About 16340 Batteries

Discover the Versatility of 16340 Batteries for Tactical and Medical Use

Need a compact yet powerful rechargeable battery? The 16340 battery, a lithium-ion standout, measures 16mm in diameter and 34mm in length, often serving as a CR123A alternative. With a 3.7V output and capacities around 700mAh, it’s a go-to for high-performance flashlights, cameras, and medical devices. Whether you’re gearing up for a tactical mission or ensuring medical equipment runs smoothly, the 16340 battery delivers durability and efficiency in a small package.

Why 16340 Batteries Are a Top Choice

The 16340 battery shines with its ability to replace non-rechargeable CR123A batteries, offering a rechargeable 3.7V solution. Its 700mAh capacity supports intense power demands, making it ideal for tactical gear and medical tools. With a lifespan of up to 800 cycles, it’s a sustainable option that reduces waste. For users needing reliable power in critical situations, this battery is a trusted ally.

Key Features and Specifications

  • Size and Compatibility: At 16mm x 34mm, it fits CR123A slots, perfect for compact devices.
  • Voltage and Capacity: Delivers 3.7V with around 700mAh for robust performance.
  • Rechargeable Durability: Offers up to 800 charge cycles with proper care.
  • Applications: Great for tactical flashlights, medical devices, and photography gear.

Benefits of 16340 Batteries

The 16340 battery’s high discharge rate and capacity make it a favorite for devices needing quick, strong power bursts. Its rechargeable design saves money and reduces environmental impact compared to disposable CR123A batteries. Users appreciate its reliability in rugged conditions, from night patrols to emergency medical use, making it a versatile and eco-conscious choice.

Real-World Performance

Imagine you’re on a night mission, relying on your tactical flashlight. A CR123A might burn out, but a 16340 battery keeps the beam steady. Medical professionals value its consistent power for portable defibrillators. Users highlight its ability to handle high-drain tasks, proving its worth in both professional and recreational settings.

Potential Downsides to Note

The 16340 battery isn’t flawless. Its 700mAh capacity offers less runtime than larger batteries like the 18650. Incompatible devices can suffer from its 3.7V output, so compatibility checks are a must. Over-discharge or improper storage can also reduce its 800-cycle life. With careful use, these drawbacks become minor hurdles.

Maintaining Your 16340 Batteries

Keep your 16340 battery in top shape with these tips. Use a lithium-ion charger suited for its specs to avoid overcharging. Store it in a cool, dry place at 50-60% charge for longevity. Protect it from heat or impact with a case, especially during travel. Follow these steps to enjoy its full cycle potential.

Ideal Uses and Compatible Devices

The 16340 battery excels in tactical flashlights, providing bright, long-lasting light for security or hunting. It powers medical devices like portable monitors with reliability. Photographers use it in compact cameras for extended shoots. If your gear supports this size, it’s a powerful upgrade worth considering.

Comparing 16340 Batteries to Alternatives

How does the 16340 compare? It outshines CR123A batteries with rechargeability and similar size. Against the 14500, it offers less capacity but a higher discharge rate for specific needs. Compared to the 18650, it’s smaller but less enduring. For compact, high-drain devices, the 16340 is a top contender when matched to your equipment.
