4. Operating Instructions
The SPANN CS-ALT323CL battery is a Ni-MH (Nickel-Metal Hydride) type, known for its reliability and performance.
- Initial Charging: For optimal performance, fully charge the battery for at least 12-16 hours before its first use. This helps to condition the battery.
- Regular Charging: Place the handset on its charging base when not in use. The battery is designed with over-charge protection, preventing damage from continuous charging.

5. Maintenance
Proper maintenance ensures the longevity and performance of your battery.

- Cleaning: Keep the battery contacts clean. Use a dry, soft cloth to wipe away any dust or debris.
- Disposal: Do not dispose of the battery in household waste. Ni-MH batteries contain recyclable materials. Please dispose of it responsibly at a designated battery recycling facility. Consult local regulations for proper disposal methods.
6. Troubleshooting
If you experience issues with your battery, consider the following common troubleshooting steps:
- Battery Not Charging:
- Ensure the handset is correctly seated on the charging base.
- Verify that the charging base is powered on and connected to a working outlet.
- Check the battery connector for proper connection and ensure it is not loose.
- Clean the charging contacts on both the handset and the base.
- Short Battery Life:
- Ensure the battery has completed its initial full charge cycle (12-16 hours).
- Over time, all rechargeable batteries experience a natural decrease in capacity. If the battery is very old, replacement may be necessary.
- Ensure the phone is not constantly searching for a signal in an area with poor reception, which can drain the battery faster.
- Phone Not Powering On:
- Confirm the battery is correctly installed and fully charged.
- If the issue persists, try placing the handset on the charging base for a few minutes to see if it powers on.
