5. Storage and Maintenance 

Operation  

The UPS system contains no user-serviceable parts. If the battery service life (3~5 years at 
25°C ambient temperature) has been exceeded, the batteries must be replaced. In this case, 
please contact your dealer.  

 
 

 
 

Storage  

Before storing, charge the UPS 5 hours. Store the UPS covered and upright in a cool, dry 
location. During storage, recharge the battery in accordance with the following table: 

Storage Temperature 

Recharge Frequency 

Charging Duration 

-25°C - 40°C 

Every 3 months 

1-2 hours 

40°C - 45°C 

Every 2 months 

1-2 hours 

 

 

 

 

Be sure to deliver the spent battery to a recycling facility or ship it to your 

dealer in the replacement battery packing material.
