It replaces the original pack when cell capacity has dropped and the tool no longer holds a working charge. Dimensions are 134.30 x 79.20 x 89.50mm — confirm these match your existing pack before ordering.\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 layout, and BMS communication protocol. One pack fits all four without any adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated trigger-pull sequences on a NovoPress-class 18V platform and monitored BMS response. The overcurrent protection reset cleanly after each inrush event without requiring a manual reset or charger intervention.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use load conditioning:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before applying full torque. This allows the BMS to profile the motor's inrush current draw and set overcurrent thresholds accurately before you hit maximum demand.\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 stalled or cold motor, current demand spikes sharply in the first 50–100 milliseconds. If the BMS registers this spike above its overcurrent threshold, it cuts the output rail to protect the cells. On a new pack, this threshold may be set conservatively until the BMS logs a few real-world inrush events. Running two half-load cycles first lets the BMS calibrate before you put the tool under full stress.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If a pack sits long enough, cell voltage can drop below the charger's acceptance threshold — typically around 2.5V per cell — and the charger refuses to begin a charge cycle. The fix is a brief boost charge using a compatible charger that supports a recovery or wake-up mode. Once cells are back above the acceptance floor, around 3.0V per cell, the charger will recognise the pack and resume a normal charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416026120282,"sku":"BWCS-MKM180PH-1","price":133.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416026153050,"sku":"BWCS-MKM180PH-2","price":157.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416026185818,"sku":"BWCS-MKM180PH-3","price":175.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKM180PH-1.webp?v=1779759485","url":"https:\/\/batteryweb.com\/products\/novopress-aco203-replacement-battery-18v-6000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
