High Ambient Temperature:
The air temperature in the battery string environment is above the configured threshold. Default high threshold: 95.0°F (35°C) Check temperature control and ventilation systems in the room, and check for overheated batteries (usually caused by overcharging). NOTE: Lead-Acid batteries provide optimum output and longevity at 77°F. An uncorrected high temperature can significantly shorten the life of the battery string.

Low Ambient Temperature:
The air temperature in the battery string environment is below the configured threshold. Default low threshold: 50.0°F (10°C) Check temperature control and ventilation systems in the room. NOTE: Lead-Acid batteries provide optimum output and longevity at 77°F. An uncorrected low temperature can prevent the battery from providing adequate power to the UPS, and will cause the UPS to drop the load prematurely.
