Eneloop AA 4-Pack with Charger | $15 | Amazon
Graphic: Shep McAllister

Rechargeable batteries only really work if you have...a charger. $15 today gets you four of our readers’ favorite AAs, plus a charger that can accommodate them and rechargeable AAAs. Add in some of Eneloop’s C and D spacers, and it’s effectively a universal charger.

Today’s price is the best we’ve seen all year, but Eneloop deals rarely last long.
