    Always a good idea to buy batteries where you know the stock is rotating regularly. The same batts in a drug store might sit on the shelf for months, but at Best Buy they're moving out.

    Date showed new on the box...batteries weren't about to expire. We replace our fire alarm batteries twice a year. After batteries are taken out of alarms, we put in other toys for the kids.
