No way. The only sensor available to you is the low battery indicator
(if I remember correctly you can sense it via a system flag). Why do
use rechargeable batteries? Do you use a card reader *extensively*?
I replaced my Ni-Cad pack with ordinary alkalii batteries
when I stopped using my card reader. MUCH longer life. If you have an
old 41 which still has the connector for the never-released battery eliminator
you can save battery life by using a home-built, external battery pack at
home.
