Question about APC Smart-UPS 1000VA UPS System
Purchased replacement batteries but cannot use them until I can get the old batteries out. Without the pull-out tab this seems impossible. I've tried everything.
You'll need to remove the cover and battery cage from the unit. I've run into this before, just take your time and be careful there are likely some sharp edges inside.
When the batteries overheat and swell, they press against the metal in the unit and get wedged in.
I found a related post about APC 3000s.

It could be that the cable to the front-panel got damaged during the battery replacement. After all these years you would think APC would improve that aspect of their design. All I can suggest is inspecting the cable and where it connects to the front panel.

You need to run recalibration on the unit. The supplied PowerChute software & cable will allow you to do this if you hook the UPS up to a PC (I know it works with the serial cable, not sure about USB). If you only have a MAC then I cannot offer a solution other than to buy the standalone PowerView device from APC. It will cost a bit more than a battery, but may save you from buying needless batteries in the future. I finally broke down an bought one, but note that I was still having the problem after the 1st recalibration. By trial and error (and maybe a vague memory) I put my MAC in sleep mode, that dropped the load to stop the lights from flashing. Then I recalibrated with a 22% load and now it finally seems better (lights no longer flashing). This was with a Smart-UPS 1000.
Let me know if that helps.

disconnect one terminal of the battery then measure charging voltage betwen +ve and -ve it should be 13.8vdc for one 12v battery if charging voltage is not present then battery is ok then connect ammeter to measure the current in Ampere .take care it should be in series if current if no current then battery must ok opern the ups there is a charger transformer measure i/p voltage to transformer if not present then check i/p path if present then check diodes at o/p of charger if faulty replace it also check capacitor and regulator ic if faulty replace it your problem must be solved

Testimonial: "There is no way to check the water in the batteries as thry are sealed. I found out that after a load is applied it goes on battery for a few seconds "
