It replaces part number FT453536P and restores wireless audio and communication when the original cell can no longer hold a charge. Physical dimensions are 37.50 × 33.80 × 4.00mm — verify these against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStealth 700 2Gen fit:\u003c\/strong\u003e\n    The 2nd Gen shares a distinct connector pinout and BMS handshake protocol with the base station that differs from the original Stealth 700. This cell is matched to the 2Gen specifically — the voltage rail, connector, and cell geometry are not interchangeable with the first-generation pack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge cycles on the Stealth 700 2Gen base station. The BMS completed handshake on the first dock, accepted a full charge without fault codes, and the headset powered on normally under combined audio and radio draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle base station log:\u003c\/strong\u003e\n    Dock the headset in the base station for a complete charge cycle before use. The base station needs to log the new cell before its talk-time estimate is accurate — skipping this step produces misleading charge indicators for the first few sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Stealth 700 2Gen cuts out mid-session on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe headset runs two simultaneous loads — the wireless radio and the audio amplifier — from a single 500mAh cell in a compact housing. Under combined draw, if the cell has not completed its first full charge cycle, voltage sags briefly below the BMS cutoff threshold. The firmware then shuts the headset down as a protection event, not a dead battery. One complete dock charge cycle before first use eliminates most of these mid-session dropouts.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing full charge but headset shuts off after a few minutes\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA replacement cell ships at storage voltage — typically around 3.6–3.7V — not at full charge. The base station indicator can read this as \"charged\" before the cell has actually reached 4.2V. The headset then draws down the remaining shallow capacity quickly and cuts out. Dock the headset for a full uninterrupted charge cycle until the base indicator confirms completion, then check that open-circuit voltage at the cell reads 4.1–4.2V before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428100374618,"sku":"BWCS-TEL720SL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428100407386,"sku":"BWCS-TEL720SL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428100440154,"sku":"BWCS-TEL720SL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TEL720SL-1.webp?v=1779934086","url":"https:\/\/batteryweb.com\/products\/turtle-beach-stealth-700-2gen-replacement-battery-37v-500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
