1. This is a 3.7V 18650 rechargeable li-ion battery cell with a claimed capacity of 5000mAh. However, it is to be noted that the very nature of Li-ion cells does not practically allow them to have a true capacity of more than 3000mah in a 18650 form. These are only for hobby applications and are not meant for industrial use. 
3. Important: Please note that this cell is a copy version and is not original, hence the capacity and performance of the cell might vary based on charging and discharging parameters in your application. We do not recommend this for power-critical applications like Electric vehicles or Solar farms. You can check out Original Hongli 18650 cells for such demanding applications.
