UPS and Battery Care

For the best preventive maintenance, keep the area around the UPS clean and dust-free. If the atmosphere is very dusty, clean the outside of the system with a vacuum cleaner.

For full battery life, keep the UPS at an ambient temperature of 25°C (77°F).

Storing the UPS and Batteries

If you store the UPS for a long period, recharge the battery every six months by plugging the UPS into a power outlet. The UPS charges to 90% in approximately 12 hours. However, it is recommended that the UPS charge for 24 hours after long storage.
