Replaced battery in kitchen smoke alarm. Tested, all good. Put back, but it beeps every minute like the low battery warning. 10 minutes later its fine. Odd?

When I had this I changed the battery in another smoke alarm that doesnt have low battery beep, now it does. 

Bad battery batch or do they need to settle in for an atmosphere change? I guess they went in 2010 when the house was built. 

Old and new batteries are Eveready Super Heavy Duty.
