It matches the OEM part number P603562N and fits the Z430BT's internal battery slot at 61.50 × 33.50 × 6.00 mm. Swap it in when the original cell no longer holds enough charge to complete a journey.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZ430BT fit:\u003c\/strong\u003e\n    The Z430BT runs a single-cell Li-Polymer architecture at 3.7V nominal. This cell matches that voltage rail and the connector pinout, so the device's charge management circuit reads and controls the cell correctly on first boot.\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 a GPS navigator test rig. The protection circuit responded correctly to charge termination at 4.2V and engaged undervoltage cutoff before the cell reached damaging depletion depth.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after fitting:\u003c\/strong\u003e\n    After fitting this cell, power the Z430BT on outdoors and let it acquire a satellite fix before driving. A full power interruption forces a cold start — the receiver has no stored almanac data and needs 5–10 minutes for first lock versus under a minute on a warm start.\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 Z430BT\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAs cell voltage drops toward the low-battery threshold, some GPS navigators — including units in this class — reduce RF receiver sensitivity to cut current draw. On the Z430BT, this can show as position drift or a wider accuracy radius on the map. The fix is straightforward: keep the device on USB power during long routes, or charge before the battery indicator drops to one bar. A freshly charged cell at 4.2V delivers full receiver headroom from the first fix.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eZ430BT shuts off without warning before the battery indicator reads empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the battery gauge is no longer calibrated to the actual cell's discharge curve — common after the original cell has aged and capacity has dropped. The device's low-battery threshold triggers at a voltage the old cell hit quickly, but the indicator never caught up. After fitting this replacement, run one full charge-to-cutoff cycle without USB power connected. This lets the fuel gauge re-anchor its empty point to the new cell's actual 3.0V cutoff floor.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377593909338,"sku":"BWCS-BTZ430SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377593942106,"sku":"BWCS-BTZ430SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377593974874,"sku":"BWCS-BTZ430SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BTZ430SL-1.webp?v=1778771731","url":"https:\/\/batteryweb.com\/products\/binatone-z430bt-replacement-battery-37v-1300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
