Usage Guide 

1. Plug one end of the power cord or car charging adapter. Plug the other end of the cord into an applicable outlet. The LCD display and all battery indicator bars will illuminate as the charger runs a quick self-test. When test is complete, the name of the product will appear on the screen, the bars will dim and the charger will enter into stand-by mode. If no batteries are detected within 1 minute, the charger will automatically enter Eco Mode (the LCD screen will turn off). When a battery is installed while in Eco Mode, simply press any button to activate the LCD screen.

2. The D4 features two charging slots,each of which charges and monitors a battery independently. Rechargeable batteries of differing chemistries and voltages may be charged simultaneously using either 1, 2, 3 or 4 of the charging slots. When inserting a battery, ensure the positive and negative ends correspond with the positive (+) and negative(-) symbols on the charger. Incorrect installation will result in failure to initiate the charging process.

Note: The D4 is capable of charging 3.7v Li-ion rechargeable cells, 1.2v, Ni-MH/Ni-Cd rechargeable batteries and 3.2v LiFePO4 batteries. See above for description of battery sizes.

3.When a battery is first inserted the D4 will run a short test causing the battery indicator bars to illuminate in sequence from the bottom to the top. When the test is complete, the D4 will enter tint charging mode. If any unusual circumstances have been detected, e.g. a backward battery installation, the battery indicator bars will blink rapidly and “Err” will be presented on the screen to urge an immediate removal of the battery.

4. While in charging mode, the battery indicator bars will blink rhythmically to indicate the on-going charging process. The battery’s power status and charging process is indicated by the number of bars that illuminate steadily. The LCD display will also display battery voltage, followed by charging current and elapsed charging time in sequence. Pressing the side “MODE” button will cycle through there charging parameters. To view the charging progress of a different charging slot, press the side “SLOT” button to select a desired slot. When charging is complete, all five battery indicator bars will illuminate steadily and “Chg. Finish ” will appear on the LCD display.

Note: When the D4 is charging three or four batteries, charging current will be set to 375 mA. Alternatively, when charging either one or two batteries, charging current will be set to 750 mA..


1. The D4 is compatible with batteries of varying sizes, therefore when charging certain batteries(such as 26650 and AAA),manual adjustment of the battery’s position within the slot is recommended, as to ensure solid contacts is made between both sides of the battery and the charging slot's metal contact points.

2. The D4 is restricted to charging Li-ion, Ni-MH and Ni-Cd rechargeable batteries only. Never use the i2 for other types of batteries as this could result in battery explosion, cracking or leaking, causing property damage and/or personal injury.

3. The D4 should only be used indoors or inside a motor vehicle. Do not expose it to water, high humidity, low or high ambient temperatures.

4. Do not disassemble or modify the charger.

5. Children under the age of 18 should be supervised by an adult when using the D4.

6. The D4's safe operating temperature is between 0℃--40℃.

7. Do not use or store the charger near open flames, direct sunlight, heating devices or other high-temperature environments.

8. Guarantee period: 3 months
