18650 rechargeable batteries are high-capacity batteries 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. Fenix’s 18650 batteries have a guaranteed lifespan of 500 charge cycles. This means that the battery will recharge to at least 75% of its original battery capacity 500 times over. Compared to single-use batteries, rechargeable batteries are both cost-efficient and more useful for the consumer, offering extended runtimes and capacity on a single charge. Not only that, they are also beneficial to the environment by limiting the amount of single-use products and discarded chemicals. Overall, Fenix’s 18650 batteries offer a safe, time and cost-effective solution for anyone looking to power their high-lumen flashlights. Always make sure to purchase li-ion batteries from an established and trusted distributor to avoid purchasing faulty, potentially dangerous products.

The USB versions will work in all of the current models that utilize a li-ion 18650 battery—in older Fenix lights these may not work. 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 Products

Enquiry

I have a PD35 1700 lumens that come with ARB-L18-2600U - 18650 battery.
I plan to buy another battery for backup, i wondering is the ARB-L18-3500U – 18650 compatible?

Yes it is. You can use any of our button top 18650 batteries in that light.

Waste of money

My PD35 that had very little use died. I am very unhappy with the quality of your products. I bought an Olight instead.

did you contact warranty about the PD35? I don't see an order under your name for the PD35. Warranty is done through the distributor of your specific light, but our team can determine what service center you need to work with. They will just need the 11 digit alpha numeric serial number from the light to figure that out. You can reach our warranty team at 888-775-9996 ext 1, or warranty@fenixlighting.com

Great Service

I believed my flashlight Batt was dead. Ordered another and the new Batt came very fast. It turns out that it was not the cause for failure of the Flashlight. All it needed was a proper cleaning with Rubbing Alcohol. BUT , at least I have another Batt that's fully charged and ready to go when the present one needs recharging.
