Both devices share the same battery footprint, connector, and BMS handshake protocol. Use the OEM part number WBAT1301 or P1181401746 to confirm fitment before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGo and 9560 platform compatibility:\u003c\/strong\u003e\n    Both devices run the same 3.7V battery rail and use the same physical connector and BMS communication lines. A single replacement pack covers both units without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through satellite acquisition sequences on the Go — the BMS handled the sharp current spike from antenna deployment and radio transmit without tripping. Cell voltage held steady through repeated acquisition attempts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-field pre-warming:\u003c\/strong\u003e\n    Li-Polymer internal resistance climbs sharply below 0°C. Before powering on in sub-zero conditions, keep the device in an inner jacket pocket for at least 10 minutes — a cold cell can drop enough voltage during the satellite acquisition current spike to trigger BMS cutoff before a connection is even established.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Iridium Go shuts down during satellite acquisition\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSatellite acquisition on the Go creates one of the sharpest current draws in the device's operating cycle — antenna deployment and full-power radio search run simultaneously. A degraded or cold battery may sag below the BMS low-voltage cutoff threshold during this spike, causing an abrupt shutdown before the unit ever locks onto a satellite. This is not a device fault. The cell simply cannot deliver the peak current the radio requires at that moment. Replacing the pack resolves the shutdown if the original battery has lost capacity through age or deep discharge cycling.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger LED flashing but not accepting the new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the Iridium Go charger flashes or shows no charge progress with a new or stored battery, the cell voltage has likely dropped below the charger's acceptance threshold — typically under 2.5V for Li-Polymer packs. Most chargers will not begin a standard charge cycle on a cell this low as a protection measure. To recover the pack, use a Li-Po charger with a trickle or recovery mode to bring the cell above 3.0V first. Once the cell reaches that threshold, the standard charger will accept it and complete the charge cycle normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416120852570,"sku":"BWCS-IRD956SL-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416120885338,"sku":"BWCS-IRD956SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416120918106,"sku":"BWCS-IRD956SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRD956SL-1.webp?v=1779760312","url":"https:\/\/batteryweb.com\/products\/iridium-go-replacement-battery-37v-2400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
