16340 (RCR123) Charger – Dedicated Li-ion Chargers for CR123A-Sized 16340 Cells, Precision & Safe Charging Management

Welcome to our 16340 (RCR123) Charger collection. The 16340 battery (approx. 16mm diameter × 34mm length) is the rechargeable Li-ion version of the standard CR123A primary lithium cell, with a nominal voltage of 3.7V, full charge of 4.2V, and typical capacities of 500mAh–900mAh. Its compact size and the need for precise charge termination—especially for high-drain models—demand chargers with excellent size compatibility, accurate charging current, and robust safety protections. This collection features high-quality Li-ion chargers specifically designed for or perfectly compatible with 16340 cells—ranging from single-bay portable chargers to multi-bay digital chargers—ensuring your 16340 batteries are recharged in the safest, most efficient, and most precise manner.

Core Advantages of 16340 Chargers

Perfect Size Compatibility with Secure Fit: At only ~34mm long—about 31mm shorter than an 18650—16340 cells require chargers with adjustable sliders or compact bay designs. All chargers in this collection securely hold short 16340 cells for reliable contact and uninterrupted charging.
Precision Low-Current Charging: With typical capacities of 500mAh–900mAh, 16340 cells charge best at 0.25A–0.5A. These chargers support adaptive or manually adjustable low currents to prevent damage from excessive current and extend battery lifespan.
CC/CV Smart Charging Management: Utilizes constant-current/constant-voltage (CC/CV) charging profile with automatic battery state detection. Charging terminates precisely at 4.2V ±0.05V (Li-ion) or 3.65V (LiFePO₄), effectively preventing overcharging and ensuring battery safety.
Multiple Safety Protections: Built-in overcharge, over-discharge, overcurrent, short-circuit, reverse polarity, and overheat protection for comprehensive charging safety.
Independent Charging Channels: Multi-bay chargers control each slot independently—mix 16340, 18350, 14500, 18650, and other cell sizes with different charge levels without interference.
LCD Digital Display: Real-time monitoring of charging voltage, current, accumulated capacity, and internal resistance—charging status at a glance.

⚠️ 16340 Charger Safety Guidelines

Confirm 16340 Short-Body Compatibility: Some 18650 chargers cannot securely hold 34mm-long 16340 cells. Verify product specifications before purchase.
Select Appropriate Charge Current: 16340 cells charge best at 0.25A–0.5A. If manual setting is available, select a low current; if adaptive, ensure minimum current ≤0.3A.
Distinguish Battery Chemistry: 3.7V Li-ion (full charge 4.2V) and 3.2V LiFePO₄ (full charge 3.65V) require different modes—do not mix.
Avoid High-Temperature Charging: Keep away from heat sources and direct sunlight; ensure good ventilation during charging.
Remove After Full Charge: Although chargers feature auto-termination, prolonged connection to power may still affect battery longevity. Remove batteries promptly after charging.
