It fits the handheld wireless remotes used to operate MGI motorized golf caddies. Match the OEM part number NA7105 to confirm fitment before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZip, Quad, and Navigator compatibility:\u003c\/strong\u003e\n    These remotes share the same compact PCB footprint, 3.7V operating rail, and NA7105 connector pinout. One battery cell covers all listed variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Navigator remote. The BMS held cutoff voltage correctly and the cell accepted a full charge without thermal event or swelling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLi-Polymer swelling check:\u003c\/strong\u003e\n    Before installing, inspect the original cell. A swollen pouch battery can crack the remote housing if left in place. If the back cover is lifting or the cell feels puffy, remove it before powering the remote again.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MGI Navigator remote goes unresponsive at low charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IR LED in the Navigator remote requires a minimum voltage to fire a signal strong enough for the caddy receiver to recognise. As the Li-Polymer cell drops toward 3.2V, the LED output falls below the receiver's trigger threshold. The remote appears functional — buttons click, no visible damage — but commands don't register. Replacing the cell restores full LED output voltage and normal operating range.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote still not working after new battery install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe NA7105 cell uses a JST-style connector with a keyed polarity orientation. If the remote shows no response after install, the most likely cause is a reversed connection — the positive and negative contacts are swapped. Disconnect the cell, rotate the connector 180 degrees, and reconnect. Confirm the remote wakes and transmits before closing the housing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416099192922,"sku":"BWCS-MZG800SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416099225690,"sku":"BWCS-MZG800SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416099258458,"sku":"BWCS-MZG800SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MZG800SL-1.webp?v=1779760284","url":"https:\/\/batteryweb.com\/products\/mgi-zip-replacement-battery-37v-350mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
