Product Overview

The LNC651566 is a high-performance 3.7V lithium polymer ring battery designed for wearable and body-worn electronic devices. Featuring a 500mAh capacity and ring-shaped form factor, it is engineered to deliver stable power output in compact, curved-space installations.

With high energy density, low self-discharge, and long cycle life performance, this battery is well-suited for continuous operation in smart wearable systems where reliability and space efficiency are critical.

Long Cycle Life

Up to 500+ charge/discharge cycles under standard conditions.

High Energy Density

Provides strong energy output in a compact lightweight structure.

Low Internal Resistance

Polymer cells can achieve ultra-low resistance (down to 35mΩ in advanced designs), reducing energy loss.

Low Self-Discharge

Minimal capacity loss during long-term storage.

No Memory Effect

No need for full discharge before recharge.

Excellent Discharge Stability

Stable discharge curve with higher voltage platform due to gel polymer electrolyte.

Custom Shape Design

Supports fully customized geometries for OEM wearable integration.

Enhanced Safety

Pouch structure avoids explosion risk; swelling only under extreme conditions.
