The XTAR logo, a trademark of Hong Kong XTAR Co., Ltd., contains a spheroidal figure and character that together represent the modest spirit of our company, XTAR being tolerant to diversity and our aspirations towards continuing development and innovation. HONG KONG XTAR CO., LTD CHARGER INSTRUCTION MANUAL E Introduction: ® The XTAR VP2 is a professional lithium-ion battery charger with three charge current options and three voltage options, plus a USB power output feature, which also could do the real-time display for battery voltage (=1.0V)and battery power. It can charge two 10440/ 16340/ 14500/ 14650/ 17670/ 18350/ 18500/ 18650/ 18700/ 22650/ 25500/ 26650 3.0V/3.2V,3.6V/3.7V,3.8V rechargeable Li-ion batteries simultaneously but independently. With a three-stage charge algorithm, activation of batteries, and real- time detection of battery state, the VP2 charges batteries intelligently and safely. The VP2 uses pulse-width modulation (PWM) technology to control a high efficiency DC - DC circuit, which can greatly reduce energy losses while resulting in a more reliable, safe, and efficient charger. In addition, the VP2 provides reverse-polarity and short-circuit protection. Three charge current options (0.25 A, 0.5 A, and 1.0 A) allow you to choose a suitable charge current to balance charge time with battery lifespan. The VP2 uses a soft-start function, to avoid damage from large charging currents . The three voltage options (3.2V, 3.6V, and 3.8V) allow you to choose different charge algorithms based on your battery types. During charging, you can also check out the voltage you selected. In addition, with the USB power output feature, the VP2 can use your Li-ion batteries to charge and supply power for your mobile devices, up to a maximum current of 1.0A. In this mode, the VP2 has automatically stop supplying and power indication function.

When the battery voltage over 1.5 V, the charger can display the real-time battery voltage, and when the battery voltage is between 1.5 V and 2.0 V, the battery icon will flash, indicating that the battery is in activating. Because of the difference of the battery quality, discharged times, capacity and discharge degree, its activation time will be different, and some of the over discharged battery cannot be repaired. The charger has three optional current to choose, users can choose different charging current based on the battery's performance in order to achieve slow charging, medium speed charging or the quick charging. For low capacity's battery, our suggestion is to choose 0.25A gear to charge, it can make the battery saturate and benefits to its service life. This product only apply to 3.6 V or 3.7 V rechargeable lithium ion battery. Please do not charge the batteries which are unsuitable, otherwise may lead dangers. Please keep this product away from water and dust, and use it in dry environment. Disassembly and modification are strictly prohibited. Charging Batteries = Connect the supplied power adaptor to the VP2. The VP2 performs a self-check, turning on two LEDs (Red status indicator). When the charger is being self-checking, LCD display the full bar to the battery icon and the selected voltage. After about two seconds, the two indicators turn green. Then the charger switches to standby mode, no battery icon will be displayed but the selected voltage and default 0.25A charge current. = Slide the voltage setting switch to choose the suitable voltage for your battery. The LCD will display the corresponding selected voltage. For example, if your battery's nominal voltage is 3.6V/3.7V, then you should choose the 3.6V voltage and LCD display 3.60V in the standby mode. = Choose the charge current that best suits your rechargeable Li-ion batteries: 0.25A: suitable for 10440-18700 Li-ion batteries; 0.50A: suitable for 18700-26650 Li-ion batteries with capacity = 2500 mAh); 1.00A: suitable for Li-ion batteries with capacity = 2000 mAh, 1.0A is the large charge current for fast charging. = Press the Charge current setting button one or more times to change to a different charge current. Current arrangement is 0.25A-0.5A-1.0A-0.25A. = During charging, double-press the current-change button to check the selected voltage setting. The corresponding slot LCD display the selected voltage. Choose the voltage setting suitable for your battery. After about 3 seconds, the LCD reverts to show the charge current, battery real-time voltage and charge status. The VP2 has integrated short-circuit protection to protect the charger if a short circuit occurs in a battery. Note that this short-circuit protection protects the charger; it does not prevent batteries from short-circuiting internally. Keep the VP2 away from water and excessive dust. Do not disassemble the VP2; damage may result. Do not use any damaged VP2. Tips: The USB power output is available only when no external power source is connected. and battery is being insert to CH1 slot. Press and hold the charge current setting to check the selected voltage. Suitable voltage is strongly being recommended. Because of different battery types, capacities, and over-discharge depths, the battery-revive time may vary; heavily over-discharged batteries may not be able to be revived. Don't judge the battery is being charged or not when itis in the process of activation. To lengthen the over-discharged or long time no used battery lifespan, 0.25A charge current and suitable voltage are strongly being recommended. Specifications and features are subject to change.
