It fits the transmitter module that sends real-time wind speed and direction data to compatible Garmin chartplotters. Voltage and capacity match OEM spec exactly — no modification required.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003egWind Wireless and Transducer compatibility:\u003c\/strong\u003e\n    Both the standard gWind Wireless (010-01248-00) and the Transducer variant share the same battery housing, connector, and BMS handshake. One cell covers both units.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the gWind platform. The BMS accepted the cell without error, completed a full charge cycle, and the unit resumed normal transmission to the chartplotter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after swap:\u003c\/strong\u003e\n    After fitting this cell, power the unit on and allow the connected chartplotter to re-acquire the wind sensor signal before heading out. A full power interruption resets the sensor link — allow 5–10 minutes for the chartplotter to re-establish data from the transmitter on first power-up.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the gWind Wireless drops off the chartplotter display at low charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells lose voltage gradually as capacity depletes, but the gWind transmitter has a hard cutoff threshold — typically around 2.0V under load. Below that, the unit stops transmitting before the battery reads visually \"dead.\" The chartplotter shows no wind data, not a low-battery warning. This is a transmitter-side cutoff, not a chartplotter fault. Fitting a fresh cell and cycling power restores transmission immediately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWind data frozen on chartplotter after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a full power interruption, the gWind transmitter and chartplotter must re-pair over the 2.4GHz ANT wireless link. The chartplotter may show the last known wind reading as frozen rather than blank. Go to the chartplotter's sensor settings and trigger a fresh device scan. Once the transmitter is re-detected, live wind data resumes — confirm the reading is updating by watching for direction changes over 30 seconds.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377600528474,"sku":"BWCS-GMW117SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377600561242,"sku":"BWCS-GMW117SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377600594010,"sku":"BWCS-GMW117SL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMW117SL-1.webp?v=1778771731","url":"https:\/\/batteryweb.com\/products\/garmin-gwind-wireless-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
