ups不間斷電源維修方法四：

查機內(nèi)低壓保險絲正常，電瓶兩端不足5v的電壓，用新電瓶替換，將電源插頭插入市電，開機后立刻正常，在帶電情況下(注意)將新電瓶拔下并將原機電瓶接上，充電10小時左右，該機正常，證明原電瓶并未損壞，而是因長期擱置不用，自然放電造成的假性損壞。

UPS maintenance method 4:

Check that the low-voltage fuse in the machine is normal, and there is only a voltage of less than 5V at both ends of the battery. Replace it with a new battery. Insert the power plug into the mains power, and it will be normal immediately after starting the machine. When it is charged (pay attention to safety), unplug the new battery and connect the original battery, and charge it for about 10 hours. Everything of the machine is normal, which proves that the original battery is not damaged, but the false damage caused by natural discharge due to long-term use.
