Over-temperature Internal charger temperature is measured. Charger
shuts down and restarts as follows:
• Shutdown at 70 °C (158 °F)
• Restart at 65 °C (149 °F)

temperature
protection
Battery temperature, as sensed by the battery
temperature sensor (if installed), results in the
charger no longer charging the individual battery or
bank at a battery temperature of 70 °C (158 °F).
