It replaces OEM part numbers including 312-0724, 312-0725, N950C, N956C, T116C, and U661H, among others. The battery slots into the standard Vostro battery bay and connects via the original locking latch.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVostro 1310 \/ 1510 \/ 1320 platform fit:\u003c\/strong\u003e\n    These Vostro models share the same 11.1V three-cell battery rail, connector pinout, and BMS handshake protocol — one cell covers all of them without any modification to the bay or contacts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on a Vostro 1310 unit. The BMS negotiated correctly with the Dell EC, charge current tapered normally at the 4.2V\/cell threshold, and no protection-circuit trips occurred under combined CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to the hibernate-cutoff point on a single uninterrupted session, then charge straight to 100% without interruption. This forces the Dell BIOS to complete its battery learn cycle and clears the false \"poor health\" warning that appears after every 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 battery health as poor immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Dell Vostro BIOS reads health data from the battery's EEPROM chip, which stores cycle count and rated capacity from the previous cell. A brand-new cell arrives with EEPROM values that do not yet match the BIOS's learned baseline, so the firmware flags it as degraded even though capacity is full. This is not a fault with the replacement cell. One complete discharge-to-hibernate followed by an uninterrupted full charge resets the learn cycle and updates the BIOS health register to reflect the new cell's actual state.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC's calibration table still maps to the old cell's voltage curve. Under full CPU plus display load, the new cell hits a steeper voltage drop at lower state-of-charge than the IC expects, so the system reads safe charge remaining right up until the cell voltage collapses below the protection threshold. The fix is two to three full calibration cycles — discharge to hibernate cutoff each time, then charge to 100% uninterrupted. After those cycles the fuel gauge re-maps its curve to the new cell and the percentage readings stabilise. Confirm the gauge is tracking correctly by checking battery voltage in HWMonitor: it should read above 10.8V at 20% indicated.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410811191386,"sku":"BWCS-DE1310NB-1","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410811224154,"sku":"BWCS-DE1310NB-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410811256922,"sku":"BWCS-DE1310NB-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DE1310NB-1.webp?v=1779581142","url":"https:\/\/batteryweb.com\/products\/dell-vostro-1310-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
