FM-18 充電器外殼、腳、導軌或者牆槽裂開或者破損

可能根本原因

  • Contacts or rails are dirty, worn, or damaged
  • Battery protection electronics are interrupting
  • Charger control or thermal electronics are failing
  • Drop, impact, crush, or sharp blow
  • Pack was forced into the charging cavity
  • Wall screws were over-tightened or poorly placed
  • Plastic aged or cracked around a loaded feature
  • Internal mount or insulation may also be damaged

快速检查

  1. A sound pack completes an uninterrupted charge, or the intermittent complete item is conclusively identified and removed from service.
  2. The damaged charger remains out of service until an authorized structural repair or complete replacement restores all insulation and retention.

维修预览

  1. Do not glue, drill, screw, tape, weld, file, or continue using the charger; the housing provides insulation, alignment, airflow, and retention.
  2. Have the complete charger evaluated by authorized service or replace it, and inspect any battery involved in the impact.
  3. Cross-test the same pack in a known-good charger and a known-good compatible pack in the DCB115.
  4. Unplug the charger and remove the battery before handling or flexing the damaged housing.
  5. Inspect without opening for exposed wiring, loose pieces, displaced contacts, sharp edges, damaged rails, or broken wall-mount engagement.
