Hi,

I am going to build a system based on rechargable batteries (NiCd). At any
time, I need to know for how many minutes can this system run without
charging. The batteries will under normal condition be charged for 2.5
minutes and discharged for 2.5 minutes. This will go on for weeks, so I
need a reliable way to tell when it's time to change batteries. And, I need
to know before the batteries fails.

-To keep On Topic, This will off course be done by a PIC...

Has anybody got any experience with this kind of problems??

Regards,
Haavard
