It fits the 7370 directly, matching the original connector, BMS handshake protocol, and cell voltage. Use the OEM part numbers WY7CG and XCNR3 to verify fitment against your existing battery label before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLatitude 7370 fit:\u003c\/strong\u003e\n    The 7370 uses a two-cell 7.6V pack with a specific 5-pin smart connector. This replacement matches that pin layout and communicates with the Dell EC firmware so the system recognises the battery rather than flagging an unknown device on POST.\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 Latitude 7370 unit. The BMS negotiated correctly with the Dell embedded controller, charge termination triggered at the expected 8.7V cutoff, and no protection-circuit trips occurred during load testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the 7370:\u003c\/strong\u003e\n    After fitting, run the laptop down to hibernate cutoff under normal use — do not force-shutdown. Then charge uninterrupted to 100% without using the machine. This resets the BIOS battery learn cycle and clears the inaccurate 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 poor battery health immediately after fitting the new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Latitude 7370 BIOS reads health data from EEPROM registers that were written by the original factory cell. When a new cell arrives, those registers don't yet reflect real-world cycle data, so the BIOS flags it as degraded — even though the cell is new. This is a firmware state issue, not a hardware fault. Run one full discharge-to-hibernate followed by an uninterrupted full charge. After two to three cycles the BIOS health indicator will update to reflect the actual cell condition.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down hard at 20–30% shown on the fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the 7370 calculates remaining capacity against a charge profile built from the old cell's impedance curve. A new cell has lower internal resistance and a different voltage-versus-capacity slope. The gauge underestimates remaining charge and calls shutdown well before the cell is actually empty. This is not a defective battery — it is a calibration mismatch. Force the IC to relearn by completing three full discharge-to-hibernate and charge-to-100% cycles without interruption. After the third cycle, shutdowns at false percentages stop and the gauge stabilises around the correct voltage floor of approximately 6.0V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409722998874,"sku":"BWCS-DEL137NB-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409723031642,"sku":"BWCS-DEL137NB-2","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409723064410,"sku":"BWCS-DEL137NB-3","price":100.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEL137NB-1.webp?v=1779580542","url":"https:\/\/batteryweb.com\/products\/dell-latitude-13-7370-replacement-battery-76v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
