14430 14280 lithium ion battery cell for electric toothbrush and razor 650mAh 3.7V long cycle life 3C discharge

Compact personal care devices often suffer from “power lag” as the battery drains, resulting in poor cleaning performance. The 14430 Li-ion cell (4/5 AA size) is engineered to solve this by offering a 3C discharge rate. This means it can consistently deliver up to 2A of current, maintaining the high-frequency vibrations required for professional-grade cleaning tools. For procurement managers, this cell offers the perfect balance between a small physical footprint and high-rate performance usually found in larger batteries, ensuring consistent motor torque.

• Optimal Power Balance: 3.7V 650mAh capacity with a 3C discharge rating for high-load motor efficiency.
• Long Cycle Retention: Advanced chemistry ensures 500+ cycles with minimal capacity degradation.
• Precision Manufacturing: Stringent internal resistance matching ensures every batch meets B2B specs.
• Global Certification: Fully compliant with IEC62133 and UL standards for premium international markets.
• Application Focus: Ideal for electric toothbrushes, shavers, and micro-medical diagnostic devices.
