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).
NOTE:
The batteries in the UPS are rated for a 3–5 year service life. The length of service life varies, depending
on the frequency of usage and ambient temperature. Batteries used beyond expected service life will often
have severely reduced runtimes. Replace batteries at least every 5 years to keep units running at peak
efficiency.
