How you find out your battery was manufactured in 2012? I did buy an after market battery. How would I know if is the UPS? Maybe I shouldn't spend any money on the current one and I should just buy a new one.

I wonder if mine was supposed to have a smart chip and CyberPower decided not to. The original battery said: battery.mfr.date: CPS>> How would I know if is the UPS? > > That fluctuating runtime sounds suspicious - although the load is also > fluctuating between 32 and 28 in your examples.

I couldn't find an easy way to graph the results. I installed nut-monitor. The nut website says "NUT-Monitor is part of NUT since NUT v2.4.1. It will further evolve toward the NUT Control Center." but nut-monitor hasn't been updated since 2010. Do you know what happened to the "NUT Control Center"? It has an interesting name.

Maybe the UPS is not updating the values that NUT reads very often?
