1. Storing in a dry environment can delay discharge and extend the actual usable time.
2. Reverse installation is prohibited to avoid damage to the device circuit.
3. Apply appropriate pressure to the spring contacts. Too loose will cause high-frequency vibration disconnection.
4. Do not submerge the battery in water.
5. Before unpacking, touch grounded metal to release static electricity to avoid sparks igniting electrolyte vapor.

9V carbon batteries power critical devices: smoke detectors, multimeters, guitar pedals, radio transceivers, and vintage electronics. Their stable voltage suits precision instruments.
