It fits the 550's internal bay directly, matching the OEM form factor at 60.00 x 37.50 x 4.00mm. Swap it in when the original cell no longer holds a charge through a full navigation session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRightWay 550 fitment:\u003c\/strong\u003e\n    The 550 runs a single-cell 3.7V nominal rail with a slim Li-Polymer pack. This cell matches that voltage rail and physical envelope exactly — the BMS in the 550 communicates charge status over the same connector pinout as the OEM unit.\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 discharge on the bench, confirming the BMS accepted the pack without fault codes and that charge termination triggered correctly at 4.2V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after swap:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors and let it acquire a satellite fix before driving. The 550 performs a full cold start after any complete power interruption — first fix typically takes 5–10 minutes. Subsequent power cycles warm-start in 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 dropping at low battery on the RightWay 550\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAt low cell voltage — typically below 3.5V — some GPS receivers reduce RF receiver sensitivity to conserve power. On the 550, this can appear as position drift or a reduced satellite count on the signal bar display. The fix is not a software setting. Keeping the cell above 3.6V under load maintains full receiver sensitivity. A degraded original cell that sags under GPS draw triggers this earlier than its reported charge level suggests.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRightWay 550 shutting off without warning before the battery indicator hits empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 550 reads remaining capacity from a voltage curve calibrated to the original cell. After a full power removal and new cell installation, that calibration is reset and the device may cut off at 3.55V while still showing two bars of charge. To recalibrate, run two full charge and discharge cycles — charge to 4.2V, navigate until the unit shuts itself off, then charge fully again. After two cycles the fuel gauge tracks the new cell's actual curve accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377634050138,"sku":"BWCS-RTW550SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377634082906,"sku":"BWCS-RTW550SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377634115674,"sku":"BWCS-RTW550SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTW550SL-1.webp?v=1778771782","url":"https:\/\/batteryweb.com\/products\/rightway-550-replacement-battery-37v-900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
