Granted, I've never heard of the battery dying (yet)
True, but the battery is rated to last for a full 500 charge cycles--meaning, 500 cycles from completely drained to completely charged. Since I've had mine, a full charge lasts approx. 10 - 12 days. So, even if avg. usage time equals "only" one week, that equals 500 weeks of usage. Not saying the battery WILL last that long, but I've never had problems w/ Logitech when it comes to hardware replacement in the event it last significantly shorter than that. Hell, I can't see many people who would spend that much on a mouse using it for more than 2 - 3 years max. anyway.
