It fits the OEM part number 19632 and the D45N7 cell configuration. The electrolarynx is a speech restoration device used by laryngectomy patients, so keeping this battery functional is not optional — it is the voice.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpeech and Digital XL Speech compatibility:\u003c\/strong\u003e\n    Both models share the same 7.2V Ni-MH cell stack, connector pinout, and BMS handshake protocol. The same battery services either unit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Servox charge-discharge sequence and confirmed the BMS accepted the cell, completed the verification pass, and held voltage within spec across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eElectrolarynx power-on self-test:\u003c\/strong\u003e\n    After installing this battery, allow the device to complete its full power-on self-test without interruption. The Servox BMS runs a chemistry verification at startup. Interrupting that sequence triggers a false battery fault that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm on the Servox Speech immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Servox BMS compares incoming cell voltage against an OEM reference threshold calibrated for a seasoned Ni-MH cell. A new replacement cell often sits just below that threshold on the first cycle, even after a complete charge. The device reads it as low and triggers the alarm. This is not a fault with the battery — it is the BMS learning the new cell's resting voltage profile. Run one full charge-discharge cycle before clinical use and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eServox Speech will not power on after the battery has been in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day under storage conditions. A cell that has sat for several weeks can drop below the BMS recovery threshold — typically around 5.4V for a 7.2V pack — and the device refuses to boot. Place the battery on charge immediately and leave it for a full uninterrupted charge cycle before attempting to power on the device. If the charger does not initiate, the cell may need a trickle pre-charge; confirm charger output at the contacts and check for at least 0.5V across the battery terminals before proceeding.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381435301978,"sku":"BWCS-SVX632MD-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381435334746,"sku":"BWCS-SVX632MD-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381435367514,"sku":"BWCS-SVX632MD-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SVX632MD-1.webp?v=1778900788","url":"https:\/\/batteryweb.com\/products\/servox-speech-replacement-battery-72v-230mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
