It restores standalone navigation and location tracking on this vehicle-mount unit. Capacity is 1100mAh (4.07Wh) — matching the original cell's specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGeoVision 5850HDDVR fitment:\u003c\/strong\u003e\n    This cell matches the voltage rail, physical footprint (50.86 × 34.00 × 5.73 mm), and connector orientation of the 5850HDDVR. The BMS handshake on this unit is straightforward — no proprietary authentication challenge between cell and device.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and load discharge on the GPS platform. The BMS held cutoff cleanly at the low-voltage threshold and accepted a full charge cycle without thermal flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-fix cold start after fitting:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors and let it acquire a satellite fix before driving. A full power interruption triggers a cold start — expect the first satellite lock to take 5–10 minutes. Subsequent warm starts drop back under a minute once almanac data is cached.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy reduced when the 5850HDDVR battery drops below 20%\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAt low state of charge, some GPS receivers step down receiver sensitivity to reduce current draw and extend remaining power. On the 5850HDDVR, this shows up as position drift or a slower position refresh on-screen. The GPS chip prioritises power headroom over signal processing at voltages approaching the BMS cutoff threshold. Keeping the cell above 3.6V under load holds the receiver in full-sensitivity mode.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003e5850HDDVR shuts off without warning before the battery indicator hits zero\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe on-screen battery indicator on this unit reads estimated state of charge, not a direct voltage measurement. A degraded original cell has a steeper voltage drop curve, so the device hits the BMS cutoff threshold — typically around 3.0V under load — while the indicator still shows one or two bars. Fitting a new cell with a flat discharge curve recalibrates the effective warning window. After the first full charge and discharge cycle on the replacement, the indicator reading and actual remaining capacity align more closely.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377604460634,"sku":"BWCS-PRV585SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377604493402,"sku":"BWCS-PRV585SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377604526170,"sku":"BWCS-PRV585SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PRV585SL-1.webp?v=1778771746","url":"https:\/\/batteryweb.com\/products\/prestigio-geovision-5850hddvr-replacement-battery-37v-1100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
