Setup
Identifying Your Battery
Ensure you have the correct battery type for your device. The Energizer 364 / 363 SR621SW is a common silver oxide button cell battery. Always cross-reference the model number on your old battery or device manual with the new battery.
Preparing for Installation
Before handling the battery, ensure your hands are clean and dry. It is recommended to use non-conductive tweezers to avoid touching the battery's surface directly, as oils from your skin can affect performance and lifespan. Work in a well-lit area to prevent misplacement of small components.
