18560 rechargeable batteries are the highest volume standard battery used in lighting products. The 18650 battery is a great alternative for products that utilize 2xCR123A disposable batteries. Not only are you being environmentally friendly by eliminating disposable batteries, but the 18650 battery also provides different levels of capacity for your exact need and is rechargeable. For example, you can get 30% more capacity out of a ARB-L18-3500 compared to a ARB-L18-2600. In addition, Fenix batteries are built with safety in mind. There are built in features to prevent short circuits, design multiple layers of protection and the new button-top design.
The high capacity 18650 Li-ion rechargeable batteries each provide protection circuits in the anode to help prevent short circuits, over charge/discharge and over heating. Each 18650 battery also includes pressure relief vents which expel waste gas in the rare case of an internal short circuit preventing an explosion. The USB versions will work in all of the current models that utilize a li-ion 18650 batteryโin older Fenix lights these may not work.ย A micro-USB charging cord is NOT included with the USB versions. See our wide range of products that accommodate the 18650 batteries: 18650 Fenix Productsย

I got three of the highest capacity ones available (3500mAh); they work great in my PD35, and they hold charge really well so far. I’ve had one in my flashlight for a couple of weeks now, and I’m not seeing any sign that it’s time to swap it out yet.
Each of my batteries came in a plastic case, and I discovered that the cases have tabs and slots on the sides, which let me connect all three together in a single unit. Very handy for keeping them from rolling around on a shelf or in a drawer.

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.

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.

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.

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.

Easy access to charger and very solid placement of charger (the charging port doesnโt wiggle when I plug into it). Very high quality wrap on battery too. Havenโt ran too many cycles with the batteries yet but I donโt foresee any issues given the quality of manufacturing Iโve seen so far.

I got three of the highest capacity ones available (3500mAh); they work great in my PD35, and they hold charge really well so far. I’ve had one in my flashlight for a couple of weeks now, and I’m not seeing any sign that it’s time to swap it out yet.
Each of my batteries came in a plastic case, and I discovered that the cases have tabs and slots on the sides, which let me connect all three together in a single unit. Very handy for keeping them from rolling around on a shelf or in a drawer.

The best 18650โs 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!

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 donโt 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 didnโt) but both still charged and powered the flashlight well!

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 Fenixโs 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.

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

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.

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.

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.
