Apple’s new battery charger has very low “vampire draw” and reduces power when the batteries are charged. It comes with 6 high-performance AA NiMH, which they can last up to ten years. Plus, the batteries can sit in a drawer for a year and still have 80% charge. $29.99
Does it come in a version that doesn’t have the Apple-tax?
I’m getting my first Mac this weekend! Sure, it is old, but at least I’ll get to program for my iPhone.
