Understand battery characteristics: Before you start switching, be sure to understand the characteristics and operating requirements of lithium batteries. Compared with lead-acid batteries, lithium batteries have a higher energy density and faster charging speed. However, they are also more sensitive and require special charge and discharge management.

Select the right lithium battery: Select the lithium battery model that matches the UPS system. Ensure that the selected lithium battery has the appropriate capacity and voltage to meet the needs of the UPS system.

Turn off the UPS system: Make sure you turn off the UPS system before you start switching. This will ensure that no damage is caused to the system or equipment during operation.

Remove lead-acid batteries: Carefully remove lead-acid batteries from the UPS. Please note that lead-acid batteries may contain harmful substances, so please dispose of them properly according to local environmental requirements.

Install the lithium battery: Follow the guide provided by the UPS manufacturer to properly install the lithium battery. Make sure the battery is properly connected and follow any safety precautions.

Adjusting UPS Settings: You may need to adjust UPS Settings based on the characteristics of the lithium ion battery. This may include adjustment of charging and discharging current, voltage and other parameters. The corresponding Settings are based on the documentation of the UPS manufacturer and the lithium battery manufacturer.

Test the UPS system: After the replacement is completed, the UPS system is tested to ensure that it is working properly. This includes checking whether the voltage, current, capacity and other aspects of the system are normal, and whether the match with the lithium battery parameters is appropriate.

Maintenance and monitoring: Compared with lead-acid batteries, lithium batteries require more frequent maintenance and monitoring. Check the voltage, current and temperature of the lithium battery regularly to ensure that it is working properly. In addition, follow the UPS manufacturer's and lithium battery manufacturer's guidelines for regular maintenance and maintenance.
