I’ve always been told by battery and hearing aid manufacturers to wait one to two minutes after peeling off the tab before inserting a battery into a hearing aid.  It seems like a smart young man from Minnesota has figured out with his audiologist that waiting 5 minutes before inserting the battery can increase battery life up to 80% giving up to 2 extra days of use!  Can’t hurt to try, let me know how it works for you!
