Disposal of the UPS and batteries should be carried out by a certified disposal
The typical battery lifecycle is 3 to 5 years at an ambient temperature of 25 C, but is also dependent on the frequency and duration of utility failures.
The BATTERY TEST (see 4.8.2 - Battery Test) should be run periodically (6 to 12 months) to ascertain the general condition of the batteries and ensure maximum run time.
5.2Storage
For extended storage at ambient temperatures cooler than 25°C (77°F), the batteries should be charged for 24 hours once every six months.
Connect the UPS to a utility outlet socket having a ground (earth) connection and ensure the miniature circuit breaker is closed. If charging batteries with fixed utility connections, make connections in accordance with 3.0 - Installation.
After 24 hours, disconnect the UPS from the utility supply.
5.3Cleaning
The UPS may be cleaned by wiping it off with a dry cloth. Do not use liquids or solvents.
