Capacity is 4400mAh (48.84Wh). It restores portable operation to notebooks where the original cell no longer holds a usable charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eB713 and XMG M504 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions (269.00 x 50.60 x 20.00mm), connector pinout, and BMS communication protocol — which is why one cell covers the full group. The charge controller handshake is identical across the B713 and M504 series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a B713 unit. The BMS accepted the cell without fault codes, the charge circuit reached full voltage, and the protection IC responded correctly to load draw during the discharge leg.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the B713:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This triggers the BIOS battery learn cycle and clears the inaccurate health warning that appears after a cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting poor battery health immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Schenker B713 BIOS reads health data from the EEPROM stored on the old cell during every boot. When a new cell arrives, that EEPROM data is absent or mismatched, so the firmware flags it as degraded — even though the cell is new. This is not a fault with the replacement. Running one complete discharge-to-hibernate followed by a full uninterrupted charge overwrites the learn cycle data and resolves the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down hard at 20–30% charge shown on the B713\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's discharge curve. The gauge was mapped to the old cell's voltage profile, so it misjudges the voltage cliff on the new chemistry. Under combined CPU and display load, the system hits the low-voltage cutoff before the gauge catches up. Run two full discharge-to-hibernate and full-recharge cycles — by the second cycle, the fuel gauge recalibrates and the OS percentage aligns with actual cell voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409668374618,"sku":"BWCS-CLW650NB-1","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409668407386,"sku":"BWCS-CLW650NB-2","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409668440154,"sku":"BWCS-CLW650NB-3","price":97.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLW650NB-1.webp?v=1779580338","url":"https:\/\/batteryweb.com\/products\/schenker-b713-1ob-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
