The CAP-4 is a replacement battery cap for two 3-D-cell flashlights, the DZT-80-4 and WM-80-4. It restores the screw-on closure that holds the batteries in and completes the circuit, so a lost or damaged cap doesn't sideline the light. It is a single-purpose spare part, not an upgrade: it adds no output, modes or runtime over the original cap. Buyers rate it highly, and the main thing to check is that your light is one of the two listed models.
