What is a Good Battery Voltage for a Car? Measuring the voltage of your car battery can help you figure out how fully charged it is. With the engine running, the optimal automobile battery voltage is between 13.7 and 14.7V. You should receive a reading of 12.6 volts with the engine turned off. Low or bad battery voltage
Get PriceThe result is a true 24V battery pack that''s: a) much smaller than the 24V packs of old, and b) mated to a true 24V tool. And that''s the real news here—these tools are running at 24 volts as well—so they''re literally making use of the additional voltage and entering that into the equations for power, torque, and run-time.

Get PriceFirst a few basic lead battery charging rules. Charging a 12 volt lead-acid battery at over 14.4 volts will cause it to boil or out gas. The battery will take a higher voltage for a short term if it is cold. So a higher voltage will work for a few minutes until the battery warms up.
Get PriceEven though a typical lead-acid battery is considered fully charged at 12.6 volts, many of the early smart Honda systems were designed to see 12.4 volts, or 80% state-of-charge, as perfectly normal and the …
Get PriceStandard car batteries are listed as 12-volt batteries. However, this is rounding down, as a car battery should have a "resting voltage" – which is to say, the amount of voltage it has when it''s turned off – of 12.6 volts.
