Is 12.3 volts a good battery?
Check the reading. A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.Jan 24, 2018
How many volts should my boat battery have?
Once fully charged, marine batteries should be held at a considerably lower voltage to maintain their charge - typically 13.2 to 13.4 volts. Higher voltage levels will "gas" the battery and boil off electrolyte, again shortening battery life.

What voltage is too low for a 12 volt battery?
12.0 volts or below - At 12.0 volts your battery is considered to be fully discharged or 'flat' and should be recharged as soon as possible. The lifespan of your battery will be severely affected if it remains within this voltage range for extended periods of time.
Whats a good battery voltage for a boat?
This should be between about 13.2 and 13.4 volts for batteries in good shape near a full charge. If the meter reads any higher, the batteries are really drawn down, and may be “dead” or dying. If the voltmeter reads more than 14.5 volts, you may have a problem with your charging system.Jul 25, 2016
