The Dezl 560 is a truck-specific GPS navigator built for professional drivers, running continuous turn-by-turn routing, truck-height and weight restrictions, and on-device maps. Replace this cell when the original no longer holds a charge through a full shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDezl 560 series compatibility:\u003c\/strong\u003e\n    The 560, 560LMT, 560LT, and 570 share the same battery bay dimensions and the same 3.7V power rail. The connector pinout and BMS handshake are identical across these variants, so one cell covers the full group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the Dezl 560 platform. The onboard BMS accepted the cell without fault codes, completed a full charge cycle, and held the correct voltage floor before cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start preparation after fitting:\u003c\/strong\u003e\n    After a full power interruption, the Dezl 560 loses its ephemeris data and must perform a cold satellite acquisition. Take the unit outdoors immediately after first power-on and leave it stationary — first fix typically takes five to ten minutes. Subsequent warm starts return to under a minute.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSaved routes and POIs disappearing after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Dezl 560 stores certain user data — including saved routes, custom POIs, and recent destinations — in battery-backed RAM. When power is fully removed during a battery swap, that RAM loses its state and the device falls back to factory defaults for those fields. Favourites saved to internal flash are usually retained, but trip logs and unsaved routes are at risk. Before swapping the battery, export any critical routes to a connected PC via Garmin Express or save them to the device's internal storage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDezl 560 shutting off without any low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a battery replacement, the fuel gauge IC needs a full charge-discharge cycle to recalibrate its voltage-to-percentage mapping. Until that cycle completes, the device can read 20–30% remaining while the actual cell voltage is already near the 3.0V cutoff threshold, triggering an abrupt shutdown with no visual warning. Run the unit down to auto-off on battery once, then charge it fully without interruption. After that single calibration cycle, the percentage indicator tracks accurately and warnings appear at the correct threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377637883994,"sku":"BWCS-GMD560SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377637916762,"sku":"BWCS-GMD560SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377637949530,"sku":"BWCS-GMD560SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMD560SL-1.webp?v=1778771767","url":"https:\/\/batteryweb.com\/products\/garmin-dezl-560-replacement-battery-37v-1250mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
