I was sitting down with an open battery box with 14500s on my lap. And I got up forgetting they were there. So they fell about 18-20 inches on a wood floor. There are no visible dents on the batteries, or any other visible signs of damage. Plus, they were 14500s, so the force of the fall was considerably less than with larger batteries. But you always hear about how bad it is to drop Li-Ion batteries. Should these batteries be used? Or should they be tossed?
