It replaces the original pack when the unit fails to hold a charge or shuts off unexpectedly during navigation. Voltage and capacity match the original Airis spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT610 \/ T620 \/ T920 series fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, 3.7V supply rail, and BL-L1230 connector footprint. One cell covers all four units 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 full-load discharge with the GPS receiver and display both active. The BMS held stable voltage delivery and tripped cutoff cleanly at the low-voltage threshold without unexpected drops mid-session.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst fix after battery swap:\u003c\/strong\u003e\n    After fitting this cell, power the T610 on outdoors and let it run a cold-start satellite acquisition before driving. A cold start can take 5–10 minutes for first lock — 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 accuracy reduced at low battery on the T610\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen cell voltage drops below roughly 3.5V, some Airis GPS units scale back receiver sensitivity to protect remaining charge. The unit stays on and shows a map, but satellite count drops and position drift increases. Users often blame firmware or signal, but the cause is battery voltage. Fitting a fully charged BL-L1230 restores full receiver sensitivity immediately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eT610 shuts off without warning before the battery indicator hits empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe on-screen fuel gauge on these navigators is calibrated against the original cell's discharge curve. A degraded or replacement cell with a slightly different curve will hit the BMS low-voltage cutoff before the indicator shows one bar. The unit powers off abruptly with no warning. Run two full charge-discharge cycles after fitting the BL-L1230 — the gauge recalibrates against the new cell's curve and low-battery warnings return to normal timing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377738416218,"sku":"BWCS-AT610SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377738448986,"sku":"BWCS-AT610SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377738481754,"sku":"BWCS-AT610SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AT610SL_1.webp?v=1778771838","url":"https:\/\/batteryweb.com\/products\/airis-t610-replacement-battery-37v-1250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
