Schauer 24 Volt, 5 Amp Intelligent Electronic Charger with ring terminal DC Leads. This Fully Automatic charger is for any type lead acid battery, including conventional flooded cell, maintenance free, deep cycle, gelled-electrolyte, or AGM valve regulated batteries. 3-Stage Charge Control provides Modified Constant Current Charge to a constant finishing voltage of 28.8V, then to a float standby voltage of 27.36V to maintain battery in fully charged condition. Charger may be left connected to battery indefinitely, without danger of overcharging. Features: Current limiting Short Circuit and Reverse-Polarity protection (user-replaceable fuse) Capable of full current at 25.2V continuous - 100% duty cycle Mountable, Aluminum case with LED status light Specifications: Finish Voltage: 28.8V (2.4 volts per cell) Float Voltage: 27.36V (2.28 volts per cell) AC Input: 115VAC 50/60Hz 3A DC Output: 24 VDC, 5A AC Cord: 72", with grounded North America 115VAC plug DC Lead: 45", with 3/8" Ring Terminals (12" DC output lead, with replaceable 33" Ring Terminal adapter) Unit Length: 6.5" Unit Width: 3.5" Unit Height: 1.8" Unit Weight: 1.8 lbs. Operation: Not intended for use as a DC power supply Operate in an environment with proper ventilation Do not operate in a damp or wet environment LED Status Indicator Light in normal charge cycle: Green LED - AC Power connected, and charger NOT connected to battery. Red LED - AC Power connected, charger connected to battery, charger in Bulk/Absorption charge mode. Flashing Red LED - Finishing Absorption charge mode. Green LED - Battery charged, charger in Maintenance/Float mode. Flashing Red LED Light indicates battery problems when connected: 1. Charger is connected to a battery with an AH capacity too high to properly charge. (You will need a charger with higher amperage output, see note below.) OR, 2. Charger is connected to a battery with a dead or shorted cell. (Have your batteries tested)
