UPS not charging

Take the battery out and check the pins on the connectors and make sure they are not bent or damaged.

Now what is the condition of the phone ? If the phone has still problem, uninstall the previous file you have installed and re-install this one3110c file.Select the product code 0544311 or 0556977.This two files can use universal.Use fully charge battery or insert charger when message prompt.I hope there will be no error.Thanks good luck.

Hello, it is possible that the battery inside the UPS needs to be replaced as it may no longer be able to hold a charge. If you can test the battery for voltage, and it is less than what it should be, replace the battery. If the battery is what it should be, then your UPS has malfunctioned, and there is not much you can do to fix it.

Thanks for using FixYa!

Is this unit new or used? Either way, the first thing to check is if the battery is plugged in. UPS units are shipped with one of the battery leads disconnected for safety purposes. Please remove the front plastic bezel and verify the battery is plugged in. If it is new, and you followed the instructions correctly, you could have a bad battery or charging unit in the UPS. Please contact technical support for the manufacturer.

If you have a used UPS, disconnect the battery connections and use a multimeter to check for existing voltage on the battery. If it is completely dead after a charge cycle, it is quite possible the battery is bad and needs replacement.

Friend have you plug and switch the ups properly, If so then check that you have also plug your computer pin properly into a ups. If this is also right then there might been problem in a UPS charging or in ups. It might also be a system fault. Just check out the system fault by applying the direct connection to the socket. If this solve your problem then check out all the procedure of ups to work and if this does not solve problem repair ups or charge it properly. If the ups is also not charged then it also make a problem to start for sometime.

Normal for a battery that is starting to show its age. Save for a replacement in the near future.

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. If one battery is faulty in a set of batteries it will causes the whole battery system to fail and indicate a battery fault.
A faulty charging circuit will not charge the batteries and will also cause a fault condition.

These lower powered and cheaper KVA type UPS are switch over types, when the mains supply fail, the UPS switches over to the inverter in milli-seconds which then supplies mains power but the power waveform is a pseudo sine wave (ie not a true sinewave. A faulty inverter circuit won’t deliver power when the mains supply fails.

check your fuses some fuse blown.

It does not look good for this unit.
Time to upgrade, go bigger. Maybe this unit is too small for you system. Most likely a 1000VA will solve your problem.
