Unless you specify a "lowbatt" value in you ups.conf, the shutdown
will happen when the UPS raises the "low battery" flag. How this flag

Either you "new" system draws enough extra power, or your UPS wasn't
fully charged when you did that second test, or your battery is going
bad, or a combination thereof.
