    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!

    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.

    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.

    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

    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.

    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.

    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!!!!

    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
