It also fits the LinkRunner AT Network Auto-Tester. OEM part numbers ACKG2-WBP and SNBP-LION both cross to this pack.\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 battery bay, connector pinout, and BMS communication protocol — the same cell pack services the full platform 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 a full charge and discharge cycle on the AirCheck G2. The BMS reported state-of-charge correctly, and the instrument held stable voltage through the WLAN scanning and site survey load profile without tripping cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration on the AirCheck G2:\u003c\/strong\u003e\n    After installing this battery, run a full calibration cycle through the instrument's system menu before field deployment. The AirCheck G2 maps battery state during that process — skipping it causes premature low-battery warnings on the first measurement session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the AirCheck G2 sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the AirCheck G2 sat unused long enough, the pack voltage can drop below the BMS recovery threshold — typically around 2.5V per cell. At that point the BMS enters a protective sleep state and the instrument will not power on even when connected to a charger. Connecting the unit to a USB-C power source and holding the power button for 10–15 seconds can trigger a BMS wake sequence. If the pack recovers to above 3.0V, normal charging resumes from there.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAirCheck G2 shuts down during USB data transfer to a PC\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUSB data transfer adds a second simultaneous draw on top of active WLAN scanning — the combined load can pull the voltage low enough to trip the BMS undervoltage cutoff, even with a battery that showed adequate charge beforehand. This is not a faulty cell; it is a threshold event caused by the combined current spike. Charge the battery to full before transferring logs, and avoid running a live site survey during the transfer. A pack resting at 3.6V or above before you plug in the USB cable will clear this cutoff margin.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360666878042,"sku":"BWCS-NSG200SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360666910810,"sku":"BWCS-NSG200SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360666943578,"sku":"BWCS-NSG200SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NSG200SL-1.webp?v=1778616161","url":"https:\/\/batteryweb.com\/products\/netscout-aircheck-g2-replacement-battery-37v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
