2 weeks ago we saw a warning to exchange the batteries of our USV. Due to the holidays nothing was done and today we had 2 shut-offs of the USV.
Do you find this behaviour a standard? Is it enough to change batteries or may there be as well a problem with the USV itself?
If the UPS is reporting replace battery, it may be that the battery capacity is so low at this point that even a self-test or attempt to battery transfer could result in the unit turning off. I recommend turning the unit back on and reviewing the entries in the LCD menu > Logs section to see if they contain any other alerts apart from Replace Battery, and if that checks out fine, replacing the batteries as soon as possible.
