Wahrscheinliche Ursachen

A cell group cannot accept or retain charge
The protection circuit is reporting completion incorrectly
An internal connection opens after charging
The charger has a false-completion fault
Excessive internal resistance causes voltage sag
One weak cell group triggers protection
Contacts or power rails cannot carry normal current
The tool task or accessory is actually overloaded
Normal aging has reduced cell capacity
A weak cell group reaches cutoff early
High resistance wastes energy as heat
The comparison used different charge, temperature, tool or task conditions
The sealed pack has abnormal self-discharge
A cell group or protection circuit is leaking energy internally
The pack was stored hot, wet or near conductive debris
The apparent loss occurs only while installed in a tool or charger
Cooling channels are blocked
High internal resistance creates excess heat
Temperature sensing or protection electronics are faulty
The tool or accessory is creating hidden excess load
High internal resistance or cell imbalance produces excess heat
Contacts have high resistance
Temperature sensing or protection does not regulate normally
The charger or ventilation is faulty
Impact or forced insertion damaged a contact
Arcing or poor seating pitted a contact
Moisture left dry corrosion residue
A receiver contact pushed or loosened the pack contact
Drop, impact or forced insertion damaged the interface
Repeated wear cracked the latch or rail
Heat or chemical exposure distorted the plastic without an active hazard
A receiver damaged the pack interface
An internal cell support or insulator broke
A power rail or electronic assembly loosened
A fastener or shell support failed internally
Impact damaged a cell connection without opening the shell
Receiver weight or twist is loading the latch face
Debris is trapped around the release button, latch or rails
Battery housing or receiver guide is distorted from impact or heat
Debris or a raised edge blocks a rail or contact channel
The battery is misaligned or the receiver is not a compatible Bosch or AMPShare 18V interface
The pack housing, rail or receiver guide is cracked, distorted or heat-damaged
Swelling has changed the battery shape
Power contacts are contaminated or recessed
The protection electronics remain open
An internal power rail or cell connection has failed
The tool receiver has a counterpart fault
Debris prevents full latch engagement
The battery latch or receiver catch is worn, broken or held open
The battery housing or receiver rails are distorted
The receiver is not a genuinely compatible interface
Dry debris is trapped around the button
Impact damaged the button, spring or surrounding housing
The indicator window or housing is distorted
Liquid or heat damage affected the control area
Contacts are contaminated, worn, recessed or misaligned
Rails or latch allow excess movement despite apparent retention
A receiver contact block is loose
An internal power connection is movement-sensitive
The indicator module or flexible circuit has failed
A sealed internal connection to the indicator is open
The charger-complete indication was false because the battery did not store energy
The cell or protection system has failed
An indicator segment or driver has failed
The flexible circuit has an indicator-only fault
The display was read immediately after load or charge and has not settled
The battery is being compared under unmatched conditions
The pack is not fully seated or external contacts are contaminated
The battery is outside the permitted charging temperature
The charger or outlet is not actually sound
The battery contacts, temperature signal, cell stack or protection electronics have failed
Intermittent seating or contaminated contacts
Battery temperature moves outside the allowed range
One cell group, the temperature signal or protection electronics becomes unstable
The charger has an intermittent receiver fault
The battery remains internally hot or cold
Cooling channels or contacts are blocked
The temperature sensor or signal path has failed
The charger receiver is misreading the battery
Drop, crush, puncture or impact damaged the shell
A seam or fastener area failed
Age or chemical exposure embrittled the plastic
An internal support shifted and opened the case
Cell damage, internal short or thermal runaway
Liquid or conductive contamination entered the pack
Contacts or internal conductors overheated or arced
Crush, puncture, fire exposure or an unsafe charger damaged the battery

Runtime is much shorter than a matched known-good battery

Details anzeigen

The pack is fully seated, the release button is pressed, and the battery still cannot be slid out without excessive force.

Details anzeigen

A proven compatible charger gives its normal full-charge indication, yet the removed battery shows little or no charge and can run a known-good low-load tool only briefly or not at all.

Details anzeigen

At room temperature in a proven compatible tool, the pack becomes unusually hot or repeatedly protection-stops during a light intermittent task that a known-good battery completes normally.

Details anzeigen

Battery loses charge rapidly while stored disconnected

Details anzeigen

A room-temperature battery seated in a proven compatible ventilated charger becomes markedly hotter than a known-good comparable battery during a normal stationary charge, without smoke, swelling or melting.

Details anzeigen

Battery repeatedly overheats or protection-stops during light use

Details anzeigen

With the battery removed from every tool and charger, the charge-status button cannot be pressed normally, remains depressed or has broken away.

Details anzeigen

The battery shows a credible high charge or has just completed a proven charge, remains fully latched and still gives no response in a known-good compatible tool while stationary.

Details anzeigen

With the pack removed and cool, one or more accessible power, signal or temperature contacts are visibly bent, pushed in, pitted, loose or corroded, with no active heat, smoke, liquid or melting.

Details anzeigen

Battery becomes unusually hot during an otherwise normal charge

Details anzeigen

The GBA18V40 starts onto the receiver rails but binds before reaching the normal seated and latched position.

Details anzeigen

The cool dry pack has a visibly cracked, missing, loose or distorted rail, release button, latch feature or molded support, whether or not insertion has been attempted.

Details anzeigen

The charge-status button travels and returns normally, the pack has completed a normal charge in a known-good compatible charger, but no green segment lights when the button is pressed.

Details anzeigen

BATTERY WILL NOT SLIDE FULLY INTO A COMPATIBLE TOOL OR CHARGER

Details anzeigen

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.

Details anzeigen

The battery is cool and dry but the outer shell is cracked, split, punctured, missing a piece, or open at a seam, with no smoke, liquid, swelling, odor or dangerous heat.

Details anzeigen

BATTERY SEATS BUT WILL NOT STAY LATCHED

Details anzeigen

The battery reaches the normal seated position, but the release latch does not retain it and the pack can slide away without pressing the release button.

Details anzeigen

One or more green charge-status segments stay on, stay missing, or report an implausible level even though the battery charges and delivers normal low-load runtime.

Details anzeigen

The cool dry battery shell appears closed, but a new loose rattle, clunk or shifting movement is heard inside after a drop or impact, with no swelling, liquid, smoke, odor or heat.

Details anzeigen

The pack starts and runs a known-good compatible tool at no load, but output stops promptly during an ordinary matched task that a known-good battery completes.

Details anzeigen

The pack is swollen, leaking or wet, smoking, sparking, melting, giving a strong burning or chemical odor, or dangerously hot during charging, use or storage.

Details anzeigen

At room temperature, the battery is fully seated in a powered known-good compatible charger, yet the charger never enters its normal charging state.

Details anzeigen

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.

Details anzeigen

A known-good compatible charger begins its normal charging cycle, but the cycle repeatedly stops, restarts, faults, or continues abnormally without reaching completion.

Details anzeigen

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.

Details anzeigen

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.
