- Identify the battery compartment on your electronic device. This is often secured by a small screw or latch.
- Carefully open the battery compartment. If a tool is required (e.g., a small screwdriver), use the appropriate one.
- Remove any old batteries, if present. Dispose of them according to local regulations.
- Observe the polarity markings (+ and -) inside the battery compartment.
- Insert the new AG13/LR44 battery, ensuring the positive (+) side aligns with the positive terminal in the compartment and the negative (-) side aligns with the negative terminal.

This side typically connects to the negative terminal within the device's battery compartment.
4. Operating Instructions
Once the batteries are correctly installed, your device should function as intended. These batteries provide a stable 1.5V output suitable for low-power electronic devices.
- Ensure the device is turned off before installing or replacing batteries.
- After installation, turn on your device to confirm proper operation.
- If the device does not power on, re-check battery orientation and ensure the batteries are new and fully charged.
5. Maintenance and Storage
Proper maintenance and storage can extend the life and safety of your batteries:
- Store unused batteries in their original packaging in a cool, dry place at room temperature.
- Avoid storing batteries in direct sunlight or in areas with extreme temperatures (hot or cold).
- Do not store batteries loose in a pocket or purse with metal objects like coins or keys, as this can cause a short circuit.
- If a device will not be used for an extended period, remove the batteries to prevent potential leakage and damage.
- Dispose of used batteries responsibly according to local regulations. Many communities have battery recycling programs.
