It fits the 00385000, 8051275002, PowerImpact 12, PowerLED 12, and related compact cordless tools in the 10.8V platform. Cell capacity and connector pinout match the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e10.8V platform compatibility:\u003c\/strong\u003e\n    These models share a common 10.8V three-cell Li-ion architecture with the same slide-rail connector and BMS communication protocol. Swapping packs across the platform works because the charger handshake and pack ID signal are identical across all 6.25439 fitments.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge-discharge cycles on a PowerImpact 12 and monitored BMS behaviour under motor-start inrush. The overcurrent protection triggered at the correct threshold and reset cleanly between trigger pulls without latching fault states.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use load conditioning:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before applying maximum torque. This lets the BMS sample the motor's inrush current draw and calibrate its overcurrent thresholds before you push the pack hard.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on motor-start inrush in compact 10.8V drill-drivers\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCompact 10.8V tools draw a sharp current spike the moment the trigger is pulled — often two to three times the running current. On a new or recently stored pack, the BMS has not yet profiled the motor load and may apply a conservative overcurrent limit. If the pack cuts out instantly on trigger pull, it is almost always this threshold being hit, not a cell fault. Running two or three light-load cycles first gives the BMS the data it needs to stop false-tripping.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool bogs under sustained load but recovers when you release the trigger\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is voltage sag — cell voltage drops under sustained current draw and the tool's motor controller interprets it as a low-voltage cutoff condition. The most common cause on a replacement pack is high contact resistance at the slide-rail terminals. Clean both the battery and tool contacts with isopropyl alcohol, then reseat the pack firmly. If the sag continues, check resting voltage after a full charge — it should read 12.6V; anything below 12.0V at rest points to a cell imbalance worth investigating.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416007999578,"sku":"BWCS-MTP120PX-1","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416008032346,"sku":"BWCS-MTP120PX-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416008065114,"sku":"BWCS-MTP120PX-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTP120PX-1.webp?v=1779759303","url":"https:\/\/batteryweb.com\/products\/metabo-00385000-replacement-battery-108v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
