OVERHEATING PROTECTION
Gystech 750 charger is protected by a thermal sensor. During the charging process, if the charger
becomes too hot or due to extreme ambient temperature, the power output is automatically
reduced to protect itself from damage. The charger continues to work trickle charge. Charger
increases power automatically when the ambient temperature drops.
