I fixed mine by wiring in an old 12vdc. 500ma wall wart. This powers the UPS circuit while at the same time it keeps the battery topped off just like the internal circuit is supposed to... but no longer does.

May be a number of problems fuse in mains plug fuse in UPS unit may be the battery is 'floating'

Most of the times, if not the battery is dead, is one of the electronic components inside. I bet that most of the times is one of the capacitors, but is not easy to know which one.

My problem is when electric supply is down then our power is connected to the ups through the MCB.why mcb will be off.

May be because of the charger fuse or the charger device inside the ups
