Charging a battery with jumper cables using another car will work just fine. It doesn’t matter if the battery is in or out of the car. Doing this implies that the car doing the charging is running so that the alternator is applying a proper charging voltage across the battery terminals of both batteries.
Can you charge a battery with another car battery?
Jumper cables can supply power via a functional battery from another car. Keep a set in your vehicle. Connecting your car’s battery to another car’s battery with jumper cables is a common way to recharge a battery.Attach the other red clip to the positive terminal on the battery that needs a charge.
Can you charge a 12V battery with another battery?

What happens if you connect a battery to another battery?
When connecting batteries: Never cross the remaining open positive and open negative terminals with each other, as this will short circuit the batteries and cause damage or injury. Be sure the batteries you’re connecting have the same voltage and capacity rating.
What happens when you connect a battery to another battery?
Connecting a battery in parallel is when you connect two or more batteries together to increase the amp-hour capacity, with a parallel battery connection the capacity will increase, however the battery voltage will remain the same.
Can you charge 2 12v batteries in series with a 12v charger?
Charge more than five batteries by connecting one 12-volt battery charger across each battery in the series, as if each battery were the only one being charged. Charge all the batteries at the same time.
What happens if you charge a 12 volt battery with a 24 volt charger?
No, you are not supposed to charge a battery of 12volts with a charger of 24 volts, tremendous heat will be generated and the battery may explode.
Can you charge a 12 volt battery with a 15 volt charger?
If you use a 15 volt charger on a 12 volt battery it will work no matter what type of battery it is. But charging will be very fast, the battery will get hot, depending on the type it could get very hot or even explode! So if you do this, that is, use the 15 volt charger on the 12 volt battery.
Can I start my car with a 12 volt battery?
so yes you can start a car with 12 volts, just keep in mind that those 12 volts will need a whole lot of amps pushing them. some cars can start using lower amperage than others and that depends on the number of cylinders a car has and the compression ratio of those cylinders.
Do I need to disconnect both battery terminals when charging?
Always disconnect the negative (usually black) lead first and reconnect it last, otherwise you could end up getting a nasty shock when you touch the positive terminal. The terminals are usually connected to the battery by a clamp, which is loosened or tightened by a bolt on the side.

Can you connect two different batteries together?
You cannot connect batteries of different amp-hours in series with good results. We strongly recommend you DO NOT attempt to mix battery sizes (amp-hours) and connect together. Due to differences in battery management systems and battery cell counts, there may be a charging and voltage discrepancy between batteries.
Do dual batteries have to be the same?
Yes, you’ll need two batteries for the best dual-battery setup, and you’ll need two different kinds of batteries. The primary unit should remain a typical starter battery.
Is it OK to use a 12v charger for charging each one of two 12v batteries connected in series without having to disconnect them from each other there is no load connected?
Do not mix and match different battery voltages in the same battery pack. In this example the battery pack voltage is 12 volts which is exactly the same as each of the individual 12-volt batteries.
How do you charge multiple batteries with one charger?
An example method of charging batteries in parallel is to use one branch of the parallel circuit to charge each battery with a single charger. Connect the positive output of the charger to the positive terminal of the first battery, and connect that positive terminal to the positive terminal of the second battery.
