17350 Charger – Dedicated Li-ion Chargers for 17mm Diameter Compact Cells, Precision & Safe Charging Management

Welcome to our 17350 Charger collection. The 17350 battery (approx. 17mm diameter × 35mm length) is a compact cylindrical Li-ion cell positioned between the common 16340 and 18350 sizes, with a nominal voltage of 3.7V, full charge of 4.2V, and typical capacities ranging from 400mAh to 850mAh[reference:19][reference:20]. Due to its unique 17mm diameter and 35mm length, it is often used in space-constrained devices such as e-cigarettes, electric toothbrushes, Bluetooth speakers, power tools, and various portable electronics[reference:21]. This collection features high-quality Li-ion chargers specifically designed for or perfectly compatible with 17350 cells—ranging from single-bay portable chargers to multi-bay digital chargers—ensuring your 17350 batteries are recharged in the safest, most efficient, and most precise manner.

Core Advantages of 17350 Chargers

Perfect Size Compatibility with Secure Fit: At only ~35mm long and ~17mm in diameter, 17350 cells require chargers with adjustable sliders or compact bay designs. All chargers in this collection securely hold 17350 cells for reliable contact and uninterrupted charging.
Precision Low-Current Charging: With relatively small capacities, 17350 cells charge best at 0.2A–0.5A[reference:28]. These chargers support adaptive or manually adjustable low currents to prevent damage from excessive current and extend battery lifespan. Many smart chargers support charging currents as low as 100mA to effectively protect small-capacity batteries[reference:29].
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, effectively preventing overcharging and ensuring battery safety. Some chargers can also automatically activate over-discharged batteries[reference:30].
Multiple Safety Protections: Built-in overcharge, over-discharge, overcurrent, short-circuit, reverse polarity, and overheat protection for comprehensive charging safety. Many chargers use fire-retardant materials and have passed multiple safety certifications[reference:31].
Independent Charging Channels: Multi-bay chargers control each slot independently—mix 17350, 18350, 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.

⚠️ 17350 Charger Safety Guidelines

Confirm 17350 Short-Body Compatibility: Some 18650 chargers cannot securely hold 35mm-long 17350 cells. Verify product specifications before purchase.
Select Appropriate Charge Current: 17350 cells charge best at 0.2A–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.
