Logitech’s New Mouse Lasts Three Years on One Charge

It may not be the best performing mouse if you're looking to frag all night, but the Logitech M525 does have one big thing going for it: longevity. Pop in two AA batteries, and you're set for years.

Like any battery claim, you can't take it as concrete—it'll be more than three years if you don't use it much, less than three years if you're above whatever Logitech considers average. But the bottom line is, you won't have to think about changing the batteries. Maybe ever. And for a wireless device, that's a rarity. Optical tracking plus 2.4 GHz wireless connectivity for $40 ain't bad either.
