It matches the original cell's voltage rail and connector footprint. OEM part numbers WJ5R2 and 4F5YV both cross-reference to this unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrecision 3510 and Latitude E5570 shared platform:\u003c\/strong\u003e\n    Both models run on the same 11.4V three-cell architecture and share identical battery connectors and BMS handshake protocols. One cell covers both, which is why the OEM part numbers carry across the two product lines.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Precision 3510 chassis and confirmed full BMS handshake, stable charge acceptance from 0% to 100%, and no thermal flags during discharge under sustained CPU and GPU load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after install:\u003c\/strong\u003e\n    After fitting this battery, run the system down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning Dell's firmware posts whenever a new cell is detected.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDell's BIOS reads EEPROM data embedded in the battery pack and compares it against charge history from the previous cell. A freshly installed cell has no cycle history, so the firmware flags it as degraded — even when the cell is new. This is a firmware interpretation issue, not a hardware fault. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% writes new baseline data to the BIOS and clears the warning. After two to three full cycles, the health indicator should read normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't calibrated against the new cell's actual voltage curve. The old calibration data causes the OS to misread remaining charge, and the system hits a hard voltage cutoff while the display still shows capacity remaining. It is not a faulty cell. Force a full discharge to hibernate, let it sit for five minutes, then charge to 100% without interruption — repeat this twice. After two calibration cycles the gauge will track accurately and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409744756826,"sku":"BWCS-DEP351NB-1","price":133.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409744789594,"sku":"BWCS-DEP351NB-2","price":153.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409744822362,"sku":"BWCS-DEP351NB-3","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEP351NB-1.webp?v=1779580647","url":"https:\/\/batteryweb.com\/products\/dell-precision-3510-replacement-battery-114v-7300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
