How to use
Before installation, confirm the required cell size in your device and ensure polarity alignment when inserting the battery. Use a non-conductive tool or finger to place the cell into the battery compartment with the positive side facing the correct terminal as indicated by the device. Avoid forcing the cell into place; if it does not fit easily, verify the compartment is compatible with this button cell size. Dispose of used batteries following local regulations for battery recycling.
Usage recommendations
Store unused batteries in a cool, dry place away from direct sunlight and metal objects to prevent short circuits. Do not recharge, disassemble, puncture or expose the cell to fire or high temperatures. Replace the battery promptly when device operation becomes unreliable or when low-battery indicators appear.
