The M17480 runs on a compact 3.6V Li-ion platform — this cell is a direct voltage-compatible swap at 3.7V nominal, which is standard for this chemistry. Capacity comes in at 2900mAh (10.73Wh), a step up from the original 1.1Ah pack.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eConfirmed fit — M17480, M17730, M17766:\u003c\/strong\u003e These models share the same 3.6V Li-ion battery platform, connector footprint, and BMS handshake, which is why one cell covers all three.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles — the BMS held voltage steady under load and triggered the low-voltage cutoff cleanly without requiring a manual reset.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after storage:\u003c\/strong\u003e If the screwdriver has been sitting unused for several months, run a full charge before the first use — Li-ion cells at low state of charge can take longer to wake the BMS and accept current normally.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy capacity increased without changing voltage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe original Mannesmann pack ships at 1.1Ah to keep cost and size minimal for a compact screwdriver. This replacement uses a 2900mAh cell in the same physical envelope — 66.65 x 19.50 x 18.50mm — so it fits the battery compartment without modification. Higher capacity at identical voltage means more charge stored per cycle, not a change in how the tool operates. The motor, torque rating, and RPM all stay the same.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScrewdriver powers on but cuts out under load — here's the cause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the tool starts normally but dies mid-screw when resistance increases, the original battery's BMS is likely tripping the overcurrent protection prematurely — a sign the cells have degraded. A worn cell can't deliver the brief current spike a 3.5Nm torque demand requires. Swapping to a fresh cell with an intact BMS resolves this — the protection circuit responds to actual fault conditions, not aged-cell voltage sag.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175821246554,"sku":"BWCS-WGF300VX-1","price":30.07,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175821279322,"sku":"BWCS-WGF300VX-2","price":34.49,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175821312090,"sku":"BWCS-WGF300VX-3","price":37.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WGF300VX-1.webp?v=1775236276","url":"https:\/\/batteryweb.com\/products\/mannesmann-m17480-replacement-battery-37v-2900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
