123A Rechargeable Batteries and Charger 16-Pack - Fast Charge Power

In this review the FARSAIL 123A Rechargeable Batteries and Charger are tested as a budget-friendly replacement for single-use CR123A cells. The bottom line is simple: this 16-pack plus charger is for anyone who needs frequent, high-drain power for security cameras, LED flashlights, or similar devices and wants to cut waste and running costs. The most compelling reason to buy is the combination of 800mAh capacity and a two-hour fast charge cycle that makes these batteries a practical, reusable alternative to disposable cells.

Key Features

• Compatibility: Works with Arlo style security cameras and other electronics, making swaps easy for common camera and flashlight setups.
• Capacity: Each cell is 800mAh at 3.7V, giving solid runtime for many LED flashlights and camera models designed for 123A cells.
• Longevity: Cells retain up to 70% of capacity after 600 cycles, which translates to long-term cost savings versus disposable batteries.
• Fast Charging: The included charger uses a 2A charge current and finishes a charge in about two hours, so spares are ready quickly.
• Safety Certifications: Built-in fault and heat protection and certifications like UL, CE, FCC, and RoHS reduce risk in daily use.
• Value Pack: Sixteen batteries plus a charger and a one-year warranty simplify replacement and maintenance needs.

Who It's For

The FARSAIL 123A 16-pack is best for homeowners or small businesses running multiple security cameras or those who depend on LED flashlights and want rechargeable convenience. It suits users who cycle through batteries often and prefer a fast top-up time between shifts or patrols.

It is less well suited to devices that require exact original CR123A chemistry specs or to users who never recharge batteries and prefer to store single-use cells for long-term low-use scenarios. If absolute original-brand compatibility is required, check device recommendations first.

Pros & Cons

Pros

• Good value per cell when you factor in 600 recharge cycles and retained capacity.
• Fast two-hour charge with a clear LED indicator that shows red while charging and green when complete.
• Multiple safety features and common certifications that increase day-to-day reliability.
• Large pack size reduces the need for frequent repurchasing and covers several devices at once.

Cons

• Customer reports on battery life are mixed; some units may not hold charge as long as others in real-world use.
• Not a direct drop-in for every device labeled CR123A without checking physical and voltage compatibility first.
