Although the points are not enough but still give a good heart to give an answer, please!
Do not take the load charge 6 hours of electricity, press the switch to turn off the power, if the alarm can be used, if the power is turned off after the UPS can not be used
To the UPS charge ten hours later, the computer power plug in the UPS backup socket, the computer boot, and then unplug the UPS plug to see the computer can work a few minutes, such as working hours in more than 2 minutes are considered more normal.
As long as the battery is not dry, it should not be a problem. As a lot of UPS batteries are maintenance-free, easy to dry, you can first charge a good test, if you feel the backup power supply time is insufficient, or very short, you can replace the corresponding battery.
