Yes! As of a couple weeks ago, Apple quietly released a handy AA Battery Charger, accompanied by six batteries.
The charger itself mimics a laptop MagSafe power block, but is about a tenth of the size. The battery charger also uses much less power than a typical charger; it will sense when the batteries are fully charged and slow the current being drawn, known as “vampire draw.”
The batteries are also designed to last years without losing much of their charge. Apple claims they retain 80% of their charge after sitting a full year in a drawer. They also say the service life of the batteries should be closer to 10 years!
With six batteries and a very compact charger, its $29 price tag seems very reasonable to keep all your gadgets running for years to come.
