A fully charged pack becomes unusable after a short cool, dry storage interval even though it was not left in a tool or charger.

View details

The pack was immersed, splashed internally, left in rain, or exposed to salt water, bleach, chlorine, or another conductive/corrosive liquid.

View details

Charging starts or stops when the battery is moved or held

View details

Tool output cuts in or out when the securely latched battery moves

View details

The pack becomes rapidly or painfully hot during charging, storage, or ordinary tool use, but no active venting, flame, leakage, or visible swelling is present.

View details

The cylinder pack stops before the normal seated position or requires abnormal force in a compatible Bosch 12V Max tool or approved charger.

View details

A safe-looking battery does not enter a normal charge cycle or never reaches the exact charger's defined full indication after correct seating.

View details

An externally sound, fully inserted BAT414 pack produces no usable output in a compatible Bosch 12V Max tool.

View details

The pack inserts fully but one or both side release tabs do not retain it, or the pack can pull out without pressing both tabs.

View details

The charger indication or charge cycle changes when the seated battery is touched, shifted, lifted, or held in one position.

View details

A compatible tool starts normally, then loses all battery output suddenly during an ordinary task while the trigger remains commanded.

View details

The pack is fully or partly engaged but cannot be removed by operating the normal release and pulling straight.

View details

The tool continues to run but power is continuously low, uneven, or surging instead of stopping completely.

View details

A fully seated and retained pack powers the tool only in certain positions or interrupts when the tool or battery is moved, without a normal overload stop.

View details

The battery is actively smoking, hissing, venting gas, sparking, burning, melting, leaking, or rapidly escalating in temperature.

View details

The battery provides normal initial power but reaches depletion much sooner than a comparable healthy 2.0 Ah Bosch 12V Max pack in the same ordinary task.

View details

The stable pack is cracked, crushed, punctured, burned, deformed, swollen, corroded, or has damaged contacts, barriers, insertion stem, or release tabs.
