BetterBattery Eco AA + AAA Combo Pack

Having both sizes in one pack means I'm not digging through a drawer looking for the right battery. The fact that they're fully recyclable is a nice bonus, and the delivery came right when scheduled.

Ordered the AA and AAA combo since I was tired of digging through the junk drawer for mismatched batteries. The packs are fully recyclable, which made me feel better about tossing the old ones, and having them show up on my doorstep without a store run was a nice bonus.

The carbon-neutral thing sold me, but honestly I'm just glad the pack covers both AA and AAA so I don't have to order twice. Dropped a set in my bike light and they've held up fine through a week of commuting.
