I'm not sure this will get a lot of feedback, but hopefully it'll help someone. Anyway, shout out to CyberPower.
I have a CYBERPOWER BACKUP POWER SUPPLY - CP1500PFCLCD that I purchased in Mar of 2018 (a $220 dollar unit).
Three weeks ago, the UPS completely shut down with a F03 error code and wouldn’t power anything. Turning the unit back on would only last about 10 to 15 minutes before shutting down again.
Calling CyberPower’s tech support revealed the fault code indicated a charging issue. However, it was uncertain whether the issue was the charging system itself or a dead battery unable to be charged.
It was at this point in the discussion that the tech support rep volunteered to send me replacement batteries free of charge as he did not want to see me spend $90 bucks on something that may not solve my problem… If I bought batteries and unit still exhibited the same behavior, I’d be out of 90 bucks and still have a dead unit. Mind you again…. The unit was already out of warranty.
Anyway, I got the batteries about 4 days after that phone call, and thus far two weeks in the unit has been running flawlessly on my backup system. So, yeah, dead battery problem.
BTW, it turns out that as the charging system kept trying to charge a dead battery, that in turn caused an overheat condition, which in turn shut the UPS unit down to prevent further damage. I say that because of how the old batteries were when removed from the unit. That said, it could have just as easily been the charging system itself that was bad, and thus why I suspect the tech sent me batteries instead of having me buy them. To quote him… “I hate to see you buy batteries and the unit still not work”
Anyway, kudos to CyberPower for going above and beyond, instead of simply giving me the "sorry, the unit is out of warranty, nothing we can do" line.
All said, be reminded UPS batteries do need replacing. CyberPower states 3–6-year battery life depending on discharge/recharge cycles.
Peace
