Battery Heating and Cooling

Battery Heaters

The provided battery heater is located beneath the plate on which the batteries rest. It is designed to prevent the
loss of battery reserve capacity that occurs when batteries are exposed to cold temperatures. The heater is
connected to a thermostat that is set to operate the heater pad when it senses battery temperatures below 32°F
±5°F (0°C ±3°C) and shut them off when it senses above 50°C ±5°F (10°C ±3°C).

Battery Cooling

Battery cooling is provided by the heat exchanger door. The heat exchanger pushes air through vents in the door of
the field cabinet and exhausts the air through vents on the left side of the battery compartment. Outside air, drawn
past the batteries by the heat exchanger, reduces the heating of the batteries that otherwise occurs as a result of
solar heating of the battery compartment sides, by the equipment heat in the field cabinet, and self-heating due to
charging.
This resulting reduction in battery temperature extends the life of batteries.
