I purchased it as a spare at the same time as a light. Since the battery attached to the light was exhausted, it was replaced, but as soon as the battery became dark, the battery voltage was measured and it was only a few V by a few. The other two were 1.2 to 1.3V. Even though it is a high battery, was it worse around?
