Three Different Types of Panasonic NCR18650B Li-ion Lithium 3400mAh Batteries


Please carefully measure your device’s battery compartment and make sure to choose the correct version. (e.g., Most Doorbells and Solar Cameras ONLY work with NCR18650B Buton Top 67mm~ version). Another factor that needs to be considered is a 18650 Cell Discharge Rate, as some devices (e.g., Power Tools) require High Discharge or High Drain batteries to be able to supply a high amperage in a shorter time on demand.

Note: Unlike a number of generic products in the market claiming unrealistic high capacities, we ONLY supply GENUINE and fresh batteries. Each cell is tested before dispatch.
