Symptoms

A compatible charger continues to report its temperature-delay state after the battery has stabilized at room temperature and the charger works normally with another compatible battery.
A straight bit traces a visible circle at no load instead of rotating on a stable centerline.
The drill or battery becomes rapidly or severely hot, or little cooling air can move through the tool vents.
Smoke, burning odor, melting, liquid, active sparks, swelling, hissing, or severe pack damage is present.
The forward/reverse button sticks, commands the wrong rotation, or center does not lock the trigger.
The included compatible charger shows no status light and will not begin charging a sound pack.
The motor can be heard, but the chain remains stationary or only twitches while the trigger is held.
A tool-free knob is frozen, cross-threaded, spins without effect, will not clamp the bar, or cannot hold the set tension.
A known-good compatible charger begins its normal charging cycle, but the cycle repeatedly stops, restarts, faults, or continues abnormally without reaching completion.
The collar will not align or hold, or screwdriving clutch cut-off is absent or premature.
