It replaces OEM part GPB-1700 and fits the GSP-1700 directly. The GSP-1700 is a portable satellite communicator used for calls, messaging, and emergency alerts in areas with no cellular coverage.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGSP-1700 platform fit:\u003c\/strong\u003e\n    The GPB-1700 form factor is specific to the GSP-1700 housing. The connector pinout carries the BMS data line the phone uses to read state-of-charge — wrong pack geometry or missing data pin causes the phone to reject the battery at boot.\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, which draw a sharp current spike as the antenna deploys and the radio locks onto a bird. The BMS held the voltage rail steady through repeated acquisition attempts without tripping into protection mode.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-weather field use:\u003c\/strong\u003e\n    In sub-zero conditions, keep this battery in an inner chest pocket until just before use. Li-ion internal resistance rises sharply below 0°C, and the acquisition current spike is large enough to trip the BMS on a cold cell — the phone will shut down before it ever registers a signal.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GSP-1700 shuts down during satellite acquisition\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSatellite acquisition is the single highest-draw event the GSP-1700 performs. The antenna mechanism, the L-band radio, and the search algorithm all draw current simultaneously. On a depleted or degraded cell, this combined load pulls voltage below the BMS cutoff threshold — typically around 3.0V — and the phone cuts power before the call connects. A fresh, fully charged cell maintains enough voltage headroom to absorb that spike. If shutdowns happen consistently at the acquisition stage rather than mid-call, the battery is the first thing to replace.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger won't accept the GSP-1700 pack after extended storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly in storage. If the pack sits unused long enough, the cell voltage drops below the charger's acceptance threshold — typically around 2.5V — and the charger reads the pack as faulty and refuses to start a charge cycle. This is a protection circuit behaviour, not permanent cell damage. Many OEM Globalstar chargers include a recovery or trickle-charge mode; plug in the pack and leave it for 30–60 minutes before the charger shifts to normal charge. If the charger has no recovery mode, a universal Li-ion charger with a boost or manual start function can bring the cell back up to 2.9–3.0V, at which point the standard charger will accept it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416118919258,"sku":"BWCS-BT170SL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416118952026,"sku":"BWCS-BT170SL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416118984794,"sku":"BWCS-BT170SL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BT170SL-1.webp?v=1779760313","url":"https:\/\/batteryweb.com\/products\/globalstar-gsp-1700-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
