It fits the STE2 variant directly, matching the original cell's voltage rail, connector, and BMS communication protocol. OEM part numbers covered include 9KY50, VXT50, 0VXT50, 51FV6, and 051FV6.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLatitude 10 STE2 fitment:\u003c\/strong\u003e\n    The STE2 uses a slim 3.50mm profile cell locked to a 15.2V four-cell Li-Polymer configuration. Any voltage mismatch trips the EC immediately and blocks charging — this cell matches that rail exactly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge, discharge, and wake-from-hibernate sequences. The BMS handshake completed cleanly, the EC accepted the cell without error flags, and charge current stepped down correctly at the 80% and 95% thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after install:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on Latitude hardware.\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 after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Latitude 10 STE2 stores battery health data in EEPROM on the old cell. When a new cell goes in, the BIOS reads that cached data as mismatched and flags the battery as degraded or unknown. This is not a fault with the replacement cell — it is a calibration state. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% and the BIOS recalculates health against the new cell's actual capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTablet 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. The reported percentage drifts from actual cell voltage, and when real voltage hits the low-cutoff threshold, the EC shuts the system down even though the display shows charge remaining. Two to three full discharge-and-recharge cycles realign the fuel gauge IC to the new cell's discharge curve. After calibration, the cutoff tracks correctly — target a resting cell voltage of approximately 14.4V at the point the system hibernates.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409660805210,"sku":"BWCS-DEL102NB-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409660837978,"sku":"BWCS-DEL102NB-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409660870746,"sku":"BWCS-DEL102NB-3","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEL102NB-1.webp?v=1779580339","url":"https:\/\/batteryweb.com\/products\/dell-latitude-10-ste2-replacement-battery-152v-1250mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
