It covers OT-5095 and OT-5095Y variants, along with additional OT-5095 sub-models. OEM part numbers TLp029B1 and TLp029B2 both cross-reference to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOT-5095 series compatibility:\u003c\/strong\u003e\n    The OT-5095 line shares a single battery bay spec — same connector pitch, same 3.85V nominal rail, and the same BMS handshake used across Touch Pop 4S variants. One cell fits all models in this cluster 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 full charge and discharge cycles on an OT-5095 unit. The BMS accepted charge without fault flags, the fuel gauge IC tracked state-of-charge without erratic jumps, and the protection circuit tripped correctly at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one complete discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC a full sweep of the new cell's discharge curve before the coulomb counter locks in its reference points.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the OT-5095 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe OT-5095 uses a fuel gauge IC that builds its charge-remaining model against the original cell's discharge curve. When you swap the cell, the IC still references that old curve. The result is percentage readings that lag reality — often showing 30–40% when the phone is close to shutdown. One full discharge-charge cycle without interruption forces the IC to re-map against the new cell's actual voltage profile. After that cycle, percentage reporting stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–25% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the modem or display pulls a current spike that the cell cannot sustain at that state of charge — voltage drops below the BMS cutoff threshold instantly, and the phone shuts off. It is not a faulty battery; it is the fuel gauge IC reporting a state-of-charge that is higher than the cell's actual deliverable capacity at load. The fix is the same recalibration cycle: one full discharge to auto-shutdown and a full uninterrupted charge. If shutdown still occurs after two full cycles, check that the battery connector is fully seated — a partial connection raises contact resistance and amplifies voltage sag under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392071696474,"sku":"BWCS-OTP509XL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392071729242,"sku":"BWCS-OTP509XL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392071762010,"sku":"BWCS-OTP509XL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OTP509XL-1.webp?v=1779143639","url":"https:\/\/batteryweb.com\/products\/alcatel-touch-pop-4s-replacement-battery-385v-2950mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
