Battery was charged to 4.22 Volts with Charger SKU:600-625-001. I tested this battery using Flashlight SKU:0005838-001 (XM-L), with 2.36 Amp draw on high setting. The test was terminated after 14 minutes when the battery was at approximately 35% capacity. My estimate is that it would have provided 20 minutes total light, with a true capacity of 800 mah (millampere-hours). Battery may suitable for low current draw applications. Another battery from Meritline, SKU:188-895-001, under identical conditions showed 1800 mAh capacity, and was more suitable for high current drain flashlights.

These batteries FROM MERITLINE work ++GREAT++ in every flashlight I throw at them. Other Ultrafire 18650 batteries that I have bought (from a famous auction site and elsewhere) are TOTALLY unstable and noticeably dimmer. The Meritline Ultrafire 18650 batteries I received say output is 3000 Mah; other Ultrafire 18650 batteries from other sources say 3500 Mah. Otherwise the Meritline Ultrafire batts look EXACTLY like the other Ultrafire 18650 batteries. Same EXACT packaging But the batteries from other sources are dimmer and some just do NOT work in the higher-end flashlights for sale here, like the $28.99 188-738-001. Others have reported this problem. The high setting cuts out without warning and sometimes the flashlight will go into the strobe setting for no apparent reason. This does NOT happen with the Meritline Ultrafire 18650 batts. They work FLAWLESSLY. I have a feeling that the other Ultrafire 18650 batts (NOT the ones from Meritline) are counterfeit or otherwis

Bought the battery for a 3W LED flashlight also from Meritline. Also bought a charger to complete the kit. Everything is as listed.

This is a truly amazing product - excellent capacity, and recharges very nicely. In an LED flashlight I also bought from Meritline, it works for many hours, so I recommend it highly.

Prob not the battery's fault, but insufficient to power one of the Cree lights (0003575-001) for more than 20 mins. Trying a 5000mAh from another vendor. Should have known that 2000mAh wouldn't last long.
