Battery carried metal debris into the cavity
Charger was stored uncovered in a conductive-dust area
Debris has bridged or is close to external contacts
Particles have entered beyond owner-accessible surfaces
Water or cleaner entered the housing or cavity
Internal power component or wiring failed
Conductive contamination caused a short
Damaged cord, contact, or battery arced
Severe overheating progressed to active damage
Drop, crush, puncture, or impact damage
Cell or protection failure caused swelling or leakage
Water or chemical contamination reached the pack
Terminal short or overheating caused burns
A counterfeit, modified, or rebuilt pack failed
Contacts or rails are dirty, worn, or damaged

Wall screws were over-tightened or poorly placed
Plastic aged or cracked around a loaded feature
Internal mount or insulation may also be damaged
Screw heads do not engage the keyhole slots
Screw exposure or spacing is incorrect
Fasteners are not secured in sound wall material
Cord strain or pack handling pulls the charger

CHARGER BECOMES UNUSUALLY HOT OR WET, OR HAS BURNED TERMINALS

View details

The battery reaches the seated position but pulls out, lifts, or loses retention without the release button being pressed. The visible pack and charger structure appear intact.

View details

A battery intended for the charger has physical damage, swelling, leakage, wetness, burned or melted terminals, or a deformed case. It may or may not still fit the charger.

View details

PLUGGING IN THE CHARGER TRIPS A BREAKER OR GFCI

View details

POWER CORD OR PLUG IS DAMAGED, LOOSE, SCORCHED, OR HOT

View details

CONDUCTIVE DEBRIS IS IN THE BATTERY CAVITY OR VENTS

View details

One fully seated, physically sound compatible battery produces no red or yellow light, while the same DCB115 starts charging other known-good compatible packs from the same proven outlet.

View details

Independent checks show the battery charges and powers a tool normally, but the red or yellow indicator is too dim to read, remains stuck, stays on after pack removal, or does not match the label pattern.

View details

The charger has dry visible structural damage to its upper or lower housing, tabletop feet, battery rails, retention area, contact support, or rear wall-mount slots. No liquid, smoke, spark, burning, or melting is active.

View details

The red light keeps blinking while the yellow indicator stays on even after the battery and charger have naturally reached an allowed room-temperature environment.

View details

The charger housing becomes much hotter than normal charging warmth or operation repeatedly pauses as the charger heats, but there is no smoke, spark, burning odor, liquid, melting, swollen pack, or visible structural damage.

View details

The charger rocks, slides, lifts off the screws, or pulls away during battery insertion or removal even though both rear keyhole slots and the housing are visibly intact.

View details

The battery stops before the fully seated position and the charger cannot begin a normal charge. No visible charger crack, conductive debris, or swollen pack has yet been confirmed.

View details

The branch breaker or GFCI opens when the DCB115 is connected, and there is no visible cord damage, liquid, smoke, spark, burning odor, melting, or conductive debris already identified.

View details

The DCB115 develops a new loud electrical buzz or a loose-piece rattle that was not present before. There is no smoke, spark, burning odor, abnormal heat, liquid, visible housing crack, or charging interruption.

View details

A battery that reached the seated position cannot slide back out when its release button is pressed. The pack is not actively smoking, swelling, leaking, or melting.

View details

The attached cord or plug is cut, frayed, crushed, loose, discolored, scorched, or abnormally hot. There is no current smoke, spark, flame, melting charger housing, or liquid ingress.

View details

Metal chips, grinding dust, steel wool, foil, or another dry conductive buildup is visible in the battery cavity, around contacts, or at ventilation slots. No liquid or active smoke, spark, burning, or melting is present.

View details

Liquid has entered the charger or battery interface, or the charger shows smoke, sparks, burning odor, charring, melting, or active electrical arcing.
