David, if both batteries are the same size and one lasts half as long as the other mowing under the same conditions, there's definitely something wrong. Contact ego customer service and they'll get you fixed up.

Here's a quick how-to on measuring your battery capacity.  If you're below 80% of the design capacity, that's a good indication of a problem, and Ego ought to replace it under warranty.  Also having this information available when you call for service should make the call go faster as you've already done the investigation into the problem, and have the results.
