CR123A Rechargeable Batteries 8-Pack with Charger - Long Life Power

In this review of the FARSAIL CR123A Rechargeable Batteries 8-Pack, the bottom line is simple: this kit is for people who rely on CR123A-powered security cameras, flashlights or other devices and want a reusable, fast-charging replacement for single-use cells. The reviewer found the 800mAh 3.7V cells deliver reliable runtime, the charger handles eight batteries independently, and the built-in safety features make this a practical choice for continuous use in Arlo camera systems and similar equipment.

Key Features

• 800mAh Capacity: Provides extended run time over many single-use CR123A batteries, helping devices like security cameras and LED flashlights run longer between charges.
• Fast 2-hour Charge: The included charger uses a 2A charge current to refill batteries in about two hours, reducing downtime for multi-battery setups.
• 8-Bay Independent Charging: Each of the eight slots monitors and charges independently so mismatched cells or differing states of charge do not delay the whole pack.
• Built-in Safety Protections: Charger and cells include circuitry to detect short-circuit, over-charge, over-current, over-voltage and reverse insertion for safer everyday use.
• Wide Compatibility: Marketed as a direct replacement for a broad list of single-use 123 and 123A designations, making swaps straightforward for many devices.
• Endurance Claim: Manufacturer states cells retain up to 70% capacity after 500 full cycles, translating to long-term value versus disposable batteries.

Who It's For

This kit is a good fit for homeowners and small businesses that run multiple Arlo-compatible security cameras or compact LED flashlights and want to cut waste and operating cost by using rechargeable CR123A cells. Photographers and hobbyists who use devices that accept CR123A batteries will also appreciate the quick recharge and eight-slot capacity.

It is less suited to users who only need occasional backup cells or who prefer OEM camera batteries supplied by their camera maker; if you use a single device infrequently, a smaller or single-bay charger may be a simpler choice.

Pros & Cons

Pros

• Good runtime from the 800mAh 3.7V cells compared with single-use CR123A options.
• Fast 2-hour charge and independent monitoring for each of the eight bays keeps many devices operational with minimal downtime.
• Comprehensive safety circuitry in both cells and charger reduces risk of overheating or damage during repeated charging cycles.

Cons

• Actual runtime will vary by device and usage; heavy-duty devices may still need frequent recharges.
• These are larger-capacity lithium rechargeable cells, so users must confirm device compatibility before replacing single-use CR123A cells.
