How do you know when a 12V battery is fully charged? A fully-charged 12-volt battery, allowed to “rest” for a few hours (or days) with no load being drawn from it (or charge going to it), will balance out its charge and measure about 12.
6 volts between terminals.
When a battery reads only 12 volts under the above conditions, it’s almost fully depleted.
Can I leave car battery charger on overnight? Even though there is no risk of overcharging with the use of a high quality charger, the battery should not remain connected to the charger for more than 24 hours. A full charge is usually achieved by charging overnight. Even after a deep discharge, some chargers enable at least partial reconditioning of the battery.

What happens if you charge a 12 volt battery with 24 volts?
If you just plug a 12 volt a battery into a 24 volt charger it will die in a matter of hours. Most 24V chargers are switchable between 12v and 24v, but assuming you are connecting a 24v only charger or a 12/24v charger switched to 24v, then you will blow the fuse in the charger.
Can you charge a car battery with a 12 volt charger?
Although car chargers are known as “12V Car Charger”, they in fact output more than 12V – typically 13.
8V or higher and may contain electronics to regulate charge current depending on the battery’s terminal voltage, so if the charger you intend to use outputs regulated 12V, then no, it won’t charge a car battery.
Can I charge a 12 volt battery with a 24 volt charger?
You cannot use the 12V charger directly to charge a 24V battery. To do the task you will need a boost converter capable of generating output voltage greater than 24V. Boost converters step up the voltage, keeping the input and output power constant.
