Issue:
A battery status check indicates a low or dead battery.

Product Line:
Micrologic trip units used on Powerpact P, R, and Masterpact NT and NW
5.0A, 6.0A, 5.0P, 6.0P, 5.0H, 6.0H

Environment:
S33593

Cause:
Battery depassivation

Resolution:
One recommendation is that the battery indicator symbol be ignored and that the battery status be checked by pressing the status check button and observing the four LEDs at the top of the trip unit. If the three/four LEDs light while the button is pressed, the battery is good. If the LEDs do not light, the battery is dead and needs to be replaced.

The battery life is published at 7-10 years.
