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

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

    Very professional. The internal resistance suggests that the cells are reasonably fresh as advertised. Could not be happier with this purchase. Thanks! Jacob
