The higher the temp, the lower the voltage. At 120 F it would be about 13 volts. At –20F it would need to be about 15 volts. Easier to overcharge when hot. Harder to fully charge when cold. Sucks for electric cars. From: ch...@wbmfg.com Sent: Friday, July 8, 2016 4:12 PM To: af@afmug.com Subject: Re: [AFMUG] Scary thing to see on a UPS It adjusts float voltage according to temp.

64C input temperature, 64C internal temperature or exhaust temperature? Depending where the diode is on the router PCB...

Re: [AFMUG] Scary thing to see on a UPS
Colin, We had the same thing on Wednesday. Luckily I have an alarm set at 100F for our UPS. Alarms went off and I headed that way ASAP. Our batteries usually run about 90F. -- Best regards, Markmailto:m...@mailmt.com Myakka Technologies, Inc. www.MyakkaTech.com Proud Sponsor of the Myakka City Relay For Life http://www.RelayForLife.org/MyakkaCityFL Please Donate at Please Donate at http://www.myakkatech.com/RFL.html -- Friday, July 8, 2016, 4:12:41 PM, you wrote: CS> A very rural POP, not managed by us, had an A/C trip the CS> breaker.

Re: [AFMUG] Scary thing to see on a UPS
Same exact thing happened to us the other day. Except the APC UPS went into error F07 high temp shutdown. Argh!
