Can You Use A Battery From One Car In Another. Empty the battery cells Until now you did not need to remove the vehicles battery. Do understand if you wanna replace that battery it is a special AGM cell battery and cant be bought too easily.
If its very large then the 12v battery will not charge it to even 9 volts and you can then connect the 9v battery and charge it to 9v. If you have a spare 12V battery from your portable drill you can carefully tape two large screws to the batterys terminals and then attach jumper cables to the drills battery and then the car. Attach the positive or red lead to the positive terminal of the dead battery and the other positive lead to the positive terminal of the good battery.
Do you want a new battery for your car but are unsure which one to get.
With this type of charger you dont need another car to help you recharge the battery. Having the appropriate battery also ensures that the batterys lifespan is maximized. The good news is that large 12v batteries make excellent buffers against power issues that might otherwise cause damage. Dont get stranded.
