Question: will these batteries work for my flashlight which requires a 1x18650 ultra fire flashlight?
Document: 10-21-2013, Rev. B.Not much to say. It works. Charges fine. It works with 1600LM Cree XM-L T6 headlamp, and another high powered LED flashlight (SSC-P7).I got the blue in color 3600mA Ultra Fire batteries.
I gave this battery charger combo a 4 star rating insted of a 5 star rating because there wasn't any information manual sent with it as to charging times, other than that it seems to work well so far, charged up the batteries in a few hrs and the batteries are working in my Unique Fire LED flash light as expected. ( Have only used the charger once so far) I definitely would purchase this battery, charger combo again because I think it is a great buy for the money!
i bought these to keep at work for spares since I'm always using my flashlight. For those that don't know much about batteries, the higher the mah the longer it will last.
Great product! I needed batteries for my flashlight. I work in a prison so I need the batteries to be charged and this product makes sure I have that.
I bought these to go with Trustfire Cree Xm-l T6 5-modes 3800lm flashlight. The batteries work like a champ and the price was right.
I am in law enforcement, I work overnight, and my Flashlight is my life. I purchased these batteries because I was going through about 9 AAA regular batteries every 2 weeks. These 18650 batteries came with no charge, so I followed the directions and fully charged them. They lasted for about 3 days then began dimming. I fully recharged them and they began dimming only about 2 hours of very intermittent use. I ordered other batteries from EAGLETAC, and will put these in my backpack for emergency back up.
On the first use one of the batteries caught fire and melted. Burnt my hand when I tried to unplug it. Got a second degree burn. If I wasn't home it would have burned down my house!
Out of the 6 batteries 3 are now garbage with internal shorts. The charger does not indicate a bad battery and just keeps charging, heating up the batteries and the charger to the point of causing fire. Another better charger I have will indicate if the batteries are bad which is the only way I can find out.
I use these in my nitecore flashlight. They last all day at work, and they charge in just a few hours. Light goes from red to green.
I purchased this set for my UltraFire Cree T-6 flashlight and they work great. They will save me a lot of money in the long run.
