The charger has a white design, with a small indicator light on top that glows amber while the batteries are charging, and green once they are charged. It can charge two NiMH batteries at once,[2] and takes five hours for a full charge.[5]
Apple's main marketing claim for the product was that the charger had a standby power draw of 30 mW, compared to an industry average of 315 mW.[2][6][7]
According to Apple, these batteries were designed to have a service life of up to ten years and retain 80% of their capacity even after being stored for a year.[10] Engadget says the Sanyo Eneloop batteries are able to retain 75% of their charge after three years.[8]
Reception
Engadget criticized Apple for selling their charger and six batteries for $29 when Sanyo sold a charger and eight batteries for the same price.[8]SuperApple noted that Apple's then-current wireless peripherals used two AA batteries, but older Apple Wireless Keyboards used three; Apple's charger could only charge two at once.[5]
