While most would agree that using rechargeable batteries is already better for the environment than using single use alkaline batteries, Apple has designed a battery charger that presents an improvement over traditional battery charging stations.

With a power-management system that cuts the power when the batteries are fully-charged, the new battery charger nearly eliminates the so-called “vampire draw.” While similar chargers for nickel-metal hydrite rechargeables on the market may draw up to 315 milliwatts on standby, Apple’s charger has reduced this down to 30 milliwatts, thus wasting less energy on standby.

Aside from the battery charger, Apple has also introduced its own brand of rechargeable batteries which are also designed for more energy-efficient use. These batteries are made to retain a high charge capacity so as to make them last longer than most other rechargeables. This way, users of the batteries would not have a need to buy new batteries every few months. According to Apple, their reusable batteries can serve up to 10 years, based on a designed life cycle and anticipated user scenario. Apple also demonstrates that the batteries have a low self-discharge rate as well; given the scenario of these batteries stored at room temperature, they are estimated to retain about 80 percent of their original charge.

Although designed to work best with the batteries supplied by Apple, the new battery charger is also compatible with other AA-sized nickel-metal hydrite rechargeable batteries on the market. With a removable AC plug, the charger can also be used internationally with different plugs suited for different outlets around the world.

Currently, the charger kit, including six AA-sized batteries costs $26. As it is built for long-term use, this new battery charger from Apple is definitely a step towards making simple staples of technology take the green route. I believe that Apple is definitely going in the right direction with improving simple technology and making them more energy efficient. It could extend the rate of battery exchange from months to years.
