I switched a while back to a Cyberpower PR3000LCDRTXL2U UPS with an external battery chassis. We've lost power twice since I installed it, and both times, the UPS has killed power to everything while still indicating 80% capacity before NUT has even initiated shutdown on anything. Here's what upsc reports on it right now: battery.charge: 100 battery.charge.low: 35 battery.charge.warning: 20 battery.mfr.date: CyberPower Systems battery.runtime: 2220 battery.runtime.low: 592 battery.type: PbAcid battery.voltage: 53.8 battery.voltage.nominal: 48 device.mfr: CyberPower Systems device.model: PR3000LCDRTXL2U device.serial: PTEHU2000098 device.type: ups driver.name: usbhid-ups driver.parameter.pollfreq: 30 driver.parameter.pollinterval: 2 driver.parameter.port: /dev/ttyUSB0 driver.parameter.productid: 0601 driver.parameter.synchronous: no driver.parameter.vendorid: 0764 driver.version: 2.7.4 driver.version.data: CyberPower HID 0.4 driver.version.internal: 0.41 input.transfer.high: 131 input.transfer.low: 102 input.voltage: 117.0 input.voltage.nominal: 120 output.voltage: 117.0 ups.beeper.status: enabled ups.delay.shutdown: 20 ups.delay.start: 30 ups.load: 39 ups.mfr: CyberPower Systems ups.model: PR3000LCDRTXL2U ups.productid: 0601 ups.realpower.nominal: 3000 ups.serial: PTEHU2000098 ups.status: OL ups.timer.shutdown: -60 ups.timer.start: -60 ups.vendorid: 0764 I don't think I ever got all the way through NUT configuration on it. What am I most likely doing wrong, or what might I have missed, or what setting am I misunderstanding, that the UPS itself is shutting off the power so absurdly early? -- Phil Stracchino Babylon Communications phils at caerllewys.net phil at co.ordinate.org Landline: +1.603.293.8485 Mobile: +1.603.998.6958

If it would help you there is a shell script at http://rogerprice.org/NUT/nut-report which will prepare a configuration report. (It removes passwords.) Meanwhile, how old is your battery? Very old batteries can produce exactly the effect you describe: crashing rapidly while still indicating high charge. Roger

One observation: "WARNING: I am unable to call script nut-journal to read the NUT activity records in the systemd journal. Either the nut-journal script is not available or you do not have access to the journal for system commands such as those of NUT. Ask your system administrator to add your account to the systemd-journal group. When this is done, log out and then log in and try again." .... OR, you're not running systemd. (Out, out, vile daemon. You shall not pass.)> Meanwhile, how old is your battery?
