OPERATING INSTRUCTIONS Select-A-Charge Battery Chargers models: SCO, SCOXU For Industrial Use: Designed for gel, wet cell, AGM, and Lithium Ion batteries (Lithium ion applications must be factory programmed) Quick Charge Corp. 800 658-2841 e-mail quickcharge@icnet.net www.quickcharge.com Made in the U.S.
If your charger is programmed for Lithium Ion batteries the display will read “FC” Final Charge instead of 80% To discontinue charging, unplug AC power. EQUALIZATION: When using multiple batteries in a series string, cells become uneven during charge and discharge cycles. At least once a month perform two charge cycles back to back, this will give a chance for cells that are lagging behind to catch up, and is important to overall battery performance.
SAFETY INFORMATION AC WIRING: Before making AC connections, refer to the requirements on the charger ID label. If your charger is not equipped with an AC plug, for example, a 230 volt charger, have a qualified electrician install one. To reduce the risk of fire, use this charger only on branch circuits that are protected by a circuit breaker or fuse, and that are adequate to carry the power drawn by the charger.
OTHER SAFETY INFORMATION Do not use charger if it shows signs of physical stress, or if DC output leads or connector feel hot when used. Do not disconnect the DC output clamps, or connector from the batteries when the charger is on. The resulting arcing could cause the batteries to explode. Failure to unplug AC power before moving or driving equipment will result in damage to cords, plugs and receptacles.
Provide adequate ventilation when charging batteries. Chargers can ignite flammable materials and vapors. Do not use near fuels, grain, dust, solvents, or other flammables. Do not charge batteries in excessively hot temperatures; wait till the cool of the evening. PRE CHARGE INFORMATION: Mount the charger in the desired location. Allow space for the charger to dissipate heat, it will get hot while in use. Do not seal the charger in an air tight compartment. Do not cover the charger with any material.
wires are cut or have damaged insulation. Using this charger with any of these symptoms could result in a fire, property damage, or personal injury. Have a qualified service person make the necessary repairs. Repairs should not be made by people who are not qualified. Illustration of series and parallel battery connections: Parallel When batteries are connected in Parallel the battery amp hour capacity is additive and the voltage remains the same.
F5 is for Lithium ion batteries and must be pre-programmed at the factory. The adjustments are: d0 standard gassing/absorption cycle. Applicable to most applications d1 shortened gassing/absorption cycle. For frequent shallow discharging, or frequent recharging of batteries with very little discharge. Suitable for opportunity charging. d2 lengthened gassing/absorption cycle. For batteries requiring long gassing/absorption cycles.
make a change. A reprogramming video is available at quickcharge.com on the Select-A-Charge pages. TROUBLESHOOTING Symptom When plugged into AC power the LED flashes red/green, and a 0 on display. Cause Corrective Action Connected reverse to battery, or not connected to battery. Correct polarity, or connect to battery. Break in DC cord, or connector. Have a qualified person make repair. Battery too dead to charge. Replace. When plugged into AC power the display does not come on. No AC power.
When powered up the LED is solid red with a yellow flash, and displaying 02. The battery is very low, and the charger is in a slow charge phase until the voltage rises to a safe level before full turn on. . Leave connected, it may take hours, but if the voltage rises even a little bit, it should recover, and turn the charger full on. (Do not allow your batteries to deep discharge, it is the number one cause of premature battery failure.
The cycle ends with Er showing, and a green/yellow flashing LED. An incomplete cycle. The batteries did not reach minimum voltage requirements, and the charger bulk timed out. The batteries are too big for the charger. The batteries have defective cells, and cannot make minimum voltage. NOTE: An occasional short cycle is not a problem. Just unplug the charger and plug back in to complete the cycle.
