01

ULTRA-COMPACT PROFILE, MINIMIZED FOOTPRINT (14250 FORM FACTOR)

Specifically engineered in the 14mm x 25mm cylindrical 14250 size (similar to a 1/2 AA battery), this cell is the ultimate choice for high-density electronic designs where standard AA or AAA batteries are too bulky. It enables engineers and designers to shrink the overall size of devices without sacrificing essential power features.

02

IDEAL FOR NICHE AND INTELLIGENT APPLICATIONS

This battery is perfectly suited for devices requiring a compact power source with consistent voltage and low current draw. Typical applications include smart sensors, medical instruments (like a digital thermometer), IoT devices, security systems, high-end EDC (Every Day Carry) flashlights, and intricate remote controls, where larger batteries won’t fit.

03

RELIABLE, STABLE 3.7V POWER PLATFORM

While small in capacity (250mAh), the battery utilizes advanced Lithium-Ion chemistry to provide a stable and consistent 3.7V nominal output. This is a critical advantage for precision instruments and sensitive micro-electronics, ensuring they receive steady power with minimal voltage fluctuation.

Technical insight

Product and application details

alarm system

Its compact 8.5g weight allows installation in tight alarm panels without adding unnecessary bulk to the housing design.

gas meter

The 3.7V nominal voltage provides stable energy for periodic gas readings while maintaining a low self-discharge profile.

IoT device

With a 250mAh capacity, it sustains low-power IoT sensors during long-term deployments without frequent battery replacements.

medical device

The low 120mΩ internal impedance ensures consistent current delivery to sensitive medical monitoring equipment during operation.

RFID tag

Its small 14x25mm form factor fits discreetly within RFID tags while providing sufficient energy for brief signal bursts.

smart meter

The ability to handle 3C discharge currents supports sudden power demands from smart meters during data transmission spikes.

smoke detector

A minimum capacity of 240mAh guarantees reliable operation for smoke detectors over extended periods between battery changes.

wireless sensor

The lightweight 8.5g construction reduces overall device mass, which is critical for portable wireless sensor network nodes.
