Lightweight, On-Board, Power Tender: Models: 12V6A, 24V3A The Tender Light Weight On- Board 12 Volt, 6 Amp 24 Volt, 3 Amp GENERAL DESCRIPTION: The lightweight, on-board, power tender, battery charger is a high frequency switching power converter that has a true DC output at a maximum power level of approximately 70 watts. The most common output voltage and current configurations are defined as models in the title block. Check with the factory for other output voltage and current configurations that may be available. Also, a variety of software configurations are available: Standard; Sealed, VRLA, GRT, AGM (Hawker/Optima); and GEL. OUTPUT CABLE CONNECTIONS: The battery charger is equipped with an SPT-2 type output cable with two output leads. The positive polarity output lead has a 3/8" diameter ring terminal with a red molded polymer insulation cylinder. The negative polarity output lead has a 5/16" diameter ring terminal with a black molded polymer insulation cylinder. The standard unit does not have a quick disconnect output cable harness. Quick disconnect output cable harnesses may be available on a special order basis. The price for units with this modification will be higher than those units shown on the standard price list. The price will depend on the volume purchased. STATUS INDICATOR LIGHTS: The following describes the operation of the status indicator lights: RED - When the red light is on, the battery charger is in the process of fully charging the battery. In order to properly charge large capacity batteries, the charger may remain in this mode for several hours or even days. GREEN FLASHING (Hawker/Optima [Sealed, GRT, AGM] Models only) - When the green light is flashing, and the red light is on, the battery is greater than 80% charged and may be removed from the charger and used if necessary. Leave the Deltran Corporation, 801 U.S. Hwy 92 East, DeLand, FL 32724 Page 1 of 10
battery on charge until the green light is solid whenever possible. This will occur approximately 8 hours after the green light begins flashing. GREEN - When the green light is lit, the battery charger is in the storage mode of charge. In this mode the charger will maintain the battery at full charge. If the battery becomes partially discharged due to an external current draw or excessive internal battery losses, the charger will automatically switch itself back to the charge mode of operation. ALTERNATING RED AND GREEN - When the lights switch back and forth, the battery charger is connected to the battery with the polarity reversed. SPECIAL TROUBLESHOOTING INFORMATION: 1) NEITHER OF THE CHARGER STATUS INDICATOR LIGHTS TURN ON: a) Disconnect the charger AC power plug from the AC outlet and recheck that the battery charger alligator clips or ring terminals are connected to the correct polarity battery terminals and that they are making a clean, tight connection. b) Check to make sure that the AC outlet is supplying power by plugging in another appliance like a lamp, or check the outlet voltage with a voltmeter. 2) THE STORAGE/FLOAT MAINTENANCE STATUS INDICATOR LIGHT (GREEN LIGHT) GOES ON IMMEDIATELY WHEN CHARGING A BATTERY KWN TO BE DISCHARGED: a) The battery may be defective. Take the battery to the dealer to be tested. b) The electrical connections between the charger and the battery may not be completely secured. 3) AFTER THE STORAGE/FLOAT MAINTENANCE STATUS INDICATOR LIGHT (GREEN LIGHT) HAS BEEN ON, AND THE AC POWER IS REMOVED FROM THE CHARGER AND THEN IMMEDIATELY RECONNECTED, IT SEEMS TO TAKE TOO MUCH TIME FOR THE GREEN LIGHT TO COME ON AGAIN. a) This is RMAL OPERATION for the LWOB Power Tender. b) Whenever AC power is removed from the charger, including momentary AC power outages, the charge cycle resets. Therefore, depending on the software version, several hours may elapse (8 hours on the Sealed, VRLA, GRT, AGM, Hawker, Optima) before the green light stops flashing. 4) AFTER THE STORAGE/FLOAT MAINTENANCE STATUS INDICATOR LIGHT (GREEN LIGHT) HAS BEEN ON, THE RED LIGHT COMES ON. a) This is RMAL OPERATION for the LWOB Power Tender. b) There has been a momentary AC power outage that reset the charge cycle. c) There is some other load or appliance drawing power from the battery. When the battery voltage drops below 12.0V to V (on 12 volt models), the charge cycle resets. Deltran Corporation, 801 U.S. Hwy 92 East, DeLand, FL 32724 Page 2 of 10
