Why the green light never come on? Please check the capacity of your battery, this charger only suitable for charge 30AH~60AH lead acid battery 2.Why the charger get very hot while charging It is normal for the charger to heat up during use. If overheating occurs, please check whether the following conditions exist: whether it is charged in the sun, the battery does not match the charger, the charging time is too long, the current and voltage are too large, and the battery electrolyte is missing
