Drop the battery down with the flat side down about little less than an inch. If the battery falls its juice is mostly gone and not useful. If the battery stands up straight without falling, the battery is good to use! Try several times with each battery.

This would only work if you discharged your batteries with LARGE wattage --> Creating a pressure inside the battery by generating gases from the overload. This would bulge the battery a bit and causes a less firm stand.
