Fenix ARB-L16-700 Li-Ion battery 16340 3.7V 700mAh (protected)

The Fenix ARB-L16-700 is a high-quality lithium-ion battery in size 16340, also known as RCR123A. It has been specially developed for the operation of high-performance torches and other electronic devices that require high energy density and voltage. With a capacity of 700 mAh and a nominal voltage of 3.7 V, this battery offers a powerful, rechargeable alternative to conventional CR123A primary batteries. The integrated protection circuit and the special anode design ensure maximum safety.

Highlights at a glance

• High power density: 700 mAh capacity for long runtimes in compact devices.
• Integrated protection circuit: Protection against overcharging, deep discharge and short circuit built directly into the anode area.
• Robust construction: Steel casing protects against mechanical impact and prevents short circuits from shocks.
• Long service life: Designed for up to 500 charging cycles with correct care.
• Rechargeable alternative: Replaces CR123A batteries in suitable devices and reduces operating costs.

Maximum safety through innovative technology

A prominent feature of the Fenix ARB-L16-700 is the placement of the protection circuit (PCB) in the anode (positive terminal) area. This construction, combined with robust riveting, protects the battery more effectively from drops and shocks than conventional PCBs on the cathode base. In addition, pressure relief valves prevent a build-up of gas inside, ensuring operational safety under even extreme conditions or malfunctions.

Powerful and durable

The ARB-L16-700 uses modern lithium-ion technology to completely eliminate the memory effect. You can recharge the battery at any time, regardless of its current charge state. With a service life of approx. 500 charge cycles, this battery provides a sustainable and economical solution, especially for users who make intensive use of their torches or devices. The low self-discharge ensures that the battery is ready for use even after storage.

Compatibility and areas of use

This battery is of the 16340 size and is mechanically compatible with devices that use CR123A batteries. Due to the higher voltage of 3.7 V (compared to 3.0 V for CR123A batteries), it is ideal for modern LED torches from Fenix (e.g. PD25, PD22 Ultimate Edition) and other manufacturers that are expressly approved for operation with Li-Ion batteries.

FAQs about the Fenix ARB-L16-700

Can I use this battery as a replacement for any CR123A battery?

No, not in every case. This battery has a voltage of 3.7 volts, whereas a standard CR123A battery has 3.0 volts. You may only use this battery in devices that are expressly approved by the manufacturer for the higher voltage of lithium-ion batteries (3.7 V / 4.2 V charging end voltage). Non-compatible devices may be damaged electronically.

Do I need a special charger?

Yes, you need a charger suitable for lithium-ion batteries in size 16340. We recommend using Fenix chargers or high-quality universal chargers that ensure the correct charging current and cut-off voltage.

What does "protected" mean for this battery?

"Protected" means that the battery features integrated electronics (PCB). This continuously monitors the cell and switches it off in the event of overcharging, deep discharge, or a short circuit. This greatly increases safety in daily use.

How should this battery be disposed of?

Batteries must not be disposed of in household waste. As a distributor of batteries, we are obliged to take them back, and you as the end user are legally obliged to return them. You can hand in old batteries free of charge at municipal collection points or in retail outlets.
