Operating Instructions
Your UPSBatteryCenter replacement battery is designed to function seamlessly with your ONN 100008734 Medium Party Speaker. The speaker's internal charging system will manage the battery's charge and discharge cycles.
Charging:
- Always use the original charger provided with your ONN 100008734 speaker.

Maintenance
While the UPSBatteryCenter battery is maintenance-free, following these guidelines can help maximize its lifespan:
- Temperature: Store and operate the battery within recommended temperature ranges (typically 20°C to 25°C or 68°F to 77°F). Extreme temperatures can reduce battery life.
- Storage: If storing the speaker for an extended period, ensure the battery is fully charged. Recharge every 3-6 months to prevent deep discharge, which can permanently damage the battery.
- Cleaning: Keep battery terminals clean and free of corrosion. Use a dry cloth to wipe them if necessary.
- Recycling: When the battery reaches the end of its life, it must be recycled properly. Do not dispose of it in household waste. Contact your local recycling center for information on lead-acid battery disposal.
Troubleshooting
If you experience issues with your replacement battery, consider the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Speaker does not power on after battery replacement. | Incorrect terminal connection, loose connection, or battery not charged. | Verify positive and negative terminals are correctly connected. Ensure connections are secure. Connect the speaker to its charger and allow it to charge for several hours. |
| Battery life is shorter than expected. | High volume usage, extreme temperatures, or battery not fully charged. | Ensure the battery is fully charged before use. Operate the speaker in moderate temperatures. Reduce volume or features that consume more power. |
| Speaker not charging. | Faulty charger, loose charging port, or internal speaker issue. | Check the speaker's charging cable and adapter. Ensure the charging port is clean and secure. If the issue persists, the problem may lie with the speaker's internal charging circuit, not the battery. |
If troubleshooting steps do not resolve the issue, please contact UPS Battery Center customer support.
