AAAA Ni-MH Batteries

With a compact design and high energy density, this battery offers a single-cell capacity of 300 mAh—80% higher than traditional AAAA alkaline batteries. Optimized for micro-devices such as digital styluses, miniature medical equipment, and precision sensors, it extends runtime to 3–6 months, reducing replacement frequency. Customization options (e.g., size, capacity, protection circuits, cable length) are available to meet specific client needs. Our R&D team collaborates closely with customers to deliver optimal power solutions.

Additional features include:

• High capacity

• Low self-discharge

• No memory effect

• Extended cycle life

• Rapid charging capability

• Stable voltage output

• Superior safety performance

• Low short-circuit risk

• Wide operating temperature range

• Compatibility with multiple devices

• Eco-friendly and pollution-free

• Multiple certifications (UL/CE/Battery Directive Certification IEC 62133)

Widely used in security trackers, laser pointers, electronic signature devices, industrial IoT, consumer electronics, and other fields.
