What is your question?
auto and had the battery tested they said it was low but they couldn't check the alternator until it was off the car and they said for me to get a new battery first. The car starts and drives fine could it be a sensor?

do like pushrod said in answer #1 and forget about advance,they are just trying to make a sale on a battery.they could have charged your battery for you inside the store,maybe took 30 minutes,then they could have checked your alternator on your car after the battery was charged.
