5. Operating Instructions

Once installed and fully charged, the PEGATRON PB018A2 battery operates automatically:

Normal Operation: When your modem is connected to AC power, the battery remains in standby mode, continuously charging to maintain full capacity.
Power Outage: In the event of a power outage, the battery will automatically provide power to your cable modem's phone service functionality. This allows you to continue making and receiving calls through your landline phone service for approximately 8 hours, depending on usage and modem model.
Power Restoration: When AC power is restored, the modem will switch back to wall power, and the battery will automatically begin recharging.

6. Maintenance

Battery Life: The typical lifespan of a Lithium-Ion battery is several years. However, performance may degrade over time.
Replacement: If you notice a significant reduction in backup time or if the battery indicator on your modem suggests a fault, it may be time to replace the battery.
Storage: If storing the battery for an extended period, ensure it is partially charged (around 50%) and stored in a cool, dry place within the recommended temperature range (-20°C to 60°C).
Disposal: Dispose of old batteries responsibly according to local regulations for Lithium-Ion batteries. Do not dispose of in household waste.
