Voltcraft CR2450 gombíková batéria 3 V 580 mAh lítium batéria balenie 40 ks VC-16865930

For high-drain devices that demand stable voltage over long periods, the Voltcraft CR2450 lithium button cell delivers dependable 3 V power in a compact 24.5 x 5.0 mm form factor. This bulk pack of 40 cells is ideal for professionals, technicians, and households that go through coin cells regularly—think car remotes, medical monitors, fitness trackers, and precision instruments. Unlike alkaline button cells that sag under load, the lithium manganese dioxide chemistry maintains a flat discharge curve and a 10-year shelf life, so spares stay ready when you need them.

Highlights

• Nominal 3 V output with 580 mAh capacity for consistent performance
• Lithium manganese dioxide (LiMnO2) chemistry for low self-discharge and long storage
• Mercury-free, lead-free, and cadmium-free for safer disposal
• Wide operating temperature range from -20 °C to +70 °C
• Bulk pack of 40 cells—cost-effective for multi-device use
• Flat top terminals ensure reliable contact in standard CR2450 holders

In daily use

Each CR2450 cell measures 24.5 mm in diameter and 5.0 mm in height, matching the IEC standard for this size. The flat top design works with most battery compartments, and the 1.74 Wh energy content supports both continuous low-current devices and occasional high-pulse loads like key fob transmission. With a shelf life of up to 10 years, you can keep a pack in a drawer or service kit without worrying about premature failure. The bulk packaging reduces individual wrapping waste while keeping cells protected during transport.
