It restores power to the touchscreen display and GPS receiver used for on-course yardage measurements and scoring. Voltage and capacity match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eApproach G30 fitment:\u003c\/strong\u003e\n    The G30 uses a dedicated connector and a BMS that checks cell voltage at startup. This replacement cell meets that voltage threshold, so the device boots normally without a low-battery alert on first power-on.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the G30 platform. The BMS accepted the cell without fault codes, and the GPS receiver initialised correctly through each cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-fix cold start after swap:\u003c\/strong\u003e\n    After fitting this cell, power the G30 on outdoors before your round. A full power interruption triggers a cold start — allow 5 to 10 minutes for the first satellite fix. Subsequent warm starts lock in under a minute once the almanac data is cached.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSaved courses and round data after a battery swap on the G30\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Approach G30 stores course maps and downloaded content in flash memory, which survives a full battery removal. However, active round data — current hole position, score entries in progress — sits in volatile RAM and clears the moment power drops to zero. If you swap mid-round, that session data is gone. Finish or save any active round before removing the battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eG30 shutting off without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe battery indicator on the G30 reads state-of-charge from a voltage curve calibrated to the original cell. After a battery swap, that curve is uncalibrated — the device can hit its hardware cutoff voltage before the on-screen indicator reaches the final warning bar. This is especially noticeable on an aged unit seeing a fresh cell for the first time. Run two full charge and discharge cycles to let the device recalibrate its gauge; the cutoff threshold sits at approximately 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377588863066,"sku":"BWCS-GMA300SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377588895834,"sku":"BWCS-GMA300SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377588928602,"sku":"BWCS-GMA300SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMA300SL-1.webp?v=1778771731","url":"https:\/\/batteryweb.com\/products\/garmin-approach-g30-replacement-battery-37v-700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
