I bought an Apple-branded set of rechargeable AA batteries with included charger a couple of years ago, and it's served me faithfully. At least until now. I use them for my Apple BT Keyboard, Apple BT Trackpad and Apple Magic Mouse. While the batteries on my Keyboard and Mouse can last for months without recharging, I've noticed the batteries of my Trackpad required charging more often (which they should; I use the Trackpad the most, and I understand it's sort of a power hog), but lately it's gotten to the point where I have to charge it every week or so, from every six or seven weeks before. It's becoming a pain now. I charged the Trackpad's batteries on Jan. 1, but now, on the 8th, it's telling me it's down to below 20% again and is asking to be recharged. It might be stupid to ask this, but do they really degenerate this much? I was expecting a few more years of service from them (well, at least for the Trackpad batteries—the Keyboard and Mouse ones are still really good). Maybe I have a messed-up Trackpad?
