Features 1、AUTO VOLTAGE DETECTION: The charger provides automatic battery voltage detection. Therefore, the same device can operate at 12V or 24V without manual selection, eliminating human error. 2、MAIN USE: The charger is designed to permanently connect the generator set starter battery. When the battery voltage is below the floating charge level, the charger provides a constant current that is almost equal to the rated output current, allowing for rapid recovery of lost charges. 3、AUTO MODE CHANGE: When the battery voltage reaches a floating level, the charger switches to constant voltage charging mode and keeps the battery fully charged, providing the longest battery life without overcharging or deflation. 4、OVERLOAD SHORT CIRCUIT PROTECTION: Built in overload and short circuit protection enable the device to only provide rated current when the engine is started or short circuited. No need to disconnect during the startup process. 5、HIGH TEMPERATURE PROTECTION: Built in high temperature protection can reduce output current in case of overheating, allowing operation in warm environments.
