We've been experiencing a rash of bad Duracell batteries, both 9 volt and AAA. Mostly badly leaking pre-expiration date Duracells, which have ruined some electronic devices and now one actually blowing up.
Kirkland (Costco) was recommended, but Amazon reviews show they are just re-labeled Duracell and leak and fail as much.
Removing ALL Duracell batteries from all our equipment now and probably replacing them with a more durable brand, or just leaving the batteries out all-together.
So far using EverReady batteries has been okay; no failures yet, but searching for the "most reliable AAA" batteries.
