We've got a thing for Sanyo's Eneloops. Had it ever since Sanyo released us from the clutches of underperforming NiCad and NiMH batteries about five years ago. Its latest AA and AAA batteries can be recharged about 1,500 times, that's about 3 years of continuous service and 500 more cycles than competing rechargeables, according to Sanyo. The batteries also feature a low self-discharge rate so they remain usable even after they've been charged and stored in a drawer. In fact, an Eneloop will maintain about 75% of its charged power even after three years. Impressive, we know, and the reason they come pre-charged from the factory for immediate use of out the box. And compared to disposables, they're as good for the environment as they are for your wallet over the long run.
