It fits handheld and bodypack transmitters in the GLXD+ ecosystem that use the 95A43507 or SB904 battery reference. Dimensions are 72.80 × 21.00 × 20.60mm — match these before ordering if you are unsure of your transmitter variant.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGLXD+ and GLXD1+ transmitter compatibility:\u003c\/strong\u003e\n    These transmitters share the same internal battery bay geometry and BMS handshake protocol across the series. Voltage regulation is handled at the transmitter level, so both handheld and bodypack units accept the same cell without firmware conflict.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on GLXD+ transmitter hardware. The BMS held the charge curve within spec and triggered protection cutoff at the correct low-voltage threshold — no erratic shutdowns or false low-battery signals during testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRF transmit draw and cell stability:\u003c\/strong\u003e\n    Sustained RF transmission pulls current in short, repetitive bursts. A cell with poor internal resistance will sag under this load and cause audio artifacts before the indicator reads low. This cell maintained stable voltage under the pulsed transmit draw across the full discharge cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GLXD+ transmitter drops audio mid-performance on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new battery that drops audio is almost always a seating issue, not a cell defect. The GLXD+ battery bay uses spring-loaded contacts, and if the pack is not clicked fully into place, contact resistance spikes under transmit load. This causes momentary voltage drops that the BMS reads as a fault, cutting power briefly before recovering. Remove the pack, check the contact pins for debris, reseat the battery until you hear the latch click, then power on.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReceiver losing lock on the transmitter after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a GLXD+ transmitter loses power and comes back on with a fresh battery, the RF link does not always re-establish automatically. The transmitter rebroadcasts its channel, but the receiver may stay locked on the last known signal state. Power cycle the receiver after swapping the transmitter battery. If the link still does not lock, hold the sync button on both units to force a fresh pairing handshake.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381522366554,"sku":"BWCS-SGX140SL-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381522399322,"sku":"BWCS-SGX140SL-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381522432090,"sku":"BWCS-SGX140SL-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SGX140SL-1.webp?v=1778901370","url":"https:\/\/batteryweb.com\/products\/shure-glxd-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
