It fits directly into the original battery bay and works with the onboard fuel gauge and BMS that the MXW platform uses to report charge status to the transmitter and any paired charging station. Capacity is 1000mAh at 3.7V (3.7Wh), matching the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMXW1X and MXW6X platform fit:\u003c\/strong\u003e\n    Both transmitter types share the same battery footprint, connector pinout, and BMS handshake protocol. The MXW charging infrastructure — including the MXW-NODK docking station — reads state-of-charge data directly from the cell's protection circuit. A cell with the wrong BMS will show incorrect charge percentage or fail to initialise in the dock.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the MXW1X transmitter and MXW charging dock. The BMS initialised correctly on first insertion, charge status reported accurately on the dock display, and the protection circuit tripped at the expected low-voltage cutoff without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging contact care:\u003c\/strong\u003e\n    The MXW transmitter charges through spring-loaded pogo pins on the dock. If the battery installs loosely or the pogo pins are oxidised, the dock registers an error rather than beginning a charge cycle. Clean the transmitter's charge contacts with isopropyl alcohol before inserting a new cell — this prevents false dock errors on first charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MXW1X drops signal mid-transmission on a fresh battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MXW1X draws current from two simultaneous loads: the RF transmit stage and the DSP processing block. On a degraded or counterfeit cell, this combined draw causes a brief voltage sag below the BMS cutoff threshold, which shuts down the transmitter mid-broadcast even when the fuel gauge still shows charge remaining. A genuine 3.7V cell with the correct discharge curve holds voltage flat under this dual load. If dropouts persist after a battery swap, check that the replacement cell's nominal voltage is exactly 3.7V — cells rated 3.6V have a different discharge curve and sag earlier under RF load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReceiver loses sync every time the transmitter battery is swapped\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSome MXW system configurations require a re-pair sequence after the transmitter loses power, because the RF link parameters stored in the transmitter's volatile memory are cleared on a full power cycle. This is not a battery fault — it is normal MXW system behaviour when power is interrupted. After fitting the new cell, power on the transmitter and use the Shure Wireless Workbench or the Access Point's web interface to re-associate the transmitter with its assigned channel. Once saved, the link persists through subsequent battery swaps as long as the transmitter is not fully discharged before removal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426159886426,"sku":"BWCS-SGB906SL-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426159919194,"sku":"BWCS-SGB906SL-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426159951962,"sku":"BWCS-SGB906SL-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SGB906SL-1.webp?v=1779930458","url":"https:\/\/batteryweb.com\/products\/shure-mxw1x-replacement-battery-37v-1000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
