I just got a Utrafire WF-138 charger, 2 x Ultrafire 16340 rechargeable and a Jetbeam RRT-0 R5.



I have been using the first battery till the flashlight shut down abruptly.

Trying to recharge the battery, the charger displays red, and then a flash every 1 sec. after 5 min it goes green. Now that´s not right. Popping it back in the Jetbeam it shuts down after 40 sec. on high mode.

Charging voltage set to 3.6 v. -Battery is 16340, 880 mAh, 3.6V Li-ion.



Is it the charger or the battery? :thinking:
