It restores power to the cordless tool when the original cell pack has degraded below usable capacity. The voltage and connector configuration match the original battery format across the ACO series.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eACO 202, 203, 203plus, 203XL compatibility:\u003c\/strong\u003e\n    These models share the same 18V power rail, connector pinout, and BMS communication protocol. A single replacement cell pack covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through motor-start inrush loads on the ACO platform. The BMS handled repeated trigger-pull spikes without tripping overcurrent protection, and cell voltage recovery after each draw was consistent across cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in load protocol:\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 motor inrush current and calibrate its overcurrent thresholds before full-load operation.\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 ACO motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the ACO tool triggers, the motor draws a current spike several times higher than its steady-state load. A new or freshly charged Li-ion pack with a conservative BMS will sometimes interpret this spike as a fault and cut output. This is more likely if the pack has been sitting uncharged — cell voltage drops during storage, which narrows the BMS overcurrent headroom. Fully charge the pack before first use and allow two partial-load cycles to let the BMS recalibrate its thresholds.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool bogs under sustained load despite a full charge indicator\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA full charge LED does not rule out voltage sag under load. If the ACO tool slows or loses torque mid-task, the issue is usually high contact resistance at the battery rail or early-stage cell degradation reducing current delivery. Clean the battery terminal contacts with isopropyl alcohol and reseat the pack firmly. If sag persists after cleaning, check rail voltage under load — anything below 16.2V on an 18V pack during tool operation points to a cell that needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416058134618,"sku":"BWCS-MKM180PW-1","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416058167386,"sku":"BWCS-MKM180PW-2","price":114.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416058200154,"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\/geberit-aco-202-replacement-battery-18v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
