I finally managed to hook a wrench around the top and pull them out. The plastic pull tab broke off when I tried to pull out the batteries. When I got the battery door open, I could see the batteries bulged somewhat and were very hot. 12V 8Ah Replacement for APC Back-UPS ES 500 UPS Batt.Of greater concern was that the unit was almost too hot to touch.
The building where this unit is installed does not have air conditioning, but the high in San Diego that day was 71 F, so the room was well below 80 F (27 C). The temperature was 40 C when the unit reported “battery disconnected.” Is it a coincidence that 40 C is the temperature at which the fan turns on ( KB article)? Perhaps some safety switch was tripped to disconnect the battery? The fuse between the batteries did not trip.Here’s the event log, showing the “battery disconnected” event at 2:39pm:And here’s the temperature graphed from 4:10am to 4:50pm:According to its specs, the DLA1500 is supposed to operate safely in an environment up to 40 C. I disconnected the two batteries from each other and left them outside overnight to cool.Reviewing the PowerChute data log, I see that the temperature is usually around 30 Celcius (86 Fahrenheit), but starting at about 7:30am, it slowly climbed to 41 C (106 F).
It turns out that the default setting for “UPS Internal Temperature Threshold Exceeded” event is 70 C (158 F):Wow! If the unit is almost too hot to touch at 40 C, 70 C seems way too high.I don’t know how accurate these internal temperature sensors are. If it has risen 10 C in one day, consider a shutdown and get on site.I wondered why PowerChute hadn’t warned me about the overheating. Fortunately, it was a convenient time, so I went on site within a couple hours and discovered the overheated unit.Next time: carefully check the Internal UPS Temp column in the Data Log. All I got was the “battery disconnected” warning since the server was still up, I didn’t consider it an emergency. What Should Have HappenedI am definitely concerned that this high-end UPS did not detect a failed battery or an overheating condition earlier.
No advance warning to replace battery.The unit was burning hot, so I powered it down, removed the safety disconnect plug in the back, and took the front off to allow the batteries to cool faster, and I also took out my thermal camera which showed a temperature of between 50 and 70☌ on the batteries a good 40 minutes after power down. I then went to check on it, and it gave me a “battery disconnected” error, that then switched to a “new battery connected” question, and back to battery disconnected over and over, and the battery voltage jumped back and forth between 0 and 24 V. I checked and the battery was at 3%.
My ESXi box will be shut down after 2 minutes over SSH by a script on the Pi. The Synology is monitoring the NUT server on the Pi, and will shut down after 10 minutes. I tried apcupsd which has access to some more specific data from APC units, but it wasn’t compatible with the network ups support in my other devices. As a regular non-business consumer using it at home I don’t have too high hopes for goodwill, but I’m going to contact them tomorrow to voice my concerns.As far as the Pi, I’m using NUT. It’s 5 years old at this point and with it’s original batteries from factory.I have yet to contact them. Not impressed at all.Not sure if the unit is good with new batteries or if it needs replacing.
On the other hand, the few times where there is a power failure on a neighborhood level my fiber connection will go down either way unfortunately. It will either have to shut it down immediately on power down, or not shut it down at all. Remote syslog could also be useful as /var/log would be erased when it’s powered off using this method.The problem with connecting it straight to the Synology is that it then can’t keep the UPS on for the network equipment. Otherwise the micro SD will wear out pretty quickly. This is enough to keep the network going for 2-3 hours.The Pi works well, but I would recommend to put /var/tmp, /var/log and /tmp on ramdisks (tmpfs).
