Common symptoms
- A sound V20 battery is fully seated, the direction button is fully forward or reverse, and the tool gives no motor sound, LED response, or chuck motion. The dead state persists when the tool is held still.
- A compatible V20 battery starts onto the tool rails but binds before reaching the normal seated and latched position.
- A room-temperature V20 battery is fully seated in a powered approved charger, but normal charging does not begin or the pack never reaches a completed-charge indication.
- The battery stays physically latched, but the motor, LED, or both cut out and return when the tool or battery is moved through ordinary working orientation.
- The direction selector moves and holds normal detents, but the chuck fails to run in one direction or rotates opposite the selected arrow.
- With the battery removed and the chuck empty, turning the sleeve rotates the spindle and motor freely instead of providing enough lock to tighten or loosen the chuck by hand.
- The direction selector is centered, but the trigger still depresses enough to start the motor or the center position cannot reliably prevent activation.
- With the chuck stopped and battery removed, the top selector cannot be moved fully into range 1 or range 2, even after the chuck is turned by hand to align the gears.
