What voltage is required to charge it? A: A 12V car battery can be safely charged over a range of voltages. It needs at least 12.9 volts to charge, but at this voltage the charge rate of an automobile battery is very slow. A car battery can be charged safely at high voltages as long as the battery is not fully charged.
Can you use a 12 volt battery charger to charge a car battery?
Many will start out at 750 mA – 1.5 A and then drop down to a very low rate once the battery is full. You can then just leave them on your battery. YES, you can use 12V DC power supply for charging car battery. After charging for 18 hours, check battery voltage.
How long does it take to charge a car battery with a 12V charger?
about 12 hours

What voltage should I charge a 12 volt battery?
12.6V volts or above – Your battery is healthy and fully charged. No further action is required. 12.5 volts – Your battery is at a healthy state of charge, but we’d recommend re-checking it within a few days to ensure the voltage hasn’t dropped any further.
Can I use a 12V power supply on a 24V?
If you’re trying to go the other way and connect a 12V power supply to operate 24V LED strips, unfortunately, you are out of luck. You’ll need to purchase a transformer or voltage booster, or, more straightforwardly, a 24V power supply.
Can you jumpstart a 24 volt system with a 12 volt?
On a two battery system, you can jump from the 12 volt system, connecting to the ground side battery in the 24 volt system. When you do that, you are tapping into the middle of the 24 volt setup and when the truck’s charging system takes over, you won’t get a 24 volt surge into the 12 volt system.
Can I jump a 12 volt battery with a 24 volt battery?
Yes you just connect your leads to ONE of the big rig’s 12v batteries (they have 2 x 12v batteries in series to give 24v), then crank it over.
Can I charge a 12V battery with a 15v charger?
