The 9201 BGAN is a field communications unit used for broadband connectivity via satellite in locations without terrestrial infrastructure. This cell replaces the original pack when the terminal can no longer hold charge through a full field session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHughes 9201 BGAN platform fit:\u003c\/strong\u003e\n    The 9201 BGAN uses a single removable Li-ion pack on a 3-cell series configuration. The BMS inside the terminal monitors cell voltage and temperature before authorising charge from the AC adapter — the connector and BMS handshake must match exactly, and this cell meets those requirements.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the bench. The BMS accepted the cell without fault codes, charge current ramped correctly through CC\/CV phases, and the protection circuit tripped at the expected low-voltage cutoff under load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration on the 9201 BGAN:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to the terminal's auto-shutoff point, then charge uninterrupted to 100%. The satellite terminal's fuel gauge IC needs this cycle to re-anchor its capacity estimate against the new cell — skipping it leaves the remaining-charge readout unreliable for the first several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 9201 BGAN reports low or unknown battery health after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 9201 BGAN stores battery state data in an EEPROM register that persists across power cycles. When a new cell goes in, the terminal reads stale cycle count and degradation data from that register and flags the battery as poor or unknown — even though the cell itself is fresh. This is not a fault with the replacement cell. Running a full discharge-to-shutoff followed by a complete uninterrupted charge allows the firmware to overwrite the old EEPROM values with accurate data from the new cell's first calibration pass.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003e9201 BGAN shutting down with charge remaining on the indicator\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The terminal's low-voltage protection triggers at roughly 9V across the 3-cell pack — but if the gauge is miscalibrated, the terminal interprets a mid-range state of charge as critically low and cuts power. The fix is two or three complete discharge-to-shutoff and full-recharge cycles, which gives the gauge IC enough data points to map the new cell's voltage curve accurately. After those cycles, the displayed percentage and actual shutoff point will align.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410832687194,"sku":"BWCS-SSP28NB-1","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410832719962,"sku":"BWCS-SSP28NB-2","price":139.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410832752730,"sku":"BWCS-SSP28NB-3","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SSP28NB-1.webp?v=1779581287","url":"https:\/\/batteryweb.com\/products\/hughes-9201-bgan-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
