[WISPA] Overheating UPS?
One of my UPS's at a house/tower was chirping, I sent a technician to pull the unit in for testing. It was so hot that they had to wrap it in towels to move it, it wasn't chirping when he got there. It has a minimum load of about 3-4 amps for a couple Mikrotik and Motorola radios on it with a switch and remote reboot unit. The UPS was in an attic of the house and it is averaging about 95 degrees (we don't have humidity here) outside so I figure over 100 in the attic. I'll let it cool down overnight in the office but my guess is the chirping was a high temp warning, any ideas? SmartAPC Model SUA 750 - about a year old. Forbes WISPA Wants You!

It is getting ready to fail.I have had two APCs that got hot and failed soon after.One made for an awful stink in the NOC when it finally went. I thought the building was on fire.

Re: [WISPA] Overheating UPS?
I've had the 2u rackmount APCs eventually get hot and overcharge the battery. They'd be quite warm with little or no load, and the batteries would bulge. This is in 72f datacenter. They last much shorter in 95 degree heat in my opinion. When it happens, we pull them out of service and use a tripplite APS. For small cheap UPSs we get a APC backups or tripplite or whatever is onsale at staples.

Re: [WISPA] Overheating UPS?
Honestly isn't this something the Underwriters Laboratory would be interested in since they certify these units?
