Even aftermarket batteries have those?
The battery I bought was cheap.

I wonder if mine was supposed to have a smart chip and CyberPower 
decided not to.
The original battery said:
battery.mfr.date: CPS

It is my 8 core desktop computer and not much goes on.
The runtime fluctuates way more than the load.

I'm going to setup upslog.
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.
