It matches the voltage rail and connector interface of the original BBP 18 pack. Capacity is 3000mAh (54Wh) — sourced to match the OEM specification.\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 housing, and BMS handshake protocol — one pack services the full lineup without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on an 18V drill under repeated high-torque cycles. The BMS held correct overcurrent thresholds throughout, and cell voltage balanced within 20mV across full discharge.\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 maximum torque applications. This allows the BMS to profile the motor's inrush current draw and calibrate overcurrent protection thresholds before hard use.\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 cordless drill, the motor draws a spike of current — often 3–5× the running load — before it reaches operating speed. If the BMS interprets this inrush as a fault, it trips the overcurrent cutoff and the tool dies instantly on trigger pull. A fresh pack from storage is more likely to trip here because the BMS hasn't yet logged a normal inrush signature for the connected motor. Running two light-load cycles lets the BMS set its protection thresholds correctly before full-torque work.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinking red on a new pack straight from storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion chargers use an acceptance voltage check before starting a charge cycle — typically around 10V for an 18V pack. A battery stored at low charge for several months can self-discharge below this threshold, causing the charger to blink red and refuse to charge. This isn't a dead battery. Place the pack in the charger, wait 5–10 minutes, and remove and reinsert it — some chargers will initiate a trickle recovery pulse on the second attempt. If the charger still rejects the pack, check cell voltage with a multimeter; anything above 12V on an 18V pack is recoverable.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416058331226,"sku":"BWCS-MKM180PW-1","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416058363994,"sku":"BWCS-MKM180PW-2","price":114.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416058396762,"sku":"BWCS-MKM180PW-3","price":127.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKM180PW-1.webp?v=1779759860","url":"https:\/\/batteryweb.com\/products\/berner-bacag-replacement-battery-18v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
