Olight 18650 Button Top Battery for H2R Headlamp

3000 mAh, 3.6V

The Olight 18650 3000mAh 3.6V Button Top Battery is a specially designed cell built specifically for use with the Olight H2R Headlamp. This specialized battery features a powerful Lithium Ion chemistry, which provides the potent power necessary for the H2R to reach its Turbo output. The Li-Ion chemistry also gives the cell a sizable capacity of 3000 mAh, enough to run the headlamp on its lowest brightness for an astounding 45 days! Unlike other 18650s, this specially designed battery can be recharged while still inside the H2R using the magnetic charging cable included with the headlamp. This convenient charging method is quick and gets rid of the need for a designated charger, saving the user both time and money.
