- Wide Size Compatibility with Secure Fit: At only 44mm long—21mm shorter than an 18650—10440 cells require chargers with adjustable sliders or short-cell compatibility. All chargers in this collection securely hold 10440 cells for reliable contact and uninterrupted charging.
- 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 10440, 14500, 16340, 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.

⚠️ 10440 Charger Safety Guidelines
- Confirm 10440 Size Compatibility: Some 18650 chargers cannot securely hold 44mm-long 10440 cells. Verify product specifications before purchase.
- Select Appropriate Charge Current: 10440 cells have small capacity and should be charged at 0.1A–0.3A. 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.
