• Customised assemblies and tabbed versions available

Lithium polymer batteries for medical equipment

Renata’s rechargeable lithium polymer batteries are a comprehensive series of 3.7-V lithium-ion polymer (Li-polymer) rechargeable batteries, providing a compact, lightweight and reliable power source for portable devices.

The batteries offer a proven pouch pack technology while optionally incorporating an internal safety circuit that provides fail-safe protection against overcharging, overload and over-discharge.

Pouch pack batteries are up to 20% lighter than conventional cylindrical cell batteries, and the compact packaging enables design engineers to utilise thinner batteries for original equipment manufacturer (OEM) applications.

On top of this, most of Renata’s standard lithium polymer batteries are certified according to the International Electrotechnical Commission (IEC62133) safety standard, mandatory for high-quality industrial and medical applications.

Thin film batteries for medical sensors

With 0.4mm of thickness, the bendable Renata thin film battery is ideal in creating flawlessly fitted and wearable electronic devices.

Renata thin film batteries are available for use in a wide range of industrial, medical and consumer applications such as smart cards, smart textiles, price tags, smart packaging labels, smart wristbands and sensors.

Customisable lithium coin cells

With its low self-discharge rate, wide temperature range, and high pulse load performance, Renata’s lithium batteries meet the highest levels of quality and reliability. Standard tabbed versions, as well as customised assemblies and custom tab shapes, are available to match individual application requirements.

In addition to the wide spectrum of memory backup power sources, Renata’s lithium batteries are available for applications in the telecommunications, computer and medical industries, along with a variety of portable devices.

User-friendly battery holders

Renata battery holders are designed for easy and fast replacement, as well as safe retention and reliable connection of coin cells.

Battery holders are suitable for reflow-soldering and automatic pick-and-place mounting. A variety of different versions enables for vertical and horizontal battery alignment in a surface-mounting or through-hole assembly.
