The terminal voltage of the Lead-Acid battery should be within a certain range such as 12 to 13Volt. In the event that the battery voltage lessens beneath 10 volts for a long period, the battery won’t accept any charging current. Thus, if the terminal voltage surpasses over 14 volts, the battery will be devastated.
