It fits the same battery bay and connector as the factory unit. Capacity is rated at 8.14Wh, matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTransonic 5000 and PNA-5000 fitment:\u003c\/strong\u003e\n    Both models run the same 3.7V single-cell architecture with identical connector pinout and BMS handshake requirements. One battery covers all variants in this lineup 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 charge and discharge on the Transonic 5000 platform. The onboard BMS accepted the cell without fault flags, and the charge circuit terminated correctly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after swap:\u003c\/strong\u003e\n    After fitting this battery, power the unit on outdoors in open sky before driving. A full power interruption clears the GPS receiver's ephemeris cache, so the first satellite fix takes 5–10 minutes. Subsequent warm starts drop back under a minute once the almanac rebuilds.\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 Transonic 5000\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen cell voltage drops toward 3.4V, the Transonic 5000 throttles receiver sensitivity to reduce current draw. This shows up as position jumps or loss of lock on roads with tree cover or tall buildings. The display may still show a signal bar while accuracy degrades silently. Keeping the battery above 3.6V under load maintains full receiver performance.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTransonic 5000 shutting off without any low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the battery indicator is uncalibrated against a new cell. The device's fuel gauge learned the old battery's discharge curve, so it reads the voltage incorrectly and shows adequate charge until the BMS cutoff trips abruptly. Run two full charge-discharge cycles after fitting the new cell. After the second cycle, the gauge recalibrates and the low-battery warning reappears at the correct threshold around 3.5V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377676976218,"sku":"BWCS-MD400SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377677008986,"sku":"BWCS-MD400SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377677041754,"sku":"BWCS-MD400SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MD400SL-1.webp?v=1778771802","url":"https:\/\/batteryweb.com\/products\/navigon-transonic-5000-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
