Advantages of rechargeable lithium manganese dioxide coin cells

Rechargeable coin cells offer numerous advantages that make them an attractive choice for many applications where permanent cell replacement is undesirable, too costly, or impractical. Their compact size makes them ideal for space-constrained applications, while their wide temperature range ensures reliable operation at both high and low temperatures. With a low self-discharge rate of less than 2% per year, they are also extremely efficient.

One outstanding advantage is their environmental friendliness. Rechargeable coin cells reduce waste as they can be reused many times, unlike disposable batteries, so-called primary batteries, which have to be disposed of after a single use. This leads to a significant reduction in environmental impact and costs for the user. In addition, they have high cycle stability and constant performance over their entire service life, making them especially suitable when a reliable and long-lasting energy source is required. These cells do not need to be replaced regularly, which simplifies maintenance and reduces the risk of leaking or corroding batteries.

Areas of Application

Rechargeable coin cells from Jauch can be used in many different areas. They are often designed as a back-up battery to keep the date and time of devices running in the background:

• Tracking: For tracking objects or animals, as they provide a reliable source of energy for GPS trackers.
• Radio and RFID: For wireless communication systems and RFID tags used in logistics and inventory monitoring.
• Data Backup: For cell phones and other electronic devices to protect data during power outages.
• Medical Technology: For portable monitoring devices, medical sensors and dosing systems that require a constant and reliable energy source.
• Automotive: For various sensors and control units that are integrated into vehicles.
• Smart Metering: For intelligent meters that require a continuous energy supply.
• Security technology: For access control and other security applications that rely on a stable power source.

With the new rechargeable lithium manganese dioxide coin cells, Jauch offers a sustainable and powerful solution for developments that are designed for longevity and require a high degree of safety and reliability.
