16340 (RCR123) Battery & Charger – CR123A-Sized Rechargeable Li-ion Cells + Dedicated Chargers, Sustainable Power for Tactical Gear
Welcome to our 16340 (RCR123A) Battery & Charger collection. The 16340 lithium-ion cell (approx. 16mm diameter × 34mm length) is the rechargeable Li-ion version of the standard CR123A primary lithium battery. Sharing virtually identical dimensions, it delivers a 3.7V nominal voltage and usable capacities from 500mAh to 900mAh—the ideal sustainable alternative to expensive disposable CR123A cells for power-hungry tactical and professional equipment. This collection offers a full range of 16340 cells—High-Capacity NMC, High-Drain IMR/INR, and inherently safe LiFePO₄—along with dedicated Li-ion chargers compatible with 16340/18350/18650 and more. Ideal for tactical flashlights, laser sights, night vision devices, rangefinders, digital cameras, medical equipment, and various professional portable instruments.
Core Advantages of 16340 Batteries
- Standard CR123A Size – Perfect Compatibility: Approximately 16mm × 34mm—virtually identical to disposable CR123A batteries. Direct drop-in replacement for most CR123A-powered devices.
- Rechargeable – Drastically Reduce Operating Costs: Supports 500–1,000+ charge/discharge cycles. Disposable CR123A batteries are expensive; using rechargeable 16340s can save over 90% on battery costs.
- High Voltage Platform: NMC/IMR versions deliver a nominal 3.7V (full charge 4.2V)—approximately 1.2× the voltage of disposable CR123A (3.0V). Some devices may require voltage compatibility verification.
- High Discharge Capability: IMR/INR high-drain models support 2A–5A continuous discharge with pulse currents up to 8A—ideal for tactical flashlight turbo modes and laser devices.
- Flexible Chemistry Options: Available in high-energy NMC, high-drain IMR/INR, and inherently safe LiFePO₄ (3.2V) formulations.
- Low Self-Discharge: Monthly self-discharge as low as 3% ensures readiness after extended storage.
Core Advantages of 16340 Dedicated Chargers
- Precision Charging Management: CC/CV profile with automatic battery type detection (Li-ion/LiFePO₄) and auto-termination to prevent overcharging.
- Multiple Safety Protections: Overcharge, over-discharge, overcurrent, short-circuit, reverse polarity, and overheat protection.
- Wide Size Compatibility: Supports 16340, 18350, 18650, 18500, 14500, and more—one charger for multiple formats.
- Independent Charging Channels: Multi-bay chargers control each slot independently—mix cells of different charge levels and sizes.
- LCD Digital Display: Real-time monitoring of voltage, current, and charged capacity.

⚠️ 16340 Battery & Charger Safety Guidelines
- Voltage Compatibility – Special Attention Required: 16340 nominal voltage is 3.7V (full charge 4.2V), whereas disposable CR123A nominal voltage is 3.0V. Inserting a 16340 into voltage-sensitive devices may cause overvoltage damage or malfunction. Always consult the device manual to confirm compatibility with 3.7V RCR123A rechargeable batteries.
- Do Not Mix Chemistries: 3.2V LiFePO₄ and 3.7V NMC/IMR cells cannot be mixed or charged with the same settings. Verify charger mode before charging.
- Use a Dedicated Li-ion Charger: 16340 cells require a Li-ion-specific charger. Do not use NiMH/NiCd chargers.
- Avoid Over-Discharge: Stop discharging when voltage drops below 2.5V–2.8V (NMC/IMR) or 2.0V–2.5V (LiFePO₄). Recharge promptly.
- Avoid Short Circuits and High Temperatures: Do not short the terminals. Keep away from fire, heat, and moisture.
- Discontinue if Damaged: Stop using cells with torn wraps, dents, or leakage. Recycle responsibly.
