This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask the answer of. Earn your diploma.
No, a ups backup battery cannot be purchased at the UPS store. A ups backup battery can, however, be purchased at any electronics store, or at a big-box store such as Walmart.
Battery Bank Installation: In Telecom BTS site 48 volt DC battery bank installed. there are 24 cells in each Battery Bank each is having the 2 volt DC. These battery bank are installed on stand and grouted in the shelter properly. These battery bank have certain distance from the SMPS and we should try to keep O/P of each terminal is in opposite direction of SMPS. Grounding of Battery bank is done with the IGB by the 35 mm square grounding cable & connected to EGB (Internal Grounding Bar).

You would have to know the voltages of the battery and the UPS to know for sure. For example if the UPS' output is 120 volts, then it is capable of 5 amps of output. If the battery is also 120 volts, then it would take the UPS 29 hours to fully charge the battery. However if the battery was rated at 220 volts, then the UPS would never completely charge the battery. The source of the charging voltage must exceed the battery's voltage in order to fully charge it.
The battery is defective and has a dead cell. Replace the battery.
In an uninterrupted power supply there has to be a source of power when the electrical utility is not there. The only supply that is available is a battery that is in or connected to the UPS.

For the backup time for 4 fans. First we required battery AH (battery amper) and battery volts & and and ups ratings. then we calculate back time .
