It fits the NetScout Aircheck G2 and AirCheck G2 WLAN Tester — portable Wi-Fi analysis tools used for RF measurement, security scanning, and network diagnostics in the field. It also fits the LinkRunner AT Network Auto-Tester, which shares the same battery bay and connector format.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAircheck G2 and LinkRunner AT compatibility:\u003c\/strong\u003e\n    Both instruments share the same 3.7V single-cell Li-ion architecture, connector pinout, and BMS handshake protocol. One battery covers both platforms without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the Aircheck G2's full boot and scan cycle. The BMS held stable voltage through RF channel scanning and security sweep loads without triggering a protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run a complete scan session until the instrument triggers a low-battery alert, then charge fully before field deployment. The Aircheck G2 maps cell state during active use, and skipping this step causes the fuel gauge to report incorrect charge levels during your first real survey.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAircheck G2 shutting down mid-scan with no low-battery warning\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS triggers an overcurrent cutoff during a simultaneous RF sweep and security scan — both processes draw from the same cell at the same time, and the combined load spike briefly exceeds the protection threshold. A degraded original battery makes this worse because internal resistance climbs as cells age, amplifying the voltage sag under load. A fresh pack with lower internal resistance handles the combined draw without hitting the cutoff threshold. If shutdowns continue after fitting a new pack, check that no background USB data sync is running at the same time as active scanning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePack won't charge or respond after the instrument sat unused for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eExtended storage at low state-of-charge can push a Li-ion cell below the BMS recovery threshold — typically around 2.5V — and the protection circuit latches off, blocking charging entirely. The charger sees no draw and assumes no battery is present. To recover the pack, leave it connected to the Aircheck G2 charger for at least 30–40 minutes without interruption; some BMS circuits require a trickle voltage to wake before accepting a full charge cycle. If the instrument still shows no charging activity after that window, the cell voltage has likely dropped below the recovery floor and the pack will need replacement. Replacing with a freshly shipped pack avoids this — storage-new cells ship at around 3.6–3.8V, well above the lockout threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360666452058,"sku":"BWCS-NSG200XL-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360666484826,"sku":"BWCS-NSG200XL-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360666517594,"sku":"BWCS-NSG200XL-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NSG200XL-1.webp?v=1778616161","url":"https:\/\/batteryweb.com\/products\/netscout-aircheck-g2-replacement-battery-37v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
