It replaces the original AL10A31 and cross-referenced part numbers including AL10B31, AL10G31, and BT.00603.121. The connector pinout and BMS handshake match the LT23 charging circuit directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLT23 series compatibility:\u003c\/strong\u003e\n    These models share a common 11.1V battery bay, identical connector housing, and the same BMS communication protocol over the SMBus line — which is why one cell covers the full LT2304c through LT2319u range without hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Gateway LT23 charging circuit and confirmed the BMS handshake completes correctly, charge current ramps as expected, and the protection IC triggers at both the high-voltage cutoff and the under-voltage floor without false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the LT23:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate-cutoff on a real workload — not idle — then charge uninterrupted to 100%. The LT23 BIOS uses this cycle to re-learn cell capacity and clear the inaccurate health warning that appears after any cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the LT23 shuts down at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LT23 fuel gauge IC stores charge curve data from the previous cell in EEPROM. When a new cell goes in, the stored curve no longer matches actual cell chemistry, so the gauge reads 20–30% while the real cell voltage has already dropped below the load threshold. Under full CPU and display draw, voltage sags past the BMS cutoff floor before the gauge catches up. Running one full discharge-to-hibernate then a clean charge to 100% forces the fuel gauge to re-map against the new cell and eliminates the premature shutdown.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor or unknown after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Gateway LT23 BIOS reads battery health from EEPROM data broadcast over SMBus — it is not measuring cell voltage directly. A replacement cell ships with default EEPROM values that differ from the aged cell's last-known state, which the BIOS flags as degraded or unrecognised. This is a data mismatch, not a fault with the new battery. Complete one full battery learn cycle — discharge to hibernate-cutoff, then charge to 100% without interruption — and the BIOS health status will update to normal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409824743514,"sku":"BWCS-AC260NB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409824776282,"sku":"BWCS-AC260NB-2","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409824809050,"sku":"BWCS-AC260NB-3","price":121.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC260NB-1.webp?v=1779581090","url":"https:\/\/batteryweb.com\/products\/gateway-lt23-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
