It slots into the same bay as the original pack and uses the same connector. Voltage and capacity match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSarasota 8399 and 8599 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and 14.8V power rail. The BMS handshake protocol is identical across the 8399 and 8599 variants, so one cell fits both without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the Sarasota platform. The BMS accepted the cell on first insertion, reported state-of-charge correctly after two calibration cycles, and held voltage above the low-battery cutoff threshold through sustained CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning for Ni-CD:\u003c\/strong\u003e\n    Ni-CD cells need a full discharge-to-cutoff followed by an uninterrupted charge to 100% before the BIOS battery learn cycle can read the pack accurately. Skip this step and the fuel gauge IC will display erratic percentages for weeks. Run it once on day one.\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 fitting the new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Sarasota BIOS stores capacity data in EEPROM from the previous pack. When a new cell goes in, that stored data no longer matches the actual chemistry, so the health indicator flags an error — even on a brand new battery. This is not a fault with the replacement cell. Run one full discharge-to-hibernate followed by a complete uninterrupted charge; this triggers the battery learn cycle and rewrites the EEPROM values against the new cell. After two full cycles the health status clears and the indicator reads correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% remaining shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the BMS cutoff threshold under full CPU and display load, even though the fuel gauge IC is still showing charge remaining. The gauge IC has not yet calibrated against the new cell's actual voltage curve. The shutdown appears premature, but the cell is hitting its floor — typically around 10.8V under load on a 14.8V Ni-CD pack. Run two complete discharge-to-hibernate cycles and charge fully each time; the fuel gauge IC re-maps the voltage curve and the premature shutdown stops.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410831245402,"sku":"BWCS-MT8399NB-1","price":71.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410831278170,"sku":"BWCS-MT8399NB-2","price":83.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410831310938,"sku":"BWCS-MT8399NB-3","price":93.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MT8399NB-big.webp?v=1779581286","url":"https:\/\/batteryweb.com\/products\/lion-sarasota-artworker-8599-replacement-battery-148v-4400mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
