It fits the internal battery bay directly and connects via the original ribbon or connector. Capacity is 4.63Wh, matching OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNuvi 465, 465T, 465LTM compatibility:\u003c\/strong\u003e\n    All three variants share the same battery bay dimensions (60.50 × 37.00 × 5.50mm), the same 3.7V supply rail, and the same connector footprint. The BMS on each model uses an identical voltage cutoff curve, so this cell communicates correctly with the protection circuit across all three.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a Nuvi 465 unit. The BMS accepted charge from the OEM cradle without fault flags, held voltage above 3.5V through the navigation load cycle, and tripped the low-voltage cutoff at the correct threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after fitting:\u003c\/strong\u003e\n    After a full power interruption, the Nuvi 465 loses its ephemeris data and requires a cold GPS start. Power the unit on outdoors with a clear sky view and allow 5–10 minutes for first satellite lock. Subsequent warm starts will lock in under a minute once the data is rebuilt.\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 Nuvi 465\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nuvi 465 reduces receiver sensitivity when battery voltage drops toward the lower end of the discharge curve. This is a power-saving behaviour built into the GPS chipset — the receiver draws less current, but positional accuracy and signal-to-noise ratio both degrade. Users see this as route recalculations increasing or position jumping between streets. Fitting a fresh cell and keeping voltage above 3.6V during active navigation keeps the receiver running at full sensitivity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNuvi 465 shutting off without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe battery indicator on the Nuvi 465 is calibrated to the original cell's discharge curve. After the original cell ages, or when a new cell first goes in, the indicator can read incorrectly — the device hits the hardware voltage cutoff before the on-screen warning reaches empty. This is not a fault with the replacement cell. Run two full charge-and-discharge cycles through normal navigation use and the indicator will re-calibrate to the new cell's actual curve. After calibration, the low-battery warning will fire above 3.5V as expected.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377673764954,"sku":"BWCS-IQN460SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377673797722,"sku":"BWCS-IQN460SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377673830490,"sku":"BWCS-IQN460SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IQN460SL-1.webp?v=1778771802","url":"https:\/\/batteryweb.com\/products\/garmin-nuvi-465-replacement-battery-37v-1250mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
