It powers the display, continuous heart rate sensor, and Bluetooth connectivity. Capacity is 300mAh (1.14Wh), matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWE11098 fitment:\u003c\/strong\u003e\n    The Ticwatch Fit uses a compact 26.20 × 26.00 × 4.00mm pouch cell. The 372726 part number identifies the correct cell geometry and connector tab orientation for this chassis — a physically different cell will not seat flush against the module stack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the WE11098 platform and confirmed the BMS accepted the new cell without triggering a protection lockout. Voltage held above 3.6V through the mid-discharge window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after swap:\u003c\/strong\u003e\n    Place the watch on its magnetic charger immediately after fitting this cell and charge fully to 100% before use. The fuel gauge IC on the WE11098 loses its stored reference when the cell is disconnected — it cannot re-calibrate without a complete charge cycle starting from near-zero.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Ticwatch Fit shows 0% immediately after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe WE11098 uses a coulomb-counting fuel gauge IC that tracks charge state relative to a stored reference. Removing the cell wipes that reference entirely. When a fresh cell is inserted, the IC reads an uncalibrated state and defaults to 0% or refuses to display a value at all. This is not a fault with the replacement cell. Charge the watch fully to 100% on the magnetic charger before powering it on — that single full cycle re-establishes the gauge reference.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMagnetic charge contacts not making after reassembly\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the watch sits on the charger but shows no charging indicator, the rear contact pads have shifted during reassembly. The WE11098 back cover carries two exposed pogo-style contacts that must align precisely with the charger's magnetic pins. Re-seat the back cover fully — press each corner until the adhesive or clip engages. Check alignment by confirming the charging icon appears within 10 seconds of placing the watch on the charger. If the contact surface shows oxidation, clean with a dry cotton swab before re-seating.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416150442074,"sku":"BWCS-TWE110SH-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416150474842,"sku":"BWCS-TWE110SH-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416150507610,"sku":"BWCS-TWE110SH-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TWE110SH-1.webp?v=1779760485","url":"https:\/\/batteryweb.com\/products\/ticwatch-we11098-replacement-battery-38v-300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
