I have some old UPS devices which I’m going to have the batteries replaced in this week.
The one on the left is the OPTI-UPS Enhanced Series – ES-C 1KVA.
The one on the right is the PowerShield Defender 1600VA.

I had to get new batteries in four of my UPS devices which involved a lot of plugging and unplugging. Since I was down there under my desk I took some time to vacuum and do a better job of my cable labeling.
While I was sorting cables I found one with a frayed end which I decided to keep for spare parts. In makes me nervous just looking at this thing. That’s a mains power lead with bare ends, it’s a death sentence waiting to happen! But that bit of cable with that attachment might very well come in handy some time so I will file it in its relevant drawer.
I was watching Computers running very slow, long boot time, unresponsive in windows. Let’s fix it. and Richard said that if your CMOS battery reads less than 3V then you should replace it.
Today I watched How much current can a 9V battery supply? Let’s test it! over on YouTube.
So today I added a Power section to John’s Linux page.
Particularly some notes on using the ‘upsc’ and ‘upscmd’ commands in Reporting on PowerShield DEFENDER UPS status and Run commands on PowerShield DEFENDER UPS batteries sections.
