These convertible devices share the same battery bay geometry and voltage rail across the 3400 and 3500 generations. Capacity matches OEM spec exactly — no derating, no upsell padding.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStylistic 3400 and ST3500 platform fit:\u003c\/strong\u003e\n    Both the 3400 and 3500 generations use the same 10.8V three-cell Li-ion configuration with identical connector pinout and BMS communication protocol. Swapping between models does not require firmware changes or hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge-discharge cycles on the CP024607-01 replacement cells and confirmed the BMS communicates state-of-charge correctly to the host system. The protection circuit trips at the correct low-voltage threshold, and the charge controller accepts the handshake without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Stylistic platform:\u003c\/strong\u003e\n    After fitting this battery, run the device down until it hibernates on its own, then charge uninterrupted to 100% before unplugging. The Stylistic BIOS uses this cycle to reset its battery learn routine and clear the inaccurate capacity warnings that appear 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\"\u003eWhy the Stylistic 3400 reports poor battery health immediately after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Stylistic platform stores learned battery data in EEPROM and compares it against the new cell on first boot. Because the new cell has no charge history, the BIOS flags it as degraded or unknown — this is a data mismatch, not a fault with the replacement. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to rewrite its stored values against the new cell. After one or two cycles, the health status normalises and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eStylistic shutting down at 20–30% remaining after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage-cliff symptom — the fuel gauge IC is still calibrated to the old cell's discharge curve, so it reads 20–30% remaining at the point the new cell's voltage drops below what the CPU and display load can sustain. The system shuts down to protect itself, even though the gauge shows charge remaining. The fix is a full calibration cycle: discharge the device to automatic hibernate under normal use, then charge to 100% without interruption. After two full cycles the fuel gauge IC re-aligns to the new cell's curve and the false shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410843107418,"sku":"BWCS-FU3400NB-1","price":91.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410843140186,"sku":"BWCS-FU3400NB-2","price":107.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410843172954,"sku":"BWCS-FU3400NB-3","price":120.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FU3400NB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/fujitsu-stylistic-3400-replacement-battery-108v-3600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
