Our Smart-UPS VT 10 kVA: ran a scheduled weekly self test, the test failed with 'A weak battery exists', contacted our UPS maintenance company who sent tech to site, he tested and could not fine the weak battery, in fact he said it was all good (waiting on report from tech who did the testing).  we're still getting the alert every 2 minutes though for weak battery and self test failed ??, below are the SNMP traps being generated.  Anyone seen this before?  Tech thinks it may well be system generated alert has been triggered after X amount of time, UPS has been in production for about 2 years 8 months.

snmpTrapEnterprise = PowerNet-M​IB:apc
experimental.1057.1.0 = 10.9.128.2​51
sysUpTime = 354 days 21 hours 36 minutes 55.30 seconds
snmpTrapOID = PowerNet-M​IB:apc.0.3
mtrapargsString = UPS: Self-Test Failed

snmpTrapEnterprise = PowerNet-M​IB:apc
experimental.1057.1.0 = 10.9.128.2​51
sysUpTime = 354 days 21 hours 36 minutes 52.80 seconds
snmpTrapOID = PowerNet-M​IB:apc.0.7​7
mtrapargsInteger = 36
mtrapargsString = UPS: A weak battery exists.

Paul,

When the tech was on site did he run a self-test and if so did it fail? If he did not run a self-test I suggest doing so to see if the error clears. You can run the self-test via the NMC.

My experience with the SURT 10kVA is that if there is one bad battery in any of the four cages (out of a total of 32 batteries!), it will fail the "load" test upon startup.  The "VT" series is advertised to have more "intelligent" charging system - it is possible that it can determine if any of the (many) batteries are about to fail.  Just checking voltages of the battery cages will not indicate a single (or more) bad batteries due to "surface" charge.  There must be some type of "load" test.  Check how the technician did the test and the results.

Thx Bill, ran the self-test via NMC and it failed.  Looks like the default setup is that a notification is generated every 2 minutes until problem is fixed, do you if you can stop the alarm notification ?
