Ups not charging the battery
My ups is not charging. The problem is not of battery, what else should I check in the circuit.
Is this a good question?

These things usually have two batteries and usually one will fail before the other. Look at the diagnostics lights on it and tell us what you see.

the green light is not stable. It comes on, and goes off immediately
This is not a solution, and not helpful.

I have the same issue. CyberPower replaced my battery because I thought that was initially the problem. The replacement battery came charged, but ran down and isn't charging. It seems like the unit itself isn't charging the batteries.

GS1500U 1. Bought 2 new batteries 2. The new batteries discharged to 0% 3. Reveived 2 more new batteries with 93% charge leaving the store 4. Hot home plugged it in to see if it would charge 5. It began to discharge from 93% to 84% 6. I let it run plugged into the wall with nothing plugged into it. 7. Awoke this morning to a 16% charge 8. That is a discharge from 93% to 16% in less than 24 hours with nothing plugged INTO the GS1500U. Any advice is appreciated to fix this.
Thank You
Did you find a fix for this as I am having that same problem?
@danielaleburgess have you chek the voltage battery ? let me show you how to chek
Yes, battery showing 50v. Checked the charging voltage and it was only 34v??
at power on position / standby dislodged the negativ/black cable and if the ups its dead you must replace the battery regulator Sir at ups ica usually use lm317 , what type ups with 50v battery ?

I have a similar problem with my CyberPower UPS (model CP1000PFCLCD). It seems the only time it will charge the battery is immediately after a selftest; it charges the battery to full after a selftest but then it ridiculously thinks the battery stays fully charged while the battery actually gradually loses its charge (which will eventually destroy the battery if it’s allowed to discharge too far). The reason I believe the UPS hasn’t been keeping the battery charged is that the selftest reduces the reported battery charge from 100% to about 65% in a few seconds, and then it takes hours of charging before the UPS software (CyberPower PowerPanel Personal v2.2.0) reports the battery is again at 100%.
So, for awhile it was possible to maintain a charge by periodically performing a UPS selftest. I’ve been doing a selftest about once per month.
However, recently the UPS developed a second problem that magnifies the first: During the selftest, the pc “loses communication” with the UPS (connected via usb port), the software doesn’t indicate the selftest has completed, and the UPS seems like it remains in battery mode… its internal fan doesn’t stop spinning, as if it isn’t cooling down and is continuing to drain the battery. To protect the battery from being drained so far that the battery is damaged, and to protect my pc from losing power and crashing, I respond by quickly shutting down the pc, then shut off and restart the UPS, and then restart the pc. After startup the UPS software reports the selftest was passed, but given the circumstances I don’t have confidence that that report is valid. The software also reports the battery is fully charged, which is implausible since I know from experience that it takes hours to reach full charge after a selftest. My hunch is that the battery is now never being charged and will eventually be permanently damaged.
I replaced the battery in the fall of 2019 because the original battery died. Perhaps the original battery would still be okay if the UPS had kept it charged.

It looks like we (and others) have the same problem with Cyberpower UPS supplies. I have been in touch with them in order to get some help or a schematic diagram but, even though they promptly replied, they were unable to help
I don't have mine connected to my computer but trying out some troubleshooting I come to the conclusion that the battery charging circuit or the battery detection circuit is not functioning. My unit works normally with a partially charged battery but soon turns off when the charge is below a low voltage limit ( it will not even turn on with the battery disconnected.) I measured the battery current and it is 150ma discharge when plugged in and turned on. It jumps high then quickly returns to 150ma discharge when unplugged. It provides power until the battery voltage goes below the LV limit. I'm considering connecting an external battery charger to it through a connector to keep the battery fully charged.
Any ideas?
Thanks
@LeRoy Osborn: The only idea I have is the obvious one: never again buy a CyberPower product.

I have the same problem and the same final idea.
Same here. Replaced battery Feb 2019 as I thought my old battery was shot. Turns out the unit doesn't charge the battery. At all. PowerPanel claims it's charging and shows a full battery after many hours, but run a single Self-Test and it's 0% battery instantly.
If the UPS is not charging the battery,They should check the battery connection,Integrity of the battery and Battery charger. Saheed Adeosun

My mom is having similar trouble with her APC XS 1000 unit, battery is actually 3/4 full when unit is unplugged from the wall and still provides power to computer. Checked circuit breaker on the unit and that of the power strip, all good. All unit vitals look fine aside from showing 0% battery life when plugged in and hearing constant yet intermittent chirps from the APC unit.
I’m personally thinking this is a self test issue where the unit does not detect a successful switch over to battery usage before it switches back to normal mode. Therefore the battery is fine, but there is a failure in the self test or part of that may be the charging system that does not allow the unit to attempt to continue, be this by design I don’t know yet as I’m still researching.
Chances are internal hardware failure and requires replacement of the entire unit, one positive note, since the battery is probably still good you can swap it out and reserve the newer battery for later use.
I’m no APC Guru but I’ve been using these UPS backups for decades and while not having many problems with them I have indeed experienced a few.

The newer UPS's use a sense circuit so when you unplug the UPS it will not turn on if you haven't plugged it into a good grounded outlet.
Check your outlets wiring as well as your breaker panel to ground.
It’s the charging circuit. We took a massive voltage spike and that killed the it
No more cyberpower. apc only

which model is your UPS?
Had you removed the battery and test with a multimeter?

I have also a UPS which is not charging when i switch on power supply it show that your battery is full but actually it is empty....what is the problem and what i should to do for fixing this problem...?
