My 2012 would show 60+ Miles with 4 bars gone before battery was replaced.
Because as mentioned NUMEROUS times in this forum, the range estimator, more accurately called the "Guess-O-Meter" or "GOM", bases its calculations on very recent driving conditions. If this car was driven on a steady uphill and then recharged, it is using the most recent "fuel" economy calculations to come up with that figure. Since you already have a Leaf you should have known of this behavior by the GOM even if you are a recent member of this forum.
I live about a 1000 foot elevation higher than where I work, so if I plug in after I get home and charge to 100%, it often would only show about a 60 mile range especially if I used the freeway instead of city streets. But if I use city streets to get to work, when I arrive it's now showing 100 miles because it's all been downhill.
The only way to know the battery's true state of health is to use an app like LeafSpy or LeafStat and the appropriate OBDII dongle for your smartphone.
