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 different 3.0/3.2/3.6/3.7 Vaulithium-ion/iron phosphate batteries and automatically stop charging once fully charged. Intelligent charger: can identify automatically only different battery types such as lithium batteries, cadmium batteries, nickel-metal batteries, etc. and intelligently select the charging method. The red light turns on while charging, the red light turns off The battery indicator light illuminates when fully charged and automatically stops charging. It then switches to a maintenance charging mode, which can be used for extended periods. A protection function is included: the battery is installed in reverse, preventing charging during a short circuit; it features Vmax current detection; and an automatic shut-off indicator to protect the battery. The smart charger can fully charge the battery and display a light. Simultaneously, it switches to a maintenance charging mode after full charging. It can be plugged in for a long period, which is convenient for users and maintains power. The discharge current is low and the general charging time is 8 to 30 hours. 1. Smart charger: it can fully charge the battery and indicate this with lights. At the same time, once fully charged, it will be replaced by a maintenance charger, which can be plugged in for a long period, which is convenient for users. Use and maintain the power supply. Note: The discharge current of ordinary chargers is low, and the general charging time is 8 to 30 hours. The user must schedule the charge 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, can accurately charge the battery, automatically stop the battery, and extend battery life. Ordinary chargers have to calculate the time discharge according to the battery's capacity and stop charging at the corresponding time. For various reasons, the battery's capacity to be replenished is not the nominal capacity, the precise charging time cannot be accurately calculated, and the battery is either overcharged or undercharged. The result is a shortened or damaged battery lifespan. This leads to the phenomenon whereby the rechargeable battery is not easy 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 light is on (orange). When the battery is fully charged, it enters a variable-speed flashing light state, and the charging speed is automatically reduced to ensure... The battery is fully charged, and the red light is 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.). Automatic identification and conversion can charge various rechargeable lithium-ion/lithium iron phosphate batteries (3.0/3.2/3.6/3.7V) and automatically stop. 1. Charges when fully charged. 2. Current, Vmax detection, full display with automatic shut-off, protects the battery. 3. The red indicator light is on during charging, and the red indicator light goes off when fully charged, and charging stops automatically. Switch to the maintenance supplement, which can be connected for a long period. 4. The battery protection function is reversed; short circuits do not charge, and the regular battery is charged.
