1C charging and 3C discharging, more than 85% of initial capacity after 300 cycles
Mechanical engineers designing premium electric toothbrushes and razors face constant pressure to shrink internal PCB space while maintaining long battery life. The 14280 Li-ion cell (1/2 AA size) is the definitive solution for these high-integration challenges. It offers significantly higher energy density than traditional Ni-MH alternatives, allowing for sleeker ergonomic designs without sacrificing power. This cell is engineered to handle high-frequency vibration loads, ensuring that motor torque remains constant from the first minute of use to the last, providing a superior user experience in the professional personal care market.
• Compact Form Factor: Standard 14280 dimensions (14x28mm) for maximum energy in restricted device housings.
• Stable Chemistry: 3.7V high-voltage platform with low self-discharge rate (<3% per month) for extended shelf life.
• Cycle Reliability: Purpose-built for daily recharge cycles with high capacity retention over hundreds of cycles.
• Automated Manufacturing: Produced via precision winding processes to ensure cell-to-cell consistency for batch QC.
• Integration Support: Available with customized nickel tabs and integrated PCM to accelerate time-to-market.
