Nobody likes an overachiever and the same goes for car parts. The second most important part of a car is the battery and sometimes it can be too energetic. Just like overcharging a phone, your car battery voltage can be too high. High voltage can be damaging to your battery and your vehicle. How do You Test Battery Voltage With a Voltmeter?
Up to this voltage and at normal temperatures, the battery will only gas very slightly. Above this, and it will gas increasingly with increasing voltage. This will damage your plates by causing flaking of plate material and shortening your battery's life. Gassing is undesirable. Note, by gassing, I don't mean boiling.
Turn on your voltmeter and make sure it’s set on the “voltage” setting. Place the red sensor on the positive terminal and the black sensor on the grounded (or negative) terminal. Check to see the reading and if it is over 12.9 volts, your battery may have excessive voltage. 12.6 to 12.8 is the ideal voltage level for your battery.
Charging a car battery for too long can lead to overcharging. For example, using a charger for more time than recommended can cause the battery to receive excessive voltage. Monitoring charging time is critical, particularly for manual chargers that don’t stop charging when the battery reaches capacity.
A regulated charger will hold the voltage to 13.5 to 13.8 volts once the voltage has peaked, to prevent gassing and overcharging, and the current will drop to almost zero in a healthy battery. Gassing due to overcharging also "uses up" the water in your electrolyte, and in sealed batteries will fairly soon ruin the battery.
Car battery overcharging happens when the voltage exceeds 14.7 volts, leading to overheating, corrosion, and potential failure or explosion. Regular maintenance and using smart chargers can help prevent this issue.
