123A Rechargeable Batteries 16-Pack with Charger - Long Lasting Power

In this review of the 123A Rechargeable Batteries 16-Pack with Charger, the bottom line is simple: it is intended for people who want a reusable, camera-ready power solution that reduces waste and operating cost. The pack is tailored especially for Arlo HD security cameras but also suits flashlights and other electronics. The single biggest reason to buy is the combination of high capacity 3.7V NiMH 800mAH cells and a fast, multi-bay charger that lets users recharge many batteries quickly and safely for repeated camera deployments.

Key Features

• High capacity: The 3.7V NiMH 800mAH cells provide extended runtime suited to security cameras and devices that need steady power.
• Fast charging: The included charger supports about a 2-hour charge time at 2A and can charge up to eight batteries concurrently for rapid turnaround.
• Safety protections: Built-in fault and heat protection in both batteries and charger guard against over-charge, over-current, over-voltage, short-circuit and reverse direction.
• Wide compatibility: Compatible with Arlo VMS3130, VMC3030, VMK3200 and other CR123A devices such as LED flashlights and alarm systems.
• Reusable and economical: Cells can be charged up to 600 times, cutting down on disposable battery waste and long-term costs.
• Complete kit: The set ships with 16 batteries, one charger, USB cable and adapter so it is ready to use after the initial full charge.

Who It's For

This pack is a good match for homeowners and small business owners who use Arlo or other CR123A-based security cameras and want to avoid frequent battery purchases. It also fits hobbyists who rely on LED flashlights or other electronics where rechargeable CR123A cells are supported.

It is less suitable for users who need OEM-branded cells with explicit manufacturer certification for specialized medical devices, or for those who cannot charge batteries on site and insist on disposable 3V lithium CR123A cells instead. Also, first use requires a full initial charge before deployment.

Pros & Cons

Pros

• Long-lasting 800mAH capacity provides good run time for cameras and lights.
• Fast 2-hour charging and an 8-bay independent charger reduce downtime between uses.
• Robust safety features and compliance with UL/CE/FCC/RoHS improve reliability.
• Excellent value when considering the ability to recharge up to 600 cycles.

Cons

• Customer reports on battery life are mixed, with some users experiencing poor hold after use.
• The NiMH chemistry requires a charger and initial full charge, so it is not a direct drop-in replacement for non-rechargeable 3V lithium CR123A cells in every scenario.
