Symptoms

Almacenado solo, el paquete pierde carga sustancial sin uso.
The battery latches normally and works while still, but charging or tool power stops, restarts, or flickers when the pack or receiver is gently moved.
The bit passed initial insertion, but backs out, falls free, or loses drive while the chuck body stays secure.
The motor can be heard, but the front output remains still in both directions with the bit removed.
The trigger returns normally and power drops, but the anvil repeatedly coasts instead of stopping promptly.
The chain is hard to pull around the bar, the bar becomes unusually hot, or smoke appears without an electrical odor.
The drill stops early or gives far less runtime than expected without unusual heat.
THE BATTERY WILL NOT SEAT, LATCH, RELEASE, OR STAY SECURE
Charger green LED stays on
THE BATTERY OR CHARGER WILL NOT BEGIN OR COMPLETE A CHARGE
THE DRILL WILL NOT START WITH A CHARGED KNOWN-GOOD BATTERY
The direction lever will not reach forward, reverse, or center lock, or the selected position does not hold.
The drive operates normally, but the work light stays dark, flickers, or cuts in and out with trigger use.
A known-good compatible charger begins its normal charging cycle, but the cycle repeatedly stops, restarts, faults, or continues abnormally without reaching completion.
After a normal full charge, the battery loses a large amount of indicated charge or usable low-load runtime while stored by itself in a cool, dry place.
Battery loses charge rapidly while stored disconnected
WORKLIGHT COMES ON, BUT THE MOTOR WILL NOT START
A straight bit traces a visible circle at no load instead of rotating on a stable centerline.
After a normal full charge, the battery delivers usable power but substantially less work than a comparable known-good pack in the same tool, task and conditions.
At no load the motor starts, but speed has a dead band, surges, cuts out, or ignores trigger pressure.
