EVE INR18650-35V Rechargeable Battery, 3.6V 3500mAh Li-ion (Flat Top)

The EVE INR18650-35V is a high-capacity rechargeable lithium-ion cell made by EVE Energy, one of the large battery manufacturers. With a rated capacity of 3500mAh it stores noticeably more energy than the common 2000 to 2600mAh cells, so your UV torch runs longer between charges.

In an independent test by akkutests.de the cells measured slightly below the printed figure, just under 3400mAh at low current, with an internal resistance of about 25 mΩ. The positive terminal is flat top and, like every cell of this model, it has no built-in protection circuit. It makes good contact in the Convoy S2 and C8 flashlights.
