It matches the OEM voltage rail and physical footprint for a direct swap without hardware modification. Install it when the original cell no longer holds charge or when Windows reports degraded battery health.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLatitude 5320 \/ 7320 platform fit:\u003c\/strong\u003e\n    These models share an 11.4V three-cell architecture with the same connector pinout and BMS handshake protocol. Part numbers MHR4G, 1PP63, 727CG, 9JM71, HDGJ8, 4M1JN, and TN2GY are all cross-compatible across this generation — Dell used multiple OEM codes for the same physical cell depending on build region and supplier batch.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Latitude 7320 unit and confirmed the BMS completed its initialisation handshake, charge current ramped correctly through CC\/CV phases, and the BIOS battery page reported capacity without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this cell, discharge the laptop fully until it hibernates, then charge uninterrupted to 100% without interruption. This forces the fuel gauge IC to re-learn the new cell's actual capacity curve and clears the false \"poor health\" warning the BIOS displays after every cell swap.\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 health data from the battery's EEPROM, which stores charge cycle count and rated Wh from the original cell's firmware. A replacement cell resets that EEPROM, so the BIOS flags the mismatch as degraded health even when the new cell is fully functional. Running one complete discharge-to-hibernate followed by a full uninterrupted charge allows the fuel gauge IC to write fresh baseline data. After two to three full cycles, the health status in Dell Power Manager normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% charge shown on screen\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 actual voltage curve. The OS reads a fuel gauge estimate from the old curve, so the displayed percentage does not match real cell voltage — the laptop hits the hardware low-voltage cutoff while the screen still shows 20–30% remaining. It is not a fault with the replacement cell. Run two full discharge-to-hibernate cycles and the gauge recalibrates; shutdowns should move to below 5% reported charge, which is normal BMS low-voltage protection at approximately 9.0V pack voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409534287962,"sku":"BWCS-DEL732NB-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409534320730,"sku":"BWCS-DEL732NB-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409534353498,"sku":"BWCS-DEL732NB-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEL732NB-1.webp?v=1779579965","url":"https:\/\/batteryweb.com\/products\/dell-latitude-13-5320-replacement-battery-114v-3650mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
