Hi all, The batteries which came with my trackpad recently just ran out and I replaced them with recyko brand rechargeable batteries. However, what I noticed is that their charge seems to drain super-fast. Where previously, the energizer batteries lasted almost 2 months, my new batteries have dropped by 5% after barely half a day's use! I know that well, being rechargeable batteries, I can simply rejuice them as necessary, but it seems quite extreme. The batteries ran fine on my other appliances like torchlights and video cameras, so I was quite surprised. Has anyone experienced a similar issue? What kind of batteries are you all using or would recommend?
