VARTA Professional Electronics CR2025 - High Performance 3V Lithium Coin Cell Battery

VARTA Professional Electronics CR2025 - High Performance 3V Lithium Coin Cell Battery

The VARTA Professional Electronics CR2025 is a premium power solution designed specifically for modern electronic devices requiring a compact yet powerful power supply. Unlike generic coin cell batteries, this lithium battery has been developed under VARTA's rigorous German quality standards, guaranteeing not only a long lifespan but also exceptional voltage stability throughout its service life. It is the preferred choice for equipment that demands precise and reliable power pulses.

Part of the Professional Electronics range, this battery stands out for its advanced Lithium-Manganese Dioxide (Li/MnO2) chemistry. This technology allows for a significantly higher energy density than conventional alkaline batteries, offering a nominal voltage of 3 volts in an extremely lightweight and flat format. Its design is optimized to withstand harsh environmental conditions, ensuring your critical devices function correctly in both cold winters and hot summers, thanks to its wide operating temperature range.

In addition to their technical performance, VARTA has prioritized safety and durability in storage. With an extremely low self-discharge rate (less than 1% per year at room temperature), these batteries can be stored for up to 10 years without losing their effectiveness, making them an ideal backup to always have on hand at home or in the office.

Main features

• Premium Lithium Technology: Offers high energy density and a stable 3V voltage, essential for precision electronics.
• Extreme Temperature Performance: Designed to operate effectively in a thermal range from -20°C to +70°C.
• Long Storage Life: Retains its charge for up to 10 years, ensuring immediate availability when most needed.
• Certified Safety: Leak-proof construction and packaging designed for child safety.
• Standard Dimensions: CR2025 format, 20 mm in diameter and 2.5 mm thick, universally compatible with devices that require this nomenclature.

Product benefits

Choosing the VARTA CR2025 Professional Electronics provides peace of mind, knowing your devices won't fail you in critical moments. For smart car key users, this means avoiding the frustration of a malfunctioning remote. In the healthcare sector, it ensures accurate readings on thermometers and glucometers.

Furthermore, its longevity reduces the frequency of replacements, which translates into long-term cost savings and less waste. Its reliability makes it perfect for both everyday home use and professional applications where battery failure is unacceptable.

Use cases

• Automotive: Car remote controls, proximity keys and alarm systems.
• Health and Wellness: Glucometers, digital thermometers, heart rate monitors and bathroom scales.
• Home and Office: Garage door openers, scientific calculators, LED candles, and lighting system remote controls.
• Computing: Backup batteries for motherboards (BIOS/CMOS) in computers and laptops.
• Leisure: Digital watches, pedometers and active 3D glasses.

Frequently Asked Questions

• Can I use a CR2025 instead of a CR2032?
  Although both batteries operate at 3 volts and have the same diameter (20 mm), they are not interchangeable. The CR2025 is 2.5 mm thick, while the CR2032 is 3.2 mm thick. Using a CR2025 in a CR2032 socket could result in poor contact due to its thinness.
• Is this battery rechargeable?
  No, the VARTA CR2025 is a single-use lithium primary battery. Attempting to recharge it can be dangerous and may damage the charger or the battery.
• How should I dispose of this battery?
  Because it contains lithium, it should not be disposed of with household waste. It must be taken to designated battery collection points (recycling centers) for proper recycling.
