seven days in oat stage to refresh the battery banks.
Understanding The Battery Temperature Functions
The Battery Temperature Sensor is included with the charger to protect
your battery and provide better charging voltage accuracy.
When the battery temperature sensor is used, it is highly recommended
to be installed on the main battery bank at the negative terminal -
Bank one. The sensor senses the battery temperature and overrides
the manual temperature settings and makes small adjustments to the
charging voltage.
Battery Temperature Battery Charging Voltage Adjustment from 25 °C normal setting

< 25 °C + 0.027 V /°C + 0.021 V /°C

> 25 °C - 0.027 V /°C - 0.021 V /°C
When the battery sensor is not in use, you can also manually set the
battery temperature. There are three manual battery temperature
settings on the unit (‘Lo’, ‘nor’ and ‘hi’). See overleaf for voltage
adjustments for temperature compensation.
