18650 Battery Samsung 25R – 2500mAh Li-ion 3.7v Rechargeable Battery (Genuine)
High Current 18650 Battery Samsung 25R – 20Ah Discharge Rate – FLAT TOP
+ FREE CARRY CASE
Samsung 18650 Battery is available in THREE following models/sizes:
Flat Top (65mm~ Long) | Button Top (67mm~ Long) | PROTECTED Button Top (70mm~ Long)
18650 Variations – Flat Top vs Button Top vs Protected version
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 Battery Discharge Rate, as some devices (e.g., Power Tools) require High Discharge or High Drain batteries (like this 25R cell) 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.
