CR123A Rechargeable Batteries 16-Pack with 4-Bay Charger - Fast Charge

In this review the FARSAIL CR123A Rechargeable Batteries 16-pack is evaluated for users who rely on CR123A-powered security cameras and LED flashlights and want a reusable, higher-capacity alternative to disposables. The single biggest reason to buy is the combination of an 800mAh capacity with a dedicated 4-bay USB charger that offers about 1.5-hours fast charge at 2A, which means less downtime for devices like Arlo cameras. The pack and charger aim to balance run time and safe charging controls for continuous home security or frequent flashlight use.

Key Features

• High capacity: The 3.7V, 800mAh cells provide longer run time per cycle compared with many single-use CR123A batteries, reducing how often replacements are needed.
• Fast charging: The included charger supports roughly 1.5-hours charge time at a 2A current for quick turnarounds when batteries run low.
• Safety protections: Each cell and the charger include built-in fault and heat protection and fail-safe circuitry to help prevent over-charge, over-voltage, over-current, short-circuit and reverse polarity events.
• Four-bay compact charger: The small charger tops up four batteries at once and uses a bright LCD display so users can see charging status at a glance.
• Wide compatibility: Batteries and charger are compatible with Arlo VMS3130, VMC3030 and other listed camera models as well as many LED flashlights and small electronics.
• Complete pack: Sixteen rechargeable CR123A cells are supplied with the charger, suitable for multi-camera setups or extended flashlight use.

Who It's For

These batteries are best for homeowners or technicians running multiple CR123A devices such as compatible Arlo security cameras and LED flashlights who want rechargeable cells with clear charging controls and built-in safety. The 16-pack suits multi-camera installations or anyone who replaces batteries frequently and prefers to keep spares charged and ready.

Those who should look elsewhere include users who need single-use behavior (this charger must not be used on disposable CR123A cells) or people who cannot provide a USB power source for the charger, since a wall adapter is not included. Also, if absolute OEM compatibility is required, verify device acceptance of 3.7V rechargeable cells before switching from non-rechargeable cells.

Pros & Cons

Pros

• High 800mAh capacity extends run time in cameras and flashlights compared with many disposable options.
• Fast 1.5-hour charge time at 2A and an LCD status display reduce downtime and make monitoring easy.
• Comprehensive safety features in both cells and charger protect against common charging faults.

Cons

• Charger relies on a USB cable without a supplied wall adapter, so a separate USB power source is required.
• Rechargeable 3.7V chemistry differs from single-use CR123A voltages, so some devices may not accept them without manufacturer approval.
