The sleek, compact Apple Battery Charger is all about efficient charging. It's optimized for Apple-supplied batteries, but it works with AA NiMH batteries from other companies, too. And with a feature that automatically reduces its power intake once your batteries are fully charged, the Apple Battery Charger is one of the most energy-efficient rechargeable battery solutions available.
It comes fully loaded. And then some.
Each Apple Battery Charger comes with six NiMH batteries — two for your keyboard, two for your mouse or trackpad, and two for charging. Not only do these high-performance batteries have up to a 10-year lifespan(1), they also hold a charge for an incredibly long time. So you always have power when you need it.
More charges. Less waste.
The Apple Battery Charger has one of the lowest standby power usage values — or "vampire draw" — of similar chargers on the market. That’s the energy that most chargers continue to draw even after their batteries are done charging. Unlike other chargers, the Apple Battery Charger senses when a battery charge cycle is complete and automatically reduces the amount of power it uses to 30 milliwatts — more than 10 times better than the industry average.(2)
Better for the environment.
With the Apple Battery Charger, you no longer have to buy or hassle with the disposal of batteries every few months. The charger works quickly and efficiently. And once your batteries are fully charged, it draws less power than many similar chargers on the market. (2)
