The \"Grad.\" mode performs a full charge–discharge–recharge cycle on your battery. This is not just a voltage check—it measures the actual milliamp-hour (mAh) capacity the battery can hold. This is the only way to truly verify if a battery is reaching its rated capacity, or if it has aged and needs to be retired from your high-drain devices.\u003cbr\u003e\u003cbr\u003eQ2: How does the Internal Resistance (IR) test help me?\u003cbr\u003eA: Internal resistance is a key indicator of a battery's health. As batteries age or get damaged, their IR increases. This causes voltage sag under load and excessive heat. The VC8S's IR test lets you quickly check the health of your entire battery collection at a glance, allowing you to pair cells with matched IR for use in custom battery packs.\u003cbr\u003e\u003cbr\u003eQ3: What is \"Storage Mode\" (Store) and why would I use it?\u003cbr\u003eA: Storage mode is designed for lithium-ion batteries that you don't plan to use for a long period. It automatically charges or discharges your battery to its optimal long-term storage voltage (typically around 3.6V–3.7V). Storing Li-ion batteries fully charged or completely empty can permanently degrade their lifespan. This mode prevents that.\u003cbr\u003e\u003cbr\u003eQ4: How do I achieve the maximum 3A charging speed?\u003cbr\u003eA: To achieve 3A charging, you need two things:\u003cbr\u003e\u003cbr\u003eA compatible PD wall adapter capable of delivering at least 15V\/3A (45W) or 9V\/3A (27W).\u003cbr\u003e\u003cbr\u003eYou must use the charger's grouped slots: CH1–CH4 and CH5–CH8.\u003cbr\u003e\u003cbr\u003e3A: 2 bays simultaneously (1 bay from the left group, 1 from the right group).\u003cbr\u003e\u003cbr\u003e2A: 4 bays simultaneously (2 from the left, 2 from the right).\u003cbr\u003e\u003cbr\u003e1A: All 8 bays simultaneously.\u003cbr\u003e\u003cbr\u003eQ5: Can I charge Ni-MH batteries at a faster current?\u003cbr\u003eA: No. The VC8S automatically fixes the charging current for 1.2V Ni-MH batteries at 0.5A × 8 slots. This is an optimal, safe current specifically designed to minimize heat buildup and maximize the lifespan of your AA and AAA Ni-MH batteries.\u003cbr\u003e\u003cbr\u003eQ6: What does the \"0V Activation\" feature do?\u003cbr\u003eA: If your Li-ion battery has been over-discharged to the point where a standard charger won't even recognize it, the VC8S's \"0V Activation\" technology attempts to apply a very low, controlled micro-current to safely revive the cell. While not a guarantee for every battery, it significantly increases the chances of salvaging deeply discharged batteries that would otherwise be discarded.\u003cbr\u003e\u003cbr\u003eQ7: What is the difference between the VC8 and the VC8S?\u003cbr\u003eA: The VC8S is the upgraded successor to the VC8. Its primary upgrades include a USB-C input with support for PD 3.0 fast charging (allowing for higher wattage inputs and faster charging speeds), an upgraded \"0V\" activation circuit for better recovery rates, and an upgraded chip for more precise Ni-MH charging detection.","brand":"XTAR","offers":[{"title":"Default
