 24.8 volts (for a 24 volt battery), which is typically 75% of charge, the battery may be too heavily sulfated to be fully recoverable. If voltage is 12.4 volts (for a 12 volt battery) or 24.8 volts (for a 24 volt battery) or higher recovery can be expected, given sufficient time.
