Sony NP-FM500H InfoLithium Battery

Finally a battery that doesn't develop memory effect — I can top it off whenever I want without worrying about degrading the cells. It's small and lightweight too, so it doesn't make my camera feel unbalanced during long shoots.

I've been using this rechargeable battery for weeks now and it's great how it holds a charge even after being stored for a while. The lack of memory effect is a real plus, so I can top it off anytime without worrying about damaging it.

Finally a battery that doesn’t lose its charge if I set the camera down for a few days — that memory effect was driving me crazy. It’s small enough to keep a spare in my bag without weighing me down.
