How to replace the battery of a UPS.

A UPS battery is subject to the test, the ups being constantly in charge, the battery continues to cycles of charge and discharge. A UPS battery autonomy varies depending on the amperage it. More the amperage of the battery is great over the inverter will remain in operation during a power failure. Unfortunately the amperage of a battery being proportional to its size, it is impossible to have too large gaps.

Extraction and battery connection

1 disconnect the appliance sector and computer, all manipulations must be turned off.

2. remove the hood of the ups, by unscrewing the screws on the bottom, or by moving the door.

3 remove the capo in order to extract the battery. (for this example, the used battery is a HR1234W )
4. disconnect the defective battery. The faston lugs can be difficult to unclip, do not hesitate to pull hard.

5. install the new battery making sure to respect the polarity red + black-

6. close the appliance. 
7 reconnect the ups to the mains to charge the new battery completely.
