Down4Sound DOWN4SOUND D4S-CHG-15A - 12V Lithium Charger

Description Warranty Information 7 Reviews Description The D4S-CHG-15A charger is an advanced battery charger designed specifically for high performance 12V lithium batteries. This charger combines the reliability of a high frequency MOSFET rectified assembly with an advanced microprocessor control board to create a battery charger that can rapidly and safely recharge 12V lithium batteries in several sizes. Voltage Monitoring The battery’s terminal voltage is measured every five minutes by the on-board microprocessors and this information is analyzed in addition to the elapsed time to dynamically control the battery charger for optimum charging performance. Automatic Computer Analysis/Auto Shutdown The microprocessors will analyze the battery when connected. If the battery’s voltage is below 4V the charger may not recognize the battery is connected and will not begin charging. Likewise, if the battery will not come up to the correct voltage in a ten-hour period the microprocessor control board will automatically shut the charger off. UL Approved Battery Cables. Six feet of durable battery cables are provided that are resistant to cuts and abrasion. The copper plated battery clamps are compact and custom designed easy connections. All clamp connections are soldered for maximum current flow. Internal Cooling Fan A cooling fan automatically operates during charging to keep the circuit and other internal components at a constant safe temperature. Important Safety Instructions The D4S-CHG-15A charger generates a low DC voltage and high DC current to the battery being charged. Operating the charger incorrectly or misusing it may damage the charger or create hazardous conditions for the user. WARNING: EXPLOSION HAZARD • The D4S-CHG-15A charger is designed to charge 12V lithium batteries. Do not attempt to use with batteries with voltages not matching the chargers specified voltage. • Do not use this product where there are flammable fumes or gases. • Do not use this product in an enclosure containing lead-acid batteries. These batteries vent explosive hydrogen gas, which can be ignited by sparks from electrical connections. • Never attempt to charge a frozen battery. • Do not connect DC clamps to the carburetor, fuel lines, or sheet metal body parts. WARNING: SHOCK HAZARD. KEEP AWAY FROM CHILDREN. • Do not expose charger to water or rain or temperatures over 104 °F (40 °C). • Do not open the charger. There are no user serviceable parts inside the unit. For service see the Returns policy in the back of this guide. WARNING: HEATED SURFACE - Ensure at least 2” (5 cm) air space is maintained on all sides of the charger. • An extension cord should not be used unless absolutely necessary. Use of an undersized extension cord will adversely affect the output of the product and could prove to be dangerous. If an extension cord must be used, make sure that pins on the plug of the extension cord are the same number, size and shape as those of the plug on the charger. We recommend a minimum of a 16AWG cord for lengths up to 50’ and a minimum of a 14AWG cord for lengths up to 100’. We do not recommend cords over 100’. Do not use this product with an ungrounded extension cord. • Be sure AC and DC cords are not pinched or otherwise damaged by hoods, doors, or other moving engine components. • Observe battery polarity. *IMPORTANT* If this charger is to be used with a portable generator, it should be equipped with automatic voltage regulation to ensure consistent output of the product. - Specifications Physical Specifications Dimensions (W x H x D) : 8.5” x 2.625” x 3.5” Weight: 3.3 lbs AC Input Connections: 5.0’ AWG 16 DC Output Connections: 4.0’AWG 10 *IMPORTANT*: SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE. 12V LITHIUM BATTERY CHARGER AC Input Specifications AC Input Voltage : 100-120 VAC, 47-63 Hz AC Input Current: 8A RMS fuse protected 15A Protection Battery Reverse: YES Short Circuit: YES Overload: YES Speed controlled cooling fan by charge stage - Back Power Switch and Front LED Indicators 1) Power LED Indicator: Illuminates red when power cord is plugged in and power switch on back of unit is turned on. 2) Charging LED Indicator: Illuminates green when powered on and red when charging. When charging is complete the charging LED Indicator will illuminate green. If the Charging LED Indicator remains red after a 1 hour period, switch the charger OFF and remove the battery connections. Insure the battery polarity is correct, and if so, replace the battery. 3) Power Switch: (on back) Power is ON when switched to “I” and OFF when switched to “O”. 4) Fuse holder: Contains a 25A output fuse in case of overload. *The LED Status Indicator will illuminate RED/RED indicating the battery is charging. The LED indicators will illuminate RED/GREEN indicating the battery is fully charged. - Operation The D4S-CHG-15A charger has been designed to provide fully automatic recharging of most 12V batteries. If possible, disconnect all loads from the battery by removing battery cables, opening a disconnect switch, or switching loads off. To charge your 12V battery: 1) With the charger’s power switch in the OFF position plug the charger into a grounded wall receptacle. 2) Connect the red positive (+) clip of the charger cables to the positive (+) terminal of the vehicle battery. 3) Connect the black negative (–) clip of the charger cables to a solid chassis ground. If this is not possible, connect it to the negative (–) battery terminal. 4) Flip the power switch on the back panel to ON. The Power LED will illuminate red and the Charging LED Indicator on the front panel will illuminate red as well, beginning the charging sequence. *Note that the charger will automatically restart the charging sequence if the charge current rises above a factory preset threshold. When complete, the Charging LED Indicator will turn green, flip the power switch to OFF. 10) Remove the black negative (–) clip and the red positive (+) clip from the vehicle’s battery terminals. - Troubleshooting WARNING: Electric shock hazard Do not disassemble any of the HF chargers. The chargers do not contain any internal user-serviceable parts and attempting to service the unit yourself could result in electrical shock or burn. • Power LED does not come on when the power switch is flipped to ON: Check fuse. Check cord and input power. • Charge LED will not illuminate: The battery is not connected. The battery is below 4.0V. • Charging LED remains orange and never turns green: This happens when the battery cannot be completely charged in a 10-hour period at the selected charge rate. Ensure the battery polarity is correct. If the error persists, replace the battery.

Will recommend this 5 Simple to use and great performance Posted by Ryan Jenning on Dec 04, 2021 Prior to this purchase I had never used a battery charger before so I was a little intimidated but I knew it was necessary to bring my new XS d4700 to a charged state before incorporating it into my system. Talk about ease of use! Attach it to the battery, plug it in, turn it on, walk away. 24 hours later I had my new XS power battery ready to install and have even found uses for this charger outside of that first use. Definitely worth the investment. 5 Very satisfied Posted by Brian Williams on Nov 15, 2021 I’m very pleased with my product 5 Great charger Posted by Chuck daddy on Aug 24, 2021 XS power always delivers. Great quality. 5 D4S 12v Lithium charger Posted by James Williams on Apr 09, 2021 On March 8, 2021 I purchased i realized this product would be required in order to charge the Lithium backup battery I also purchased 3 days prior. Today, April 9, 2021 I finally gotten my car audio installation done. Honestly, I did not charge the battery. My installer did so. I cannot review how it charged all I can say is my LTO is charged and I can assume the charging was without a hitch. From what I understand I shouldn't have to charge it again as long as it doesn't deplete its charge down to 10volts. It appears to be well made and does what it ought to do. 5 Awesome lithium charger Posted by Jose Londono on Mar 02, 2021 The best 15 Amp 12 Volt lithium charger for the price, would recommend!!!!! 5 Awesome charger Posted by Alexander Nielsen on Aug 12, 2020 The charger works great ! It took My lithium battery from 12.6volts to 14.4 volts in less than an hour it also shuts off when battery is fully charged ! This was a Great buy! View All Close
