It fits the standard transmitter housing used across the GLXD+ handheld and beltpack series. Swap it in when your original cell no longer holds enough charge to carry a full performance or session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGLXD+ and GLXD1+ transmitter fit:\u003c\/strong\u003e\n    These transmitters share the same internal bay dimensions, connector pinout, and BMS handshake protocol — one cell covers the full GLXD+ generation without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in a GLXD1+ beltpack and confirmed the BMS accepted the charge cycle without fault flags, held voltage through simulated transmit load, and passed the battery status read-back to the receiver correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eGLXD+ charging dock protocol:\u003c\/strong\u003e\n    Always charge this cell in the Shure SBC840 or compatible GLXD charging dock — do not attempt charging through third-party USB adapters wired to the contacts. The GLXD BMS expects a dock-side handshake to initiate the charge curve; bypassing it can leave the cell partially charged or trigger a protection lock.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVoltage sag under sustained GLXD+ transmit draw\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GLXD+ transmitter runs a 2.4GHz OFDM RF chain that pulls short, sharp current spikes during transmission bursts. A degraded or low-capacity cell sags below the BMS cutoff threshold during these spikes before the battery indicator registers low. This triggers a momentary shutdown that reads as audio dropout at the receiver rather than a battery warning. A fresh 3400mAh cell at full charge maintains headroom above that cutoff threshold through the transmit peaks.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReceiver loses lock on transmitter immediately after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter installing a new cell, the transmitter must complete a full power cycle before it re-establishes the RF link with the paired receiver. If you pull the old battery with the unit active or reinsert without powering fully off, the transmitter may come back on a mismatched channel state. Power the transmitter fully off, insert the new cell, power back on, and confirm the receiver shows a locked link — check for a solid green RF indicator on the receiver front panel.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381522268250,"sku":"BWCS-SGX140XL-1","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381522301018,"sku":"BWCS-SGX140XL-2","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381522333786,"sku":"BWCS-SGX140XL-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SGX140XL-1.webp?v=1778901385","url":"https:\/\/batteryweb.com\/products\/shure-glxd-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
