The Fenix ARB-L16-700UP 16340 lithium-ion battery is specifically designed for high current, high drain devices and makes a great accessory add for all current Fenix 16340 (RCR123) powered lights. The simple explanation of the benefits of this battery used in Fenix high drain devices is that they will last longer at their highest performing levels by sustaining a higher voltage. It also includes a protection circuit in the anode to help prevent short circuits, over charge/discharge and over heating. This battery can quickly be charged without the need for a separate charger via it’s USB port. This not only saves you money from purchasing a charger, but also convenience of not having to carry around another device. It is designed to work with: PD25, LD15R, E18R, E16, E15 and HM50R. A micro-USB charging cord is NOT included.
Does not hold a charge anywhere near as long as non-rechargeable, even when idle. After 3 or 4 days of non-use, battery is dead. I suppose I could be more diligent about charging for EDC, but my previous Fenix would go for weeks or longer than a month on a single CR123 with daily use.
These batteries are great for my headlamp. I have four that I can replace for extended use and the mini USB charge allows easy recharge wherever I am. Highly recommended

These are very handy. Great to keep in your bag when you are out and about. It can be charged from your car charger. Save yourself headaches when you are traveling and when you are at home.

Simplified Power - 700U Rechargeable Battery Tactical Ambassador, Erik W. gives his thoughts When picking a light for tactical or EDC use it's easy to overlook charging style or even battery. Features like size, power and rail adoption often eclipse some critical features. Even more so if you need a backup light (everyone should) or…

Nice and compact. Works even in my smallest 1xCR123 light (though it’s a tight squeeze between the contacts).

Battery seems to drain a bit too quickly when on high power, compared to a CR-123.

Only wish they could fit a USB-C connector instead.
