It matches the OEM part number 678102-6 and fits the same battery slot without modification. Capacity is 3000mAh (14.4Wh) — sourced to match the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e6041D and 6043D platform fit:\u003c\/strong\u003e\n    All four models in this group share the same 4.8V battery rail, connector footprint, and BMS handshake protocol. A single battery type covers the full range — no adapter or wiring change needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a 6041D under repeated trigger cycles. The BMS handled motor inrush current correctly, held voltage through the pull, and released cleanly at end of discharge without locking the pack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH break-in on first use:\u003c\/strong\u003e\n    Run the drill at half load for the first two full charge-discharge cycles before using it at maximum torque. This lets the BMS profile the motor's inrush current draw and set accurate overcurrent thresholds — skipping it can cause premature cutoffs on hard fastening tasks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS overcurrent trip on trigger pull in the 6041D\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a cordless drill, the motor draws a sharp inrush spike before settling into running current. On a Ni-MH pack at the 4.8V rail, that spike can exceed the BMS overcurrent threshold — especially if the cells are cold or the pack is new and unprovisioned. The BMS trips, cuts the output, and the drill goes dead mid-pull. The fix is to run two break-in cycles at reduced load so the BMS can calibrate its overcurrent window to the actual motor profile. After break-in, inrush trips on normal fastening tasks should stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising this pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage, and if voltage drops below the charger's acceptance threshold, the charger refuses to initiate a charge cycle — often shown as a blinking or absent indicator light. This is not a faulty battery. A brief trickle charge or a compatible charger with a recovery mode can bring the cell voltage back above the acceptance floor. Once voltage crosses that threshold — typically around 1.0V per cell — the charger recognises the pack and begins a normal charge cycle. Use a charger with a recovery or conditioning function if the standard unit won't engage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416076288090,"sku":"BWCS-MKT102PX-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416076320858,"sku":"BWCS-MKT102PX-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416076353626,"sku":"BWCS-MKT102PX-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKT102PX-1.webp?v=1779760142","url":"https:\/\/batteryweb.com\/products\/makita-6041d-replacement-battery-48v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
