パナソニック エネループ 充電器 単4形1900mAH NiMH電池4本付き

I tossed out my old batteries that wouldn't hold a charge anymore, and these Eneloops still have 70% capacity after sitting in a drawer for five years. The charger handles both AA and AAA, though a full charge takes about 10 hours.

Finally a charger that doesn't let the batteries go dead after a few months of sitting—these still held 70% charge after over a year in a drawer. It's nice to swap them into my wireless mouse every couple weeks and not worry about them losing power.

Dropped my remote in a drawer for over a year and the eneloops still had plenty of juice, which is crazy for rechargeables. They charge slowly overnight but hold that 70% capacity after years of sitting around.
