Type-C rechargeable AA, AAA and 9V cells replace throwaway primaries with reusable lithium power that charges straight from a USB-C cable.

Disposable alkaline batteries end up in household waste after a few hours of use. Type-C rechargeable AA, AAA and 9V cells offer a practical alternative: the same familiar form factors, but with a built-in lithium cell and a USB-C port that lets users recharge them hundreds of times. SUNHE ENERGY develops this product line for everyday household and hobby devices.

Replacing Disposable Cells with Rechargeable Ones

Remote controls, wireless mice, keyboards, flashlights, toys, meters and smoke detectors still run on AA, AAA or 9V cells. By switching to a rechargeable version of the same size, users keep the devices they own while cutting the number of batteries they throw away. Each reusable pack reduces waste over its lifetime and saves the repeated cost of buying primaries.

Type-C Convenience

The defining feature of these cells is the USB-C port built directly into the battery. No separate charger, no proprietary dock: the user plugs a standard USB-C cable into the cell itself. We design the internal protection and charging electronics so that the cell charges safely from common USB power sources and delivers a stable output to the host device.

Built for Repeated Use

A rechargeable cell earns its place only if it lasts. Our Type-C rechargeable line is engineered for repeated charge and discharge cycles, with protected circuitry against overcharge and short circuit. It is a practical, greener choice for consumers and businesses tired of throwing away batteries, and a natural extension of SUNHE ENERGY's work in reusable lithium power.
