Good batteries and flashlight.
Edward S. (verified owner) –
The best 18650’s hands down! Used for emergency management and absolutely the most reliable long lasting of many other brands previously used. They are the only option in Fenix lights if you want the best light for long run utilization!
James M. (verified owner) –
I got the 2600 mah for my bike light since I will know I will be charging these a lot and rotating batteries. Just me, but I use the 3500 mah batteries in regular flashlights that I don’t charge as much, due to price

You can’t really “review” batteries without many months or years of use.
However, upon initial purchase and use (one month), all I can say is expect extremely long charging times. The times represented by the company are no where near true.
In fact, charging times are about twice what is marketed. I used a high powered USB point to ensure the best times, as I had already read about the charging time issue from another review. That reviewer was spot on.
Otherwise, the batteries seem to be extremely well made and of great quality. Are they worth Fenix’s extra mark up? That’s for you to decide. I’m on the fence until I see some true run times.
Anonymous (verified owner) –
Great service and easy to charge battery!
I will advise that while I bought 2 batteries , the display lights as they charged differed (one stayed on and one didn’t) but both still charged and powered the flashlight well!

John Petersen (verified owner) –
Having owned many different 18650 batteries from different companies you start to see why the cheaper ones are less expensive. I can say without hesitation that Fenix’s 18650 batteries are top quality and will last you a long time with excellent performance.
Jonathan Keith (verified owner) –
Bought these as spare/additional batteries for a range of fenix lights I have. I went with the 3500mAh batteries to give extra time to my lights’ battery life.
William Long (verified owner) –
Have only used one so far but it is working fine.
Jeremy F. (verified owner) –
I was very pleased with the service and the product, I will only use Fenix from here on out.
James Lucas (verified owner) –
These batteries will make your TK 75 light up the night with its unbelievable brightness! Wanna kill a vampire with your blinding rays? Use this kick butt battery with its Uber cool recharge port and LED lights and give the undead something to really hate you by. Wanna hold the thunderbolt of lightning (very, very frightening!). Be like Galileo and get your man paw on this beast of a battery to power your thunder of Thor flashlight. Cheers

Charges easily and holds a charge for a long time.

I’m returning for another order. The first two 3500mAh worked and working great – at least one of them. I can’t find the 2nd one atm . . . misplaced or “borrowed”. Finally, honestly rated 18650 cells, not exaggerated high mAh claims. With protection circuitry, and the USB rechargeability for me is added assurance I can keep power available when away. I always use a quality at-home plug-in recharger. That’s how I KNOW these are honestly rated, as my recharger will easily pick out the dishonest ones.

Light, no heavy battery pack hanging off the back of your head and no tail!! and bright…bring your sunglasses and tanning lotion but never hot. LEDS are awesome.

I purchased your Fenix UC35 flashlight a few months ago. When I went to recharge the battery it still did not work, so I bought another battery. It would NOT charge up either. So I now have two batteries and a flashlight that don’t work. I’m a volunteer Sheriff and rely on my flashlight at night and this one fits my leather light holster, Now I’m going to have to spend all that money again (out of my pocket) on another product… NOT A FENIX. NOT a happy customer.
Dianne (store manager) –
Susan – unfortunately there was a bad batch of batteries with the UC35. I have asked warranty to contact you about getting you a good battery.

Lost a PD35 2014 Edition. Had too many flat top batteries to purchase PD35 V2. Lucky PD35 Tac uses flat top batteries. Bought 2 flashlights but needed to replace the battery that was in the lost flashlight. In that they don’t sell flat top batteries anymore, this battery performs just as good and will be usable in other flashlights not using flat tops should I need to buy another flashlight in the future.
