What’s the best 18650 battery and what type to choose?

Panasonic 18650 Batteries are available in THREE following models/sizes:

Flat Top (65mm~ Long | Button Top (67mm~ Long) | PROTECTED Button Top (70mm~ Long)

NCR18650B Variations – Flat Top vs Button Top vs Protected version
NCR18650B Variations – Flat Top vs Button Top vs Protected version

Three Types of Panasonic NCR 18650 B 3400mAh Li-ion Torch Battery

Please carefully measure your device’s battery compartment and choose the correct version. (e.g., Most Doorbells and Solar Cameras ONLY work with Button Top ( 67mm~ version). Another factor that needs to be considered is an 18650 Lithium Battery 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.
