My sister and her bf moved in with us and are constantly using our car to jump start their own car (and I mean almost every day, sometimes more than once) and ever since then our lights have been flickering and now our car hesitates to start… I’m trying to figure out if this is because of the jumping or because of something else.
It’s been like a month and a bit of this.
Please any help is appreciated!
No but it will drain the battery more than it’s recharged most of the time.
Once you draw on your battery at low enough charge, THAT will damage and break it.
Batteries will last like ~50 years and longer if charged correctly and maintained.
The reason you have to replace the em is you don’t usually drive far enough and long enough to properly charge it after starting the vehicle.
However the alternator does keep it charged enough to last 5-10 for most people.
Then it dies on an unusually cold winter, or in your case from jump starting another car too many times.
