My sukam 800VA inverter is not being charging even if there is power, And it is continuous beeping in backup mode. So what I should do now.

Can your charge the batteries at a gas station, then plug in to see if the internal charger is blown? Or just take out the batteries and disconnect them, Then, hook up a volt meter to the batteries. If <5 volts , replace and try again. Mine wouldnt work and when I put in a spare, worked fine. One of the 12V batteries was D E A D. As to not charging fault, with a known good batte[ry] [ries] in, measure the voltage. SHould be about 13 volts or more after a while. If say 12V, you may have a dud transformer, fuse or rectifier (diode). I had a blown fuse and and open transformer after hurricane Sandy. Replaced botha nd it works fine now.

Sukam 800VA not charging my battery

Check the charging voltage if you know how to use a multimeter .
if it is 13 volts then it is ok.please tell me how old is your UPS and battery.if the battery is 2-3 years then it may need replacement.
after checking the charging voltage charge the battery or some 6-8 hours promptly maintain charging .

Replaced conext ups cnb325 battery but power indicator light does not come on.

There is a solder problem on some units. Remove the battery and the 4 screws, tilt the lower panel away, and let the circuit board drop out onto the workbench. WATCH FOR THE TRANSFORMER, it is not fastened. Inspect for a loose solder connection, and if you find it, re-flow the solder. Re-assemble and plug into the AC current to charge the battery.

Ups starts beeping

Is there any indicator lights ON showing the fault condition?
This could indicate that the battery has a low charge. Even if you switch off the mains supply and it switches over to the battery, the UPS may shut down after a short time as the battery power (charge) runs out.
If the battery is more than 3 years old then it may be due for replacement.

Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. There maybe one battery in a set of batteries that is faulty and causes the whole battery system to fail and indicate a battery fault.
The other possibility is the charging circuit may be faulty.
