In that way, you will end up operating the battery at or near a state of discharge, which risks further sulfation. It''s also hard on an alternator to do that since they aren''t designed to charge batteries from a state of full discharge. Alternator voltage regulators also require a 12-volt input to operate properly.
The voltage of a battery is directly related to its state of charge (SOC). As a battery discharges, its voltage decreases. Conversely, as it charges, its voltage increases. A fully charged 12V battery should have a voltage reading between 12.6-12.8 volts. At this voltage level, the battery can provide its maximum power capacity.
Learn three easy steps to check your battery at home: inspect, voltage, and load test. Find out the signs of a bad battery, the causes of sulfation, and how to prevent or reverse it.
