When the electricity is used to put the battery in the battery with the electricity out of the USP automatically turned off by the open up with a one will put the electricity out of a power outage UPS can only work two minutes ago almost 10 minutes I used UPS with a Computer host and a liquid crystal display
First put the electric finished, and no load charge.
You put the battery with a bad! do you know? UPS automatic shut down is to protect the battery, do not let the battery over discharge! If you use this, the battery is damaged due to excessive discharge!
There is a way do not know can not, you can try to remove the battery out, with an external charger, a separate charge to each battery, filled with about 13.6 ~ 14V it, you find a load to it discharge, probably put 10 ~ 10.5V! Put it in after charging it, in the discharge, repeated several times! If you are lucky, the battery can be restored about 80%! If luck is not good! Then you honestly change the battery!
Your battery is over discharge, but also a power off it, but 2 minutes enough for you to shut down the security, so continue to use no
Change the battery it, the life of this thing is basically 18 months, do not think it is too god, and if the replacement is still so recommended to let them check
