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 batteries, cadmium batteries, nickel-metal hydride batteries, etc., and intelligently select the charging method. The red light illuminates during charging and turns off when fully charged, and charging stops automatically. It switches to a conservation compensation mode, allowing for extended use. Protection function: the battery is reverse-connected, preventing charging in case of a short circuit; maximum voltage detection current; automatic shut-off indicator to protect the battery. Intelligent charger: it can fully charge the battery and display a light. Simultaneously, it switches to a maintenance charging mode after 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 lights. Simultaneously, once fully charged, it will switch to a maintenance charge, which can be connected for an extended period, making it convenient for users to use and maintain the power supply. 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, disconnect 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 must calculate the charging time based on the battery's capacity and stop charging at the corresponding point. For various reasons, the battery's capacity may not be its nominal capacity, and the precise charging time cannot be accurately calculated. The battery may then be either overcharged or undercharged. The result is a shortened or damaged battery life. This leads to the rechargeable battery becoming difficult to use and results in economic 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) 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 light turns off when fully charged. The green light is the power indicator and is on when the power is on. Suitable for different sizes of rechargeable lithium-ion batteries (flat top, convex top, etc.) 1. Automatic identification and conversion can charge various rechargeable lithium-ion/lithium iron phosphate 3.0/3.2/3.6/3.7V batteries and automatically stop charging when fully charged. 2. Current, Vmax detection, full display with automatic stop, protects the battery. 3. The red indicator light is on during charging and turns off when fully charged, and charging stops automatically. This allows for extended use and can be connected for a long period. 4. The battery protection function is reversed; the short circuit does not cause charging, and the regular battery is charged.
