Did not know or install software on my computer at the time I bought APC model BX850M RB1000M that tests the unit

[Elaina]

I have just been made aware that I should have installed some software on my computer that would periodically run a test on my APC purchased about five years ago with new Dell desktop and HP laser printer.  How do I know when it is time to replace the battery in the unit?  If the unit hasn't really done more than a couple back up necessities since installed does that mean the battery would last longer.  How do I know and where do I get the software for the testing?  Does the software run on it's own or do I need to run it manually myself occasionally? Where do I get the software?  The model in BX850M\BX1000M and it is APC is about five years old.  Thank you for your help.

The average service life of the (RBC) Replacement Battery Cartridge is 2-5 years based on usage, temperature, and environmental conditions.

The system by default will perform a self test every 14 days based on first start up which doesn’t require any extra software.

You may refer to the full user manual here for download:

A self test can be manually initiated via the front panel, APC Power Chute. You may download and install the legacy end of life PCPE here:

The RBC is designed to sustain 260 full depletions before degrading but this is subject to charging voltage, temperature, and environmental conditions.

Best practice is to complete a battery calibration / Lights Out / Grid Down test with at least a minimum of 30% attached load.

Doing so will allow the system to provide a better estimate of the operational runtime of the RBC.

You will compare the operational runtime seen on your system with the runtime calculator for your model via the APC Runtime Calculator for your model.

So for example if the load is 150 watts and the system turns off immediately or provides 1-2 minutes - Replace RBC

If you see say 10-15 minutes vs the APC Runtime Calculator of 30. Set aside funds and time to schedule a RBC replacement.
