Duracells seem to work well for me and i anticipate nothing different. My best use for these batteries is the tv remote. No matter how many trips they take, they just go right back to work - forever!

Expiration date 2029 (weren't supposed to expire for another 7 years). These batteries are 2-3 years old. Others are totally shorted out.

The blister pack is just so you can see what's inside but then it ends up in the landfill. Luckily, i never had one burst open like another reviewer here - sounds very dangerous. Duracells leak and leak.

The package of batteries was opened, repackaged and taped closes. There is no way the packaging was opened during shipping.
