With the increasing popularity of smart devices, smart anti-lost devices have become an indispensable tool in the lives of many people. Whether it is tracking keys, wallets, luggage, or the location of pets, smart anti-lost devices can help us quickly locate and avoid loss. However, the performance and reliability of these small devices largely depend on their core power source - button batteries. CR2032 and CR2025 button batteries have become the preferred power source for smart anti-lost device positioning systems due to their high capacity, long storage time, low self-discharge rate and long life.
