Car Remote & Device Battery Guide 2025: Renata & Panasonic Button Cells in Kenya

When your car remote stops working, the first culprit is almost always the battery. That tiny coin-shaped cell inside your key fob or smart card is one of the most important components—without it, you’re locked out of your own car. The same is true for watches, calculators, medical devices, and countless other electronics.

In 2025, two brands stand out as the most trusted button cell manufacturers worldwide: Renata (from Switzerland, part of the Swatch Group) and Panasonic (Japan’s global tech leader). Both offer long-lasting, reliable coin cell batteries that are widely used in Kenya.

In this guide, we’ll explore:

  • The role of button cell batteries in everyday devices

  • A deep dive into Renata and Panasonic battery models (2032, 2025, 1632, 1620, 1616, 2450)

  • The cars and electronics that rely on them

  • How to choose the right battery replacement

  • Where to buy genuine button cell batteries in Kenya (Suncom Ltd)

Let’s begin.

🔋 Why Button Cell Batteries Are So Important

Button cells—also known as coin cell batteries—are small, round, and flat batteries that power compact devices requiring low but steady energy consumption. Unlike AA or AAA batteries, they are designed to:

  • Deliver a consistent 3V output for sensitive electronics

  • Last years before replacement (depending on usage)

  • Fit into tiny devices like car remotes and watches

Common devices that use button cell batteries include:

  • Car key remotes and smart cards

  • Wristwatches, smartwatches, and fitness trackers

  • Medical devices such as glucometers, digital thermometers, hearing aids

  • Household electronics like calculators, digital scales, cameras, toys, garage door openers, and IoT devices

In Kenya, the car remote is the most common reason people shop for button cells. If you drive a Toyota, Nissan, Honda, Subaru, Kia, Hyundai, Volkswagen, or BMW, chances are your key fob runs on a Renata or Panasonic battery.
