It slots into the same battery bay as the original pack and runs on the same voltage rail. Capacity is sourced from product data — 2000mAh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eACO203, ACO203-XL, ACO202, ACO401 compatibility:\u003c\/strong\u003e\n    These four models share the same 18V battery platform, connector pinout, and BMS communication protocol. A battery that handshakes correctly on one will handshake correctly on all four — no firmware or connector differences between them.\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 and sustained press cycles on the ACO203. The BMS handled the trigger-pull current spike without tripping, and cell voltage recovery after each cycle stayed within expected bounds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in procedure for new pack:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before full-torque pressing operations. This allows the BMS to profile the motor's inrush current draw and set overcurrent protection thresholds accurately before you push maximum load.\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 ACO203 motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eEvery time you pull the trigger on a cordless press tool, the motor draws a brief inrush current spike that can be three to five times the steady running current. On a new or cold battery, the BMS may read that spike as an overcurrent fault and cut the output before the motor spins up. This is a protection threshold issue, not a battery defect. Two break-in cycles at partial load let the BMS log the motor's actual inrush profile and adjust its trip point accordingly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the new pack after extended storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that have sat in storage can drop below the charger's acceptance threshold — typically around 2.5V per cell. When cell voltage is too low, the charger's detection circuit sees a dead or shorted pack and refuses to begin a charge cycle, often signalling with a blinking or solid red LED. The fix is to briefly connect the pack, wait 30 seconds, and disconnect — some chargers will attempt a trickle pre-charge pulse on reconnect. If the charger still refuses, check that the terminal contacts on both the pack and charger are clean and making firm contact before concluding the pack is unrecoverable.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416029331546,"sku":"BWCS-MKM260PW-1","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416029364314,"sku":"BWCS-MKM260PW-2","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416029397082,"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\/novopress-aco203-replacement-battery-18v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
