Look no further than the Milwaukee 48-59-2401 charger to keep your 12 volt M12 Milwaukee batteries in peak condition. This will handle your 12 volt batteries, charging the more compact models in as little as 30 minutes, with the high capacity models only needing up to an hour to become fully charged. Onboard LEDs status indicators let you know whether your batteries are charging, charged, or are in need of maintenance. Other features include mounting hooks so you can keep this hung on a wall. Feet on the base of the charger let you keep this flat on the ground without wearing the unit down. Keep it in room temperature, dry areas for maximum performance. If there is any maintenance you need to perform on this, it?s as simple as blowing compressed air into the charger to keep dust out.
