What happens if you put old battery back in?


Haven't tried it. Would that offer any diagnostic clues? Guess it would show if the new battery is a dud. Is this common now? Seems like it was a year ago.


"new" battery just means it is new to you.. the battery may have been manufactured a year ago and sat on a wharehouse shelf before being shipped to you, batteries degrade slowly whether being used or not.
