Lithium Battery Charger - Dual Battery Charger Compatible with 26650, 22650, 18650, 18350, 17500, 16340, 14500, 10440, 1001-0050 and AA/AAA Batteries. Universal Dual Slot Charger for Ni-MH Batteries

Automatic detection and conversion can charge various 3.0/3.2/3.6/3.7V lithium-ion/iron phosphate batteries and automatically stop charging once fully charged. Intelligent charger: can automatically identify different battery types such as lithium, cadmium, nickel-metal hydride, etc., and intelligently select the charging method. The red light illuminates during charging and turns off when fully charged, at which point charging stops automatically. It switches to a conservation mode, allowing for extended insertion. Protection function: the battery is protected against reverse polarity; short circuits prevent charging; maximum current detection; fully automatic shut-off indicator to protect the battery. Smart Charger: It can fully charge the battery and display an indicator light. Simultaneously, it switches to a maintenance charging mode after a full charge. It can be plugged in for extended periods, which is convenient for users and maintains power. The charging current is low, and the typical charging time is 8 to 30 hours. 1. Smart Charger: It can fully charge the battery and display the status with indicator lights. Simultaneously, once fully charged, it switches to a maintenance charging mode, which can be plugged in for extended periods, making it convenient for users to use and maintain power. Ordinary chargers have a low charging current and a typical charging time of 8 to 30 hours. Users must schedule charging well in advance and, at the same time, unplug the power supply in time to stop charging, which is very inconvenient to use. 2. Charger: Multiple detection and protection features allow for precise battery charging, automatic battery shutdown, and extended battery life. Ordinary chargers calculate charging time based on battery capacity and stop charging at the appropriate time. For various reasons, the battery capacity may not be the nominal capacity, and the precise charging time cannot be accurately calculated, resulting in either overcharging or undercharging. This leads to a shortened or damaged battery lifespan, rendering the rechargeable battery difficult to use and causing financial losses for the user. 3. Intelligent Charger: It can automatically identify different types of batteries, such as lithium batteries, nickel-cadmium batteries, nickel-metal hydride batteries, etc., and intelligently select the charging method. During charging, the red (orange) indicator light is on. When the battery is fully charged, it enters a variable-speed flashing mode, and the charging speed is automatically reduced to ensure the battery is fully charged. The red indicator light turns off when fully charged. The green indicator light is the power indicator and is on when the power is on. Suitable for various sizes of rechargeable lithium-ion batteries (flat-top, convex-top) 1. Automatic identification and conversion can charge various 3.0/3.2/3.6/3.7V lithium-ion/lithium iron phosphate rechargeable batteries and automatically stop charging when fully charged. 2. Current and Vmax detection, complete display with automatic shut-off, protects the battery. 3. The red indicator light is on during charging and turns off when fully charged, and charging stops automatically. Switch to maintenance mode, which allows for extended periods of charging. 4. Battery protection function: short circuit prevents charging, while regular batteries are charged.
