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.

Smart 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 then switches to maintenance mode, allowing for extended insertion.

Protection function: the battery is protected against reverse polarity; short circuits prevent charging; Vmax current detection; fully automatic stop indicator to protect the battery.

Smart charger: it can fully charge the battery and display the indicator light. Simultaneously, it switches to maintenance mode after full charging.

It can be plugged in for extended periods, which is convenient for users and maintains power. The charging current is low, and the general charging time is 8 to 30 hours. 1. Smart Charger: It can fully charge the battery and indicate the charging status with indicator lights. Simultaneously, once fully charged, it will switch to a maintenance charge, which can be plugged in for extended periods, making it convenient for users to maintain power. Ordinary chargers have a low charging current and a general 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 must calculate the charging time based on the battery's capacity and stop charging at the appropriate time. For various reasons, the battery's capacity may not match its nominal capacity, and the precise charging time cannot be accurately calculated, resulting in either overcharging or undercharging the battery. This leads to a shortened or damaged battery lifespan. This can result in the rechargeable battery becoming difficult to use and causing financial losses for the user. 3. Intelligent Charger: It can automatically identify different battery types, such as lithium, nickel-cadmium, and nickel-metal hydride batteries, and intelligently select the charging method. During charging, the red indicator light is on (orange). When the battery is fully charged, the light enters a variable-speed flashing mode, and the charging speed is automatically reduced to ensure the battery is fully charged. The red indicator light then turns off when fully charged. The green light is the power indicator and is illuminated 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 rechargeable lithium-ion/lithium iron phosphate batteries and automatically stop charging when fully charged.

2. Current, Vmax detection, full display with automatic shut-off, protects the battery.

3. The red light is on during charging and turns off when fully charged, and charging stops automatically. Switch to maintenance mode, which can be left connected for extended periods.

4. Battery protection function: short circuit prevents charging, and a standard battery will be charged.
