ANSMANN X-POWER AA 4PK - AA

Kept my digital camera running for an entire afternoon of shooting, which is way better than the two hours I got from the no-name packs. These have a nice long shelf life too, so I don't worry about them dying in the drawer.

My TV remote chews through batteries, but these have lasted over three months so far without the voltage dropping. The ten-year shelf life is a nice safety net for the spares I keep in my camping bag.

These are perfect for my guitar effects pedals—I went through a full band practice without any noticeable power drop. The price for a four-pack is fair, though I wish the packaging was a bit easier to open.
