The OSRAM BATTERYcharge 904 is a charger and maintainer for vehicles with 6V or 12V electrical systems. It provides a 4A continuous output to maintain batteries, including lithium, lead-acid, and AGM types. Once the charging cycle is complete, the device automatically switches to maintenance mode to prevent overcharging. It is designed primarily for motorcycles and compact vehicles that require regular battery upkeep, keeping them ready to drive after periods of inactivity.

An integrated digital display shows real-time feedback on the battery's condition. The unit includes protection against short-circuits and reverse polarity. You can connect the charger to the battery using the included crocodile clamps or the O-ring terminals for more permanent setups. A microprocessor manages the charging process for both lead-acid and lithium batteries, requiring no manual intervention.
