If this LED is on immediately after installing a new battery pack, it
indicates that an initial battery charging and conditioning cycle is in
progress. The initial battery conditioning takes approximately 24
hours, and the LED will turn off after the cycle is complete.
If this LED is on during normal operation (not after installing a new
battery pack), either the battery has exceeded its two year life or a
problem has been detected. Check the battery status before
determining any service operation.
