Digital Grade

Digital Grade

Digital-grade lithium-ion cells feature high reliability, long battery life, a wide operating temperature range and long service life. They are widely used in power tools, electronic toys, power banks, portable lighting, smart speakers and smart home devices.

Digital Grade
1

High reliability

Stable electrochemical performance across the full life of the cell, with tight internal resistance distribution from the sorting stage.

2

Long battery life

Energy densities up to 9.62 Wh per cell, giving longer runtime in the same device footprint.

3

Wide temperature application

Engineered for reliable operation in both cold-start and high-ambient consumer environments.

4

Long life

Designed for extended calendar and cycle life in stationary and intermittently used consumer products.

Power Grade

Power Grade

Power-grade lithium-ion cells deliver high-rate discharge capability up to 5.0C, low internal resistance and stable high-current output, ensuring reliable power for demanding applications. They are widely used in power tools, e-toys, RC models, vacuum cleaners and other high-power devices.

Power Grade
1

High reliability

Tight internal resistance control, with key models at 20–25 mΩ at first grade.

2

Long endurance

Sustained high-current output over the full discharge curve rather than a short peak burst.

3

Wide temperature applications

Performance maintained across cold mornings and hot operating environments.

4

High operating current

Continuous discharge rates of 3.0C as standard, with selected models rated to 5.0C continuous.

5

High-frequency vibration

Structural and electrode design tuned for the constant vibration of handheld and vehicle-mounted equipment.

6

Long life span

Long cycle life supported by the manganese cathode system and conservative charging profiles.
