Yeah, it's unbelievable - I bought my trackpad about a month ago - and I have just checked, I have 87 % life left in the batteries, and it stays on 24 hrs a day !!!!!!!!!
Holy cow, if only cell phones were as frugal as this trackpad on batteries
I thought I would need to recharge the batteries often, so I bought two (2) recharge kits - that is 2 chargers and 12 rechargeable batteries !!!!! the spare batteries are charged and waiting to replace the ones in the trackpad....but at this rate I will only need to change them out in 2011 !!!!
