Description Automatic Charger Marine M 100: Activates batteries with sulfate content, reactivates deeply discharged batteries, and provides pulse maintenance charging for maximum lifespan. An excellent marine charger that offers complete battery care for small boats with a 12 V battery, used as a starter and service battery. The M100 is a fully automatic 8-stage charger with a charging current of 7 A. It is ideally suited for batteries up to 150 Ah and for maintenance charging of up to 225 Ah. The M100 analyzes whether the battery can receive and hold the charge, eliminates harmful lead sulfate crystals, delivers effective charging, and automatically switches to a safe maintenance charge after the charging process is complete. The practical Recond mode reconditions the battery after a deep discharge, which can occur after a long day at sea. The AGM mode provides optimal charging for AGM batteries, which require a slightly higher charging current.
