It fits OT-4017F, OT-4017, and OT-4017A variants alongside four additional OT-4017 sub-models. At 52.00 × 48.00 × 4.68mm, it matches the original footprint and connector exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOT-4017 series compatibility:\u003c\/strong\u003e\n    All OT-4017 variants share the same battery bay dimensions, connector pinout, and 3.7V nominal voltage rail. The BMS handshake on each model reads cell voltage and temperature from the same two-wire interface, so one cell works across the full lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the OT-4017F charge controller and confirmed the BMS accepted the new cell without triggering a protection trip. Charge current ramped normally from pre-charge trickle through constant-current to constant-voltage cutoff at 4.2V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, let the phone discharge fully until it powers off, then charge uninterrupted to 100% before using it normally. This gives the fuel gauge IC one complete reference cycle against the new cell's discharge curve — skipping it causes percentage jumps or early shutoffs in the first few days.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Pixi 4 3.5 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe OT-4017's fuel gauge IC builds its percentage model from the discharge curve of whichever cell it last fully cycled. When a new cell goes in, that stored curve belongs to the old, degraded battery. The IC maps voltage readings onto the wrong reference, so 3.85V might show as 45% on one boot and 62% on the next. One full discharge-to-shutdown followed by an uninterrupted charge to 4.2V forces the coulomb counter to reset and write a new curve. After that single calibration cycle, percentage reporting stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the modem transmits or the screen brightness spikes — both pull current fast enough to drag cell voltage below the BMS cutoff threshold before the fuel gauge catches up. On the Pixi 4 3.5, the BMS trips at approximately 3.0V under load, but the resting voltage at 25% might be 3.65V, making the shutdown look premature. A degraded or freshly installed uncalibrated cell has higher internal resistance, which amplifies the voltage sag during those load spikes. Run the calibration cycle described above first; if shutdowns continue past that point, check that the battery connector tab is fully seated — a loose contact raises effective resistance further.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392047546458,"sku":"BWCS-OTP401SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392047579226,"sku":"BWCS-OTP401SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392047611994,"sku":"BWCS-OTP401SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OTP401SL-1.webp?v=1779143125","url":"https:\/\/batteryweb.com\/products\/alcatel-one-touch-pixi-4-35-replacement-battery-37v-1300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
