COIN CELLS

YOK Energy Lithium Cylindrical Coin Cells batteries can be integrated across a wide range of healthcare, consumer, and domestic applications, which require a high energy density solution in a very small package.

These small form cells are used successfully in a range of devices, such as the latest generation hearing aids, earbuds, and IoT sensors, whether for temperature, proximity, pressure, infrared, smoke, motion, or any other type of sensor required by increasingly intelligent technology.

Designed and manufactured to high YOK standards

They may be small, but these rechargeable coin cell batteries still pack a punch in terms of safety, power, durability, and longevity.

Manufactured on YOK’s fully automated production lines, the batteries guarantee the highest standards in terms of consistency in quality and performance. The adherence to quality, detail, and performance is maintained on every bespoke project YOK Energy works on, creating rechargeable coin cell battery solutions that can respond to specific requirements, maintaining the integrity and optimising performance.

Off-the-shelf or bespoke
