Hi,
Two weeks ago we had a smart 750 who had the alert Th battery is not installed properly.
The UPS stopped giving power to the devices so we needed to replace.
We replaced it with an other backup smart 750 and it worked.
Now a week later we have the same alert The battery is not installed properly.
However the batter is not working but now th ups still gived power to the devices.
Today i went to the site with a battery we tested yesterday with a multimeter.
When i put it in the ups it still says the battery is not installed properly?
Please help!!
Kind Regards,
David

You’ll need to provide the event & data logs for the problem UPS. Along with the serial number of the unit and battery installation date.
The battery will have a production date so upload a photo or state what the alphanumeric values are here.
Based only on the limited information you have provided it sounds like the battery is EOL / dead.
As such you should replace the battery to see if the problem is resolved. When a new battery is installed the following action items must be performed:
Date: The installation date must be entered as this will reset internal counters and charging tables if applicable.
Self Test: Once the new battery is (100%) charged manually initiate a self test. Either through the panel, NMC, Power Chute Software.
Calibration: Once the self test has completed allow the battery to recover and come to 100% SOC (State of Charge).
Manually initiate a battery calibration with at least (30%) attached load. Once complete the battery level indicator will be more accurate in its display while under battery only mode.
Allow the battery to recover and come to 100% SOC.
NOTE: The average service life of the battery is 2-5 years. Based on usage, temperature, and environmental conditions.
If a new battery does (NOT) solve the problem while also completing all the required steps.
The problem can be the following so check each one!
Connector / Crimp: Verify all connectors and crimps that connect to each cell is firm and tight including wiring. Look for any obvious rust and oxidation.
Fuse: Verify the fuse on the battery cartridge is fine by using a meter set to continuity.
Hardware: If all the above are fine than the UPS is faulty.
Let me know all the information requested here. 👍
