TYPE-C POWERED, QC3.0 3A FAST CHARGING Applied the most popular Type-C port, compatible with most phone adapters on the market, no more need for another. Support QC3.0 fast charging, max 3A for a single slot when the battery resistance is low enough. TEST BATTERIES' REAL CAPACITY In grading mode (for CH1-CH4), the charger tests batteries' real capacity by "charging-discharging-charging" the batteries, so that users can know whether the battery capacity is overstated or not, and also distinguish good-performance batteries with the bad ones. MAXIMIZE BATTERIES' LIFESPAN The charger can charge or discharge the battery to its rated voltage in storing mode (for CH1-CH4), when the battery is not used for a long time or used for long-distance transportation, so as to maximize the battery lifespan and save energy. *When the battery voltage is at its rated voltage, its self-discharge rate is the slowest and also most stable. DETECT THE BATTERY TYPE Select the Best Charging Strategy After inserting batteries, the charger will automatically identify the battery type, along with battery resistance and input power, to select the most suitable charging method, so that users don't need to select manually. OAV AND -AV METHOD PRECISELY CONTROL the Timing for Cease of Charging Ni-MH/Ni-CD Batteries According to the charging features of Ni-MH/Ni-CD batteries, VC8 applies high-precision MCU and controls perfect timing for the cease of charging with 0AV (0 Delta Voltage) and -AV (Minus Delta Voltage) method, to deliver maximum power while maximizing the batteries' lifespan. FIVE OPTIONAL CURRENTS FOR MANUAL Adjustment Besides the intelligent charging, the charger also has 5 optional currents (3A/2A/1A/0.5A/0.25A) for users to choose from according to different needs. MONITORS AND CHARGES each of 8 Slots Independently Can charge eight batteries simultaneously, save your time and improve the efficiency. VA LCD SCREEN SHOWS Real-time Charging Status High-definition VA LCD screen shows batteries' real-time charging status in charging mode, grading and storing mode. MULTIPLE PROTECTIONS Ensure Safe Charging Built-in high-precision MCU, over-current, over-charge, over-voltage, and short-circuit protection, combined with XTAR's soft-start function, makes the precision of end-of-charge voltage up to ±1%. The charger will automatically stop charging after fully charged batteries, safe and worry-free. SAFE MATERIAL Constructed from flame-retardant and fire-resistant ABS materials to extend the charger's lifespan and ensure safety. TEMPERATURE MONITORING DESIGN Built-in real-time temperature control protection system makes the battery charging process more stable. OV ACTIVATION REVIVES OVER-DISCHARGED BATTERIES XTAR charger can activate some revivable batteries. Insert the battery and the charger will automatically detect and activate the battery. THREE-STAGE CHARGING MAKES BATTERIES HEALTHIER Specially-designed TC-CC-CV charging method safely and efficiently charges your batteries. The charger uses trickle current (TC) to "awake" and protect batteries when the battery voltage is very low. After the voltage becomes normal, the charger starts constant current (CC) charging and the charging speed is guaranteed with a large current. When the battery is almost fully charged, the charger starts constant voltage (CV) charging, to make sure the battery is fully charged and less-damaged. TIPS:1) Please use only compatible batteries to avoid damaging both the battery and the charger.2) It is recommended to use 15V 3A PD adapter for better charging experience.3) Due to the characteristics of Ni-MH batteries, batteries that have been stored for a long time need multiple charge discharge cycles for recovery before testing the capacity. Otherwise, the test results may deviate greatly from theactual capacity.4) Due to the characteristics of Ni-MH batteries, when test the internal resistance, they need to be charged anddischarged for recovery, and then test in a fully charged state. Otherwise, the test results will be seriouslyinconsistent.5) When testing the IR of AAA batteries, it is recommended to conduct multiple tests or firmly press the negativeterminal to ensure that the test results closely approximate the actual values.
