It fits the BACAG, BACCG, BACDE, and BACDWD BL series, along with four additional compatible models. OEM part numbers are BBP 18 and 175187.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBACAG and BACCG platform compatibility:\u003c\/strong\u003e\n    These models share the same 18V battery rail, connector footprint, and BMS handshake protocol. The cell configuration and terminal layout are consistent across the series, so one replacement covers multiple tools in the lineup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through simulated drill and impact driver cycles. The BMS handled repeated motor-start inrush current without false overcurrent trips, and cell voltage recovery after load was consistent across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor inrush conditioning on first use:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before applying maximum torque. This allows the BMS to profile the inrush current draw from your specific motor before setting its overcurrent protection thresholds.\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 drill motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a drill or impact driver, the motor draws a spike of current well above its running load — sometimes three to five times higher. A new or storage-discharged pack has elevated internal resistance, which amplifies the voltage sag at that spike. If the sag crosses the BMS undervoltage threshold, the pack shuts off instantly. Charge the pack fully before the first work cycle and condition it at half load to prevent this trip.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the pack after extended storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge over time. If a pack sits long enough, cell voltage can drop below the threshold most chargers use to confirm a healthy pack — typically around 2.5V per cell. The charger sees the low voltage as a fault condition and refuses to begin a charge cycle, often showing a blinking red indicator. Use a charger with a recovery or boost mode to nudge cell voltage above 3.0V per cell, at which point a standard charge cycle will begin normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416029233242,"sku":"BWCS-MKM260PW-1","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416029266010,"sku":"BWCS-MKM260PW-2","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416029298778,"sku":"BWCS-MKM260PW-3","price":61.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKM260PW-1.webp?v=1779759627","url":"https:\/\/batteryweb.com\/products\/berner-bacag-replacement-battery-18v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
