Ansmann Li-Ion battery 18650

Easy Charging
The battery can be charged using a standard Micro-USB charging cable. Power sources can include a PC, a power bank, or a USB power adapter (5V). Alternatively, a lithium charger can also be used.

Perfect Protection Thanks to Safety Board
The integrated Safety Board protects the cell from overcharging, overload, short circuits, or deep discharge. This ensures that the battery is perfectly safeguarded against misuse, guaranteeing a long lifespan.

High Energy Density
Compared to conventional NiMH batteries, Li-Ion technology has nearly double the energy density at the same size.

Lightweight, Low Self-Discharge, and High Cycle Stability
The ANSMANN 18650 Li-Ion battery is extremely durable and can be recharged up to 2000 times even under harsh conditions. Due to its very low self-discharge, the battery retains its energy for a long time even when not in use. Additionally, the weight of the Li-Ion cell is significantly lower compared to traditional battery technologies (e.g., NiCD/NiMH/PB) at the same performance level.

Versatile Applications
The high-quality lithium-ion battery from ANSMANN is ideal for use in modern devices such as LED flashlights, headlamps, laser pointers, etc. The cell has a capacity of 3400 mAh, making it perfect for "power-hungry" devices with high energy demands. Furthermore, the battery can be used over a wide temperature range of -20 °C to +60 °C.

Note:
Due to the integrated protection circuitry, the cell is approximately 3-4 mm longer than unprotected 18650 Li-Ion batteries. Please do not confuse it with a standard Mignon AA battery, as these are smaller than the 18650 cells.
