Do both batteries discharge after using snow thrower?

One battery discharged some - Second Battery still fully charged.  I bought the snow thrower last year and used it only 2 times.  It seemed to have a lot of power.  This year I have used it only 2 times so far, but it does not perform as powerfully even at full throttle.  The last session took about 20 minutes.  I had put both batteries into the thrower and cleared my driveway.   As I said, it was not powerful at all.
When I brought the batteries in to recharge, one of the batteries went through the recharge cycle successfully.  Then I put the other battery on the charger, but it indicated that the battery was fully charged and did not even start up.
Is this normal, that one battery can require recharge while the other is still fully charged? And why does the snow thrower perform with less power?  It throws snow only about 1/3 to 1/2 as far as it did last year during my first two uses.
Thank you.

Very strange, Walt. It’s supposed to draw power from both batteries at the same time, not one then the other.

Try running the snowblower with one battery and see if it works with a battery in either compartment. If it doesn’t work with one battery in one of the two sides, and with equal power, you may have found the issue.
