Capacity is 3000mAh (54Wh). It uses the same connector and voltage rail as the OEM pack, so no adapters or modifications are needed.\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 housing, and BMS communication protocol. Swapping between them requires no reconfiguration — the BMS handshake completes on first insertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through repeated motor-start cycles on an 18V tool platform. The BMS handled inrush current spikes without tripping, held voltage above the low-cell cutoff threshold, and balanced cells across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in for press tool applications:\u003c\/strong\u003e\n    On first use, run the tool at partial load for two cycles before applying full pressing force. This lets the BMS profile the motor inrush draw and set overcurrent thresholds before it encounters maximum torque demands.\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 surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a cordless press tool, the motor draws a spike of current before it reaches operating speed — often three to five times the steady running load. If the BMS flags that spike as an overcurrent fault, it cuts power instantly and the tool drops out mid-cycle. This pack's BMS is calibrated for the inrush profile of the ACO-series motors, so it distinguishes a normal start surge from a genuine fault. A cold pack makes this worse because Li-ion internal resistance rises below 5°C, amplifying the voltage sag at the moment of inrush.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows no activity or blinks fault after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs discharged below roughly 2.5V per cell will sit outside the acceptance window most chargers use to detect a valid pack — the charger sees the low cell voltage and refuses to begin a normal charge cycle. If this happens, some chargers have a recovery or trickle-charge mode that brings cells back up to 3.0V before switching to full charge. If your charger has no recovery mode, verify each cell reads at least 2.5V with a multimeter before assuming the pack is dead. Cells that recover to 3.0V and then charge to a full 18V (4.2V per cell on a 4S pack) are generally usable.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416058036314,"sku":"BWCS-MKM180PW-1","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416058069082,"sku":"BWCS-MKM180PW-2","price":114.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416058101850,"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\/novopress-aco203-replacement-battery-18v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
