FM-05: The Battery Will Not Charge Or The Charger Shows A Delay Or Problem State

The pack does not reach the charger-defined full indication, remains in a temperature

Diagnostic overview

The pack does not reach the charger-defined full indication, remains in a temperature

Likely Root Causes

  • Pack temperature is outside the charger allowance
  • Pack is not seated, outlet has no power, or charger is unplugged
  • Conductive dust, liquid, or damage is present at the pack or charger

Quick Checks

  1. A sound pack reaches the charger-defined full state at an allowed temperature and powers the saw normally.

Repair Preview

  1. Move the pack and charger to a dry, ventilated room-temperature location and let a hot or cold pack normalize before continuing.
  2. - Inspect the charger cord, case, cavity, and pack for cracks, liquid, scorching, swelling, unusual heat, or conductive debris - stop for any hazard.
  3. Prove the outlet with another appliance, plug in the designated charger, and seat the pack fully.
  4. Read charging, full, temperature-delay, and problem indications only by that exact charger manual.
  5. - Cross-check with one known-good compatible pack or designated charger - retire the failed external item or use authorized service without opening either hou
