I bought the 21" push mower (no self-propel) and have had 5 mows in so far on our 0.4 acre yard. The first time, the mower worked great. The battery stayed green on the mower for the entire yard. The second time, I almost finished the whole yard again before it died (literally a few more passes). The last 3 times I've noticed the battery life go down noticeably. Now, I understand the grass is getting thicker, and a couple of times it may have been wetter than normal, but I'm down about 3/4 of my lawn on a single charge (the battery lasts about 40-45 minutes of mowing on a very flat yard). I'm afraid it is going to keep going down...
I have kept my battery plugged in on the charger, and am wondering if I'm hurting battery life by doing this. I'm aware that the manual says to unplug the battery charge and remove battery from charger.

Please contact support.  You should not have to remove the battery.  Ieave my batteries in the chargers all of the time, for the past 3+ years without issue. 

Some things to check.

Is your blade sharp?  These blades require a lot of maintenance because they dull so easily, and nothing wears out the battery faster on these things than a dull blade.  I sharpen mine after each cut, excessive, but it is quite dull after each cut.

Are conditions different?  More moisture in the grass?  thicker, taller?  Everything affects battery life.
