Mail to Manager That Ups Batteries Are Down
Mr. Adnan Malik I am sending this mail to you so that I can tell you about the ups batteries problem. Yesterday I was in office at night and at almost 11 o’clock the electricity gone all of a sudden, ups on at the moment for about 15 minutes and after that they stopped working, and when I checked their condition I came to know that batteries need service.
Please check them and inform me. Do this soon as workers are facing problems while doing work.
Letter for Maintenance of UPS Batteries
To: OSAKA Repair Dept., Tokyo, Japan
I am writing in regards to the UPS Batteries I had purchased 3 years ago. The batteries used to perform very well.
However as of late, the batteries are unable to properly hold a charge. During power outages the ceiling fan has extremely low speeds and the lights around the house tend to flicker.
I request that a serviceman come as soon as possible to repair and/or replace the batteries.
