Changing Battery While Car Is Running. While its running the battery was removed the engine kept running and my battery was reinstalled. To be clear I realize the battery isnt needed to power anything while the car is running at low load -- thats not the issue.
So can I keep power flowing by connecting a charger to the battery cables behind the terminals. The mission of the alternator is to charge the battery while the car is running. In theory if your alternator is providing adequate power to the car while charging the battery then once the car is started disconnecting the battery should not cause the engine to stop running.
Then I can carefully remove the terminals from the battery while.
While its running the battery was removed the engine kept running and my battery was reinstalled. Any smart battery charger on the market can safely charge your car battery while connected. Time to replace the OEM battery on my 2010 Escort. I went in to autozone again today and one of the employees told me that a way I can check if the alternator is good is to turn the car on and then disconnect the battery while its running.
