It replaces OEM part AC35BTI and fits the original battery bay without modification. Capacity is 5.92Wh — matching the factory specification in the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e35b Titanium and Dual SIM compatibility:\u003c\/strong\u003e\n    Both variants share the same battery bay dimensions (64.60 x 44.00 x 5.10 mm), the same 3.7V nominal voltage rail, and the same connector pinout. One cell fits both models without adapter or wiring change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge and discharge on the 35b Titanium platform. The BMS accepted the charge current without interruption and the protection circuit tripped correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After fitting this replacement, run one complete discharge to automatic shutdown, then charge uninterrupted to 100% before normal use. The Archos fuel gauge IC calibrates its coulomb counter against the new cell's discharge curve during that first full cycle — skipping it causes percentage drift from the first day.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the 35b Titanium after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Archos 35b Titanium fuel gauge IC was calibrated to the original cell's internal resistance curve. A new cell has a different voltage-under-load profile, so the gauge misjudges remaining capacity. When the modem fires up for a call or the screen hits full brightness, current draw spikes and the cell voltage drops below the BMS cutoff threshold — even though the reported percentage still shows 20–30%. The fix is one full uninterrupted discharge-charge cycle, which forces the coulomb counter to remap against the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that have discharged below approximately 2.5V in storage trigger a BMS lockout to prevent damage during charge recovery. The 35b Titanium may show no response at all — no boot, no charging indicator — when this lockout is active. Connect the phone to a wall charger and leave it for 15–30 minutes without pressing the power button. The charge IC trickle-charges the cell back above the BMS re-enable threshold, typically around 2.9V, at which point the phone will show a charging screen and boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392068255834,"sku":"BWCS-AVT350SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392068288602,"sku":"BWCS-AVT350SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392068321370,"sku":"BWCS-AVT350SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AVT350SL-1.webp?v=1779143561","url":"https:\/\/batteryweb.com\/products\/archos-35b-titanium-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
