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.
High reliability
Stable electrochemical performance across the full life of the cell, with tight internal resistance distribution from the sorting stage.
Long battery life
Energy densities up to 9.62 Wh per cell, giving longer runtime in the same device footprint.
Wide temperature application
Engineered for reliable operation in both cold-start and high-ambient consumer environments.
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.
High reliability
Tight internal resistance control, with key models at 20–25 mΩ at first grade.
Long endurance
Sustained high-current output over the full discharge curve rather than a short peak burst.
Wide temperature applications
Performance maintained across cold mornings and hot operating environments.
High operating current
Continuous discharge rates of 3.0C as standard, with selected models rated to 5.0C continuous.
High-frequency vibration
Structural and electrode design tuned for the constant vibration of handheld and vehicle-mounted equipment.
Long life span
Long cycle life supported by the manganese cathode system and conservative charging profiles.
