The RT-UPS will try to charge its internal battery whenever an input power supply is
present and charging is necessary. The internal battery is protected against charging
outside of its specified charging temperature range.
If the battery temperature exceeds approximately 65°C, charging will be suspended
until the temperature falls to around 60°C. If the battery temperature falls below
approximately 0°C, charging will be suspended until the temperature reaches
approximately 5
°
C.
If the battery temperature approaches the lower threshold, the fan is temporarily
disabled to avoid unnecessary cooling that might prevent charging by actually holding
the battery at a low temperature.
