BATTERY FACTS 

 
The  battery  is  the  only  periodically  serviceable  parts  in  the  UPS.  An 
expected  life  is  approx.  3

5  years.  However,  frequent  long  discharges  or 

ambient temperatures above 80

°

F/26

°

C

 will shorten battery life. Therefore, it 

is  recommended  to  replace  the  batteries  every  3  years  after  initiating  the 
unit. 
 
Recharge batteries every 3 months if it is not in use because it may cause 
batteries over-drain. 
 

WARNING 

Only  a  qualified technician  should  replace  the  battery.  Batteries  have 
high  short-circuit  current  capacity;  mistakes  in  connecting  or 
disconnecting can cause connections to arc or weld and could cause 
severe burns. 
 

STORAGE 

The UPS should only be stored if the battery is fully charged. Avoid storage 
temperatures  above  80

°

F/26

°

C

  as  battery  life  is  significantly  shortened. 

Every  90  days  remove  the  unit from  storage  and  plug  it  in for  24  hours  to 
recharge the batteries. Batteries may be damaged if left in storage and not 
recharged every 90 days. 
 

IMPORTANT NOTICE 

Please use same type and same rating of batteries for replacement. 

Do not replace it with the battery that exceeds specified rating.

2. Normal Operation 

There are two main loops when AC Utility normal the AC output loop and the 

battery  charging  loop. The  AC  output gets  power from  AC  utility  input  and 

pass through AVR to support power to load. In the same time, the AC utility 

input  is  converted  by  AC/DC  CHA  and  support  charging  power  to  charge 

batteries.
