The APC SRT systems have a predictive battery alert based on the internal battery RBC installation date. The Message is “Internal RBC Near End of Life” on the screen for this state.

There are two easy ways to change the internal RBC installation date.

Note: Prior to doing these trouble shooting steps if using network management please insure the date and time is set correctly on the SNMP card. Attempting to set the installation date to the future vs the internal clock can cause errors.

First Method:

Step 1: Remove non critical loads if possible, since your system will not be protected for about a minute for this method.

Step 2: Disconnect the battery tray disconnect and wait for the alert screen saying battery disconnected.

Step 3: Then reconnect the battery and when the prompt asks if a new battery is installed select yes. This should clear the issue by setting the internal battery replacement date.

Second Method:

Step 1: This requires the menu system to be changed to advanced mode by going into the configure menu. Depending on the model this will be under the UPS section of the configuration menu or the Display section.

Step 2: Once this is done return to the Configuration section and select the Battery section.

Step 3: The Internal and All RBC Battery installations should now be able to be selected and change both to the correct Installation Date. This should clear the issue but if not reattempt method one again.

If the Installation Date is Stuck or Frozen to an old date after following these steps twice then if could be a State error. State errors can be cleared by following the State Reset – Brain Dead Instructions.
