Sounds like it is not regulating the voltage and current charging the batteries. Consult a service manual to look for a repair method.

It either means the ground wire in extension cord is not there or is open. It could also mean that the outlet wasn't wired with a ground back to the panel.

You can check the battery fuse or the charging fuse. If it's more then that it's going to be a very costly fix.

You need special software, which costs money ...

When you are sure you have a good battery and the voltage regulator works fine, I should think there is something eating power during the time you switched off. Years and years ago sometime a car radio was connected wrong and would not switch off when the contact was off. Now you should disconnect the battery when you switched of and use a huge ampere meter DC to see if and if so what current is "leaking" away If there is no current, then check the barrery and the voltage regulator.

A Bosch 70745 is a cordless tool; the battery recharges with a power pack, or a plug in charging station. This is not a UPS Battery Backup system.

Does the fan come with 2 or 3 wire.

There may be a reason. Too much current draw.
I would recommend to get a better brand UPS.

Okay
