症状

GBA18V40 开始进入接收轨道，但在达到正常就位和锁定位置前卡滞。
BATTERY SEATS BUT WILL NOT STAY LATCHED
A known-good compatible charger begins its normal charging cycle, but the cycle repeatedly stops, restarts, faults, or continues abnormally without reaching completion.
The pack is fully seated, the release button is pressed, and the battery still cannot be slid out without excessive force.
Battery becomes unusually hot during an otherwise normal charge
Battery loses charge rapidly while stored disconnected
室温下，放置在经过验证的兼容通风充电器中的 battery 在正常静止充电过程中比已知良好的同类 battery 明显发热，但无冒烟、肿胀或熔化现象。
电池组拆下且冷却后，一个或多个可接触的电源、信号或温度触点明显弯曲、压入、凹坑、松动或腐蚀，但无主动发热、冒烟、液体或熔化现象。
运行时间远短于匹配的已知良好 battery
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.
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.
BATTERY WILL NOT SLIDE FULLY INTO A COMPATIBLE TOOL OR CHARGER
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.
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.
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.
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.
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.
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.
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.
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.
