It replaces OEM part numbers BATRPFIDG3-6102, PFIDG-00-13-3S2P-0, and PFIDG-03-17-3S2P-0. It restores unplugged operation on laptops where the original cell has degraded or failed completely.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS1 Plus and VIA 15 compatibility:\u003c\/strong\u003e\n    Both models share the same 3S2P cell configuration, connector pinout, and BMS handshake protocol — which is why these OEM part numbers cross-reference across both platforms. The battery management system talks to the same EEPROM interface on each chassis.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a representative platform, confirming the BMS negotiated correctly, charge current tapered at the expected threshold, and no protection trips occurred during load transitions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the S1 Plus and VIA 15:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100% before unplugging again. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on these Schenker models.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the S1 Plus shuts down at 20–30% remaining after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the S1 Plus measures remaining capacity by tracking voltage curves calibrated to the original cell's discharge profile. A new cell has a slightly different curve, so the IC hits its low-voltage threshold earlier than the percentage shown on screen suggests. The laptop interprets that voltage floor as a system-critical cutoff and shuts down immediately. Running two or three full discharge-to-hibernate cycles lets the gauge IC re-map against the new cell's actual curve and eliminates the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as \"poor\" or \"replace soon\" after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis warning comes from EEPROM data the BIOS carried over from the degraded original cell — it does not reflect the new cell's actual condition. The BIOS battery learn cycle has not yet run against the replacement, so the stored charge-cycle count and capacity estimate are still tied to the old unit. Perform the calibration cycle described above: full discharge to hibernate cutoff, then a single uninterrupted charge to 100%. After that cycle completes, the BIOS re-reads the battery data and the warning clears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409522720858,"sku":"BWCS-MDX250NB-1","price":122.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409522753626,"sku":"BWCS-MDX250NB-2","price":141.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409522786394,"sku":"BWCS-MDX250NB-3","price":154.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDX250NB-1.webp?v=1779579941","url":"https:\/\/batteryweb.com\/products\/schenker-s1-plus-replacement-battery-1155v-7800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
