What is enough?
And I prefer the ability to just pop a new battery in than sit around waiting for it to recharge. And if it were a case of rechargeable batteries, well I know nothing about electronics in this regard, but I have noticed that with mice, there seems to have been a large shift away from rechargeable, in favour of disposable, and as I say, I can't comment on how well rechargeable batteries would do, but these mice can now get a year on a single set of batteries. I just don't see the issue. Keep a spare and pop it in when the tome arises.
