DULEX 12-Pack Rechargeable 123A Batteries with Fast Charger - Long

In this review the DULEX 12-Pack 123A rechargeable batteries and charger are evaluated for people who use Arlo security cameras, LED flashlights, and other CR123A devices. The single biggest reason to consider this kit is the combination of high usable capacity and rapid recharge: these 3.7V NiMH 800mAh cells are designed to retain up to 70% capacity after 600 cycles and the charger refills a set in about 1.5 hours, which makes them a practical replacement for disposable CR123A cells in continuous-use security and lighting setups.

Key Features

• High cycle life: The cells retain up to 70% of original capacity after 600 full charge/discharge cycles, reducing long term replacement costs compared to disposables.
• Fast charge technology: The included charger delivers a 2A charge current and can refill batteries in about 1.5 hours so downtime between uses is minimal.
• Independent 4-bay charging: The charger monitors and charges each of the four installed batteries separately, so mixed charge states are handled safely.
• Wide application compatibility: These CR123A replacements are compatible with Arlo VMS3130, VMC3030, 3200, 3330, 3430 and 3530 cameras, plus flashlights and other electronics that accept 123A cells.
• All-weather performance: The batteries are specified to perform in a wide temperature range, helping maintain reliable power for outdoor security gear.

Who It's For

This pack is aimed at owners of Arlo HD security camera models listed above who want to cut running costs and waste associated with disposable CR123A batteries, or anyone who regularly uses high-drain LED flashlights and needs a rechargeable solution with fast turnaround. The 12-pack plus charger setup is also convenient for small operations or households with multiple devices to keep running.

Buyers who need a single off-brand cell for rare or low-drain uses may prefer a smaller kit or nonrechargeable cells, and those requiring higher nominal voltages than 3.7V NiMH chemistry should check device compatibility first. Also note the manufacturer recommends fully charging before first use.

Pros & Cons

Pros

• Long lifecycle that can replace many single-use CR123A batteries and reduce waste.
• Fast 1.5-hour charge with 2A current and per-bay monitoring for flexibility.
• High capacity 800mAh cells suited to frequent camera or flashlight use.
• Charger meets common safety standards (UL/CE/FCC/RoHS) for peace of mind.

Cons

• These are 3.7V NiMH rechargeable cells and users must confirm device compatibility before switching from nonrechargeable 3V lithium cells.
• The kit requires an initial full charge before first use, which adds a small setup step.

Our Verdict

The DULEX 12-Pack 123A rechargeable kit is a solid value for anyone running Arlo cameras or frequently used CR123A flashlights because it combines useful 800mAh capacity, fast charging, and a long rated cycle life that will lower replacement cost and waste over time. It is a practical, cost-conscious alternative to single-use CR123A cells for users who confirm their device accepts rechargeable 3.7V cells.

Frequently Asked Questions

Will these work in my Arlo camera?
Yes, they are listed as compatible with Arlo VMS3130, VMC3030, 3200, 3330, 3430 and 3530 models, but always confirm your camera accepts rechargeable 3.7V cells.

How many batteries can be charged at once?
The included charger charges up to four batteries at a time and monitors each bay independently.

How long before I need to replace them?
The cells are rated to retain about 70% capacity after 600 full charge/discharge cycles, offering the equivalent runtime of many disposable cells before replacement.
