It matches the OEM dimensions at 52.78 × 34.23 × 10.95mm and uses OEM part references 523450L110 and 1S2PMX. Capacity is rated at 8.14Wh — identical to the factory spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTravelPilot 500 and 700 fitment:\u003c\/strong\u003e\n    Both units share the same battery bay dimensions, connector orientation, and single-cell 3.7V architecture. The BMS handshake is identical across both models, so one cell covers either unit without modification.\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 a TravelPilot unit. The BMS accepted the cell without fault flags, balanced correctly at full charge, and held voltage within the expected window across a standard navigation session.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst fix after installation:\u003c\/strong\u003e\n    After fitting this cell, power the GPS fully on outdoors before use. The unit performs a cold start after any full power interruption — first satellite acquisition can take 5–10 minutes. Subsequent warm starts drop to under a minute once the almanac 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 battery draining faster during active navigation than standby\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe TravelPilot draws significantly more current during active routing than when idle. The GPS receiver runs continuously, the processor recalculates turn-by-turn data, and the display stays at full brightness — all three loads run simultaneously. On a fresh cell this is normal behaviour, not a fault. Reducing display brightness is the single most effective way to lower draw during long drives.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTravelPilot 500 shutting off without warning at low battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the battery indicator loses calibration after a cell swap. The fuel gauge reads remaining charge as a percentage based on learned discharge curves from the old cell — after replacement, those curves no longer match. The device hits the BMS low-voltage cutoff before the on-screen warning triggers. Run two full charge-to-discharge cycles to let the gauge recalibrate against the new cell; the warning should align to cutoff at or above 3.4V after that.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377678581850,"sku":"BWCS-BTP700SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377678614618,"sku":"BWCS-BTP700SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377678647386,"sku":"BWCS-BTP700SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BTP700SL-1.webp?v=1778771839","url":"https:\/\/batteryweb.com\/products\/blaupunkt-travelpilot-500-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
