Query: This is a lemon

First light worked only for several minutes, then quit. No matter how much I charged it, it would only work for several minutes. I exchanged for a new one. The new one worked fine for three hours. After an adequate re-charge, per instructions, it (like the first one) ran for less than a minute before quitting. I tried several charges and each time it ran only for less than a minute (or just a few seconds). This is not the Lezyne that I thought I knew, as previous products I purchased were excellent.
