Low Runtime
CyberPower UPS
Severity: ModerateWhat Does This Error Mean?
Low UPS runtime — battery draining faster than expected — is usually caused by too many devices connected or an aging battery. Reduce load to under 80% of the VA rating and check the battery age. Most UPS batteries last 3-5 years.
Affected Models
- CyberPower CP series
- CyberPower BR series
- CyberPower OR series
- CyberPower PR series
Common Causes
- Too many devices connected to battery outlets
- Battery degraded from age — typical lifespan is 3-5 years
- Battery never fully recharged between outages
- High ambient temperature reducing battery capacity
- Battery replaced with wrong Ah rating — too small for the UPS model
