Good luck. And do be cognizant of how you’re parked in a garage or a tight parking space when having battery issues.
I say that because our cars can’t be put into neutral easily if you need to jump start the vehicle…because it needs power to be put into neutral. If you’ve pulled into the garage (forward) then the jump start terminals in the engine bay may not be easily accessible and you shouldn’t jump directly to the battery…so in low battery situations, you may want to back into your garage so in case you need a “jump” to start the car, you can pop the hood to quickly access the jump start terminals in the engine bay.
In your case, you’re in a better situation since you do have a battery charger/tender.
