The MT9083 and SM201-6 are the OEM part numbers this pack cross-references directly. Capacity and connector pinout match the original spec so the instrument's power management system reads the pack correctly from first boot.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMT9082 series compatibility:\u003c\/strong\u003e\n    All MT9082 variants share the same 11.1V three-cell Li-ion architecture, connector housing, and BMS handshake protocol. Swapping between variants in the field is common — this pack covers the full lineup without any adapter or firmware change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the MT9082's sustained RF sweep load and probe power-up sequence. The BMS held stable across the initialisation current spike and did not trip into protection mode during back-to-back measurement sessions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle from the instrument's system menu before field deployment. The MT9082 maps battery state during calibration — skipping this step causes the low-battery indicator to trigger prematurely on the first measurement session, even with a full charge.\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 MT9082 sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge over time. If the pack drops below approximately 2.5V per cell during extended storage, the BMS enters deep-discharge lockout and the instrument will not power on — even connected to the charger. The BMS protection circuit blocks charge current to prevent cell damage until a recovery voltage is applied. To recover, connect the original Anritsu charger and leave it for at least 90 minutes before attempting to power on; the charger's trickle stage is what re-enables the BMS. If the pack fails to respond after two hours on charge, cell voltage has dropped below the recovery threshold and the pack needs replacement.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings drifting or logging sessions resetting unexpectedly mid-sweep\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSustained RF sweep loads draw more current than standby, and if cell capacity has degraded, voltage sags enough mid-session to cause the MT9082's processor to reset or drop logged data. This is not a firmware fault — it is a voltage dropout event. A healthy pack at this load holds above 10.5V under sustained draw; anything below that threshold triggers the instrument's undervoltage protection. If resets correlate with long sweep sessions rather than cold starts, check pack voltage under load with a multimeter at the battery terminals — a reading below 10.8V during active use confirms the pack needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360772882522,"sku":"BWCS-GME300MD-1","price":130.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360772915290,"sku":"BWCS-GME300MD-2","price":154.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360772948058,"sku":"BWCS-GME300MD-3","price":172.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GME300MD-1.webp?v=1778616259","url":"https:\/\/batteryweb.com\/products\/anritsu-mt9082-replacement-battery-111v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
