Capacity is 6800mAh (50.32Wh), matching the original specification. It fits both units — the Aera 795 and 796 share the same battery bay and connector.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAera 795 and 796 compatibility:\u003c\/strong\u003e\n    Both models run on the same 7.4V battery platform and use identical physical connectors and BMS communication lines. One cell covers both units 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 full charge and discharge cycles on the Aera platform. The BMS handshake completed correctly — charge acceptance, low-voltage cutoff, and capacity reporting all registered within factory parameters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after battery swap:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors before your first flight and let it acquire a satellite fix on the ground. A full power interruption triggers a cold start — first fix can take 5–10 minutes. Subsequent warm starts return to under a minute.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Aera 795 shuts off without warning at low battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAfter extended use, the fuel gauge IC on an aging battery loses calibration — the reported state-of-charge drifts away from actual cell voltage. The device reads 15–20% remaining and then hits the hardware undervoltage cutoff at 6.0V before the visual low-battery warning has time to fire. Fitting a new cell resets this drift because the fuel gauge re-learns from a full, healthy charge cycle. After the first full charge, run the Aera down to automatic shutdown once to allow the gauge to anchor its calibration.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy drops or receiver sensitivity reduces at low charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Aera 795 reduces power to the GPS receiver module when cell voltage sags below approximately 7.0V under load. Lower receiver power means weaker signal processing — the unit may drop from a 3D fix to a 2D fix or lose marginal satellites entirely. This is a firmware-level power management decision, not a hardware fault. Keep the cell above 50% charge during active navigation to hold full receiver sensitivity and maintain 3D fix quality.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377579458650,"sku":"BWCS-GMA795XL-1","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377579491418,"sku":"BWCS-GMA795XL-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377579524186,"sku":"BWCS-GMA795XL-3","price":104.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMA795XL-1.webp?v=1778771652","url":"https:\/\/batteryweb.com\/products\/garmin-aera-795-replacement-battery-74v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
