More Hours. Less Cost.
Optimized for low-drain applications. Engineered to deliver maximum energy efficiency where devices draw small, steady amounts of power over extended periods.
DUKECORE™ E is designed for devices with low continuous drain — applications where the battery provides small, steady current over months or even years. The focus is on energy efficiency: delivering the most usable hours per unit of cost.
E is not a "low-end" product. E represents efficiency optimization for specific low-power use cases.
