How to reset date after battery replacement of apc matrix 3000 ups

To reset Bad Battery light on the Smart cells:

Old smart cells have a removable cover on the back to allow the "socketed chip" to be replaced.

Newer ones have SW1 pads on their circuit board.

Newer Smart Cell or XR Cabinet

1. Unplug the phone cord from the smart cell and wait a minute for the controller to go to sleep

(Bad battery indicator goes dead)

2. Then push the reset Button while plugging the phone cord back in.

3. If it is blinking after plugging back in, disconnect and wait till dead and try again.

4. If the batteries are good you should not get a light at all. Retry the reset at least 2 more times before

blaming the card.

Older Smart Cell

1. Unplug the phone cord from the smart cell and wait a minute for the controller to go to sleep

2. Short pins 17 and 28 (Right Side, Top and Third from the Bottom), while plugging the phone cord back

in.

When it works the red LED will be blinking indicating a bad Battery, it should stop blinking when the phone cord is plugged back in.
Note: Smart Cells are functional when LED is blinking

Agree with Eric... Two thumbs up
