It matches the OEM part number 010-00583-00 and fits the same physical envelope at 59.64 × 36.16 × 5.34mm. Swap it in when the original no longer holds a charge or the device shuts off unexpectedly during navigation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNuvi 750, 755, and 755T compatibility:\u003c\/strong\u003e\n    All three models run on the same 3.7V power rail, share an identical connector pinout, and use the same BMS handshake. One cell covers the whole trio without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge and discharge on the Nuvi platform. The BMS reported correct voltage at each stage and did not trigger a false low-battery cutoff at any point in the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use satellite acquisition:\u003c\/strong\u003e\n    After fitting this cell, power the device fully on outdoors and let it acquire a satellite fix before driving. A cold start after full power removal takes 5–10 minutes for the first fix. Subsequent warm starts drop back under a minute once the 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 at low battery on the Nuvi 750\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nuvi 750 pulls more current from the GPS receiver when signal conditions are poor — weak satellite geometry, urban canyons, or heavy cloud cover all increase receiver load. At low state-of-charge, the original aged cell sags below the voltage the receiver needs to run at full sensitivity. The result is positional drift or loss of fix, even though the display is still on. A fresh cell at full charge holds the voltage rail steady and keeps receiver sensitivity where it needs to be.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNuvi 750 shutting off without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe battery indicator on the Nuvi 750 reads percentage based on a voltage curve calibrated to a new cell. An aged or degraded cell has a flatter discharge curve, so the device reads 30% and then hits the hardware cutoff voltage almost immediately — no warning, just a sudden shutdown. After fitting this replacement, the voltage curve aligns with what the firmware expects. If shutdowns persist after fitting a new cell, run one full charge cycle to let the fuel gauge recalibrate, then confirm the device reaches 4.2V at the end of charge before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377683759194,"sku":"BWCS-IQN750SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377683791962,"sku":"BWCS-IQN750SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377683824730,"sku":"BWCS-IQN750SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IQN750SL-1.webp?v=1778771839","url":"https:\/\/batteryweb.com\/products\/garmin-nuvi-750-replacement-battery-37v-1250mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
