Battery: 18650 Battery - 3500mAh 3.7V

We use 3,500mAh capacity 3.7V 18650 batteries.  Most other dive lights use generic batteries that have a capacity of 2200 - 2600mAh.  That means our batteries have up to 37% more capacity.  

Capacity : 3500mAh 

Nominal Voltage: 3.7V

Peak Voltage: 4.2V

Protected: No

Protected batteries have a small circuit board integrated into the cell that protects the battery from being overcharged and over discharged.  Our chargers have over charge protection built into them and our lights have over discharge protection in them so we don't need the protection circuits in the batteries themselves.
