    Love it.

  12. Richard Pawl (verified owner)

    Happy with my 1400 lumen hard hat light. It’s better than anyone else’s. And having that spare battery I bought from you gives me added confidence because the batteries are already good and don’t drain too fast like a stupid ass streamlight. My next purchase will be a tactical flashlight like your 3000 lumen model. Can you give me a good deal on this?

  13. Joshua N. (verified owner)

    Great flashlights need great batteries. Love the individual plastic containers they came in, much more convenient than the previous method of shipping in foam.

  14. Larry N. (verified owner)

    Upgraded battery for my first UC35.

  15. Wilbur Andrews (verified owner)

    Shipping is too slow, several times slower than Amazon. I get Amazon in two days. Fedex takes over a week – that’s bad

      Please note your order for this item was placed on a Sunday. Our employees have weekends off. We work standard M-F hours so that we can time with our family and friends on weekends. Your order shipped on Monday. You choose the free shipping option, which explicitly states 3-5 business days. This ships via USPS, which, due to COVID is occasionally taking longer. Regardless, your package was delivered to you on Friday, 4 days after it left our facility and within the 3-5 day range we provide. It left our facility on the first working day after you placed your order. However, once it leaves our facility, which it did rather quickly, it is out of our hands on how long it takes the USPS to deliver the package. They do have a note on their website that states “ALERT: DUE TO LIMITED TRANSPORTATION AVAILABILITY AS A RESULT OF NATIONWIDE COVID-19 IMPACTS, PACKAGE DELIVERY TIMES MAY BE EXTENDED” We do have paid options for expedited shipping.

  22. John Caskey (verified owner)

  23. Bruce Baumel (verified owner)

    Illuminating your lighting requirements is dependent on an excellent power source and Fenix is that source.

  24. Ryan (verified owner)

    Nice batteries and long lasting.

  25. Rod Ferguson (verified owner)

    Good battery and light

  26. Bob Chauncey (verified owner)

    Also nice and easy to charge, but need charger, while Fenix ARB-L18-3500U has port to charge and likely easier to do.

  27. Bradley Rogers (verified owner)

    Good to have as a backup power source on rechargeable headlamp.

  28. Anonymous (verified owner)

    Great battery..

  29. Melissa M. (verified owner)

    I got tired of seeing all of the weird knock off replacement batteries on Amazon, so I came back to Fenix and was excited to see that there is a rechargeable battery for my PD35. So excited and pleased with this!

  30. Wendy Osborn (verified owner)

    Package came opened, battery will not hold a charge. Emailed asking for a resolution, they never responded 🙁

    • Dianne

      I have asked warranty to contact you. That’s really odd.

  31. Myles Rogers (verified owner)

    I thought it had a teceptical on battery for charging

  32. Thomas (verified owner)

    Great

  33. Al (verified owner)

    I had a problem with my new fenix headlamp. The company immediately sent me a new one and I was so impressed I bought the higher capacity battery to go with it. Both are working perfectly. Couldn’t be happier.

  34. Anonymous (verified owner)

    I have four Fenix lights using the 18650. Two TK’s, a lantern, and an HM65R headlamp. I love having a one battery system. A double charger which keeps the batteries, but that only comes out once or twice a month as the 3400/3500 mAh batt’s last for a while! Overall this is an excellent unit.

  35. David D. (verified owner)

    Love it

  36. Chris A. (verified owner)

    The two batteries that were purchased have done there job and more I no longer have to be carrying around a hand full of regular C123 Batteries. They work great.

  37. David B. (verified owner)

    Good batteries, they provide plenty of power and last a long time.

  38. Tim C. (verified owner)

    Long life, works great

  39. Michael M. (verified owner)

    The contact on the phone was very helpful even though my light was not bought from their site. I chose to buy the battery instead of the hassle of warranty from another vendor. I will buy Fenix again, but only from their site for the great service

  97. GREGORY MUMMAH

    Very good battery – works as advertised. 3500mah is definitely the way to go

  98. Wayne (verified owner)

    These batteries provide a uniform and reliable power output for my Fenix lights. I use these in a variety of Fenix products including headlamps, regular flashlights and camping/utility lights. This is my preferred battery since it provides the longest run time.

  99. Matthew K. (verified owner)

    Great battery! Long lasting!

  100. John J. (verified owner)

    Works as advertised. It is a bit pricy compared to other 18650’s on the market. But at least with Fenix, I know that I’m getting a good product

  101. Timothy M. (verified owner)

    I wasnt sure that this w/b an improvement over the 2600mAh, but it is! Worth it

  102. Eric M. (verified owner)

    I own a termite inspection company and so I have many Fenix flashlights and accessories. These are the best and brightest flashlights we have ever used and very durable. The batteries last a very long time as we use professionally 5 days a week. When we do need service they stand behind the product. I could not more highly recommend this product.

  103. Anonymous (verified owner)

    They seem to hold up pretty well. I haven’t really had time to put these batteries through the wringer yet…

  104. EZRA (verified owner)

    Excellent battery.

  105. Sergeant Frank C. (verified owner)

    Solid purchase.

  106. Paul Carroll (verified owner)

    Outstanding battery. I’m buying some for my coworkers

  107. Richard

    I can’t say enough about the charger. I expected a plastic step-on-me-once-and-I’m -dead charger. This thing is tough! I don’t know what it is made out of but I am so impressed I’m getting one for my step-son.
    I use mine (HL60R) professionally (daily) and made the mistake of taking it goose hunting once and my step-son really loved it. He got one for Christmas and now getting a charger. Inexpensive and sturdier than any charger I have ever purchased at any price.

    Friends gave me a Fenix UC40UE tactical light for my birthday, and I am hooked on Fenix Quality. Just returned from a 12 day elk in the Wyoming back country and this light was outstanding, while using the FENIX 3500 amh rechargeable batteries. 900 Lumens from this small compact light it awesome!! Outstanding quality!! I just ordered the new version of the TK75 and cannot wait to get my hands on this one. Fenix service is also outstanding and they are always helpful when I call…. helpful and full of the correct information! Keep up the good work! Fenix quality is second to none!!!!

  109. Kevin (verified owner)

    Just got the batteries, they look good and are charging now. This review is primarily for the Fenix brand and level of service. I ordered two of these batteries and a two Bay charger. When I received the order there was a 4 Bay digital charger and a note stating that they were out of stock on the two Bay and to please accept the free upgrade. I am highly impressed, Fenix didn’t have to do that but rather than make an ordeal out of it they not only got me what I needed but gave me more than I had asked for. I appreciate this greatly as I am going camping in a few days and don’t have time to order another from somewhere else without having to pay overnight shipping. Fenix quality is outstanding and they’re service to customers matches it. Im now a customer for life
