It fits the RT40 mobile data terminal used across warehouse, retail, and logistics environments. Swap it in when the original cell degrades and can no longer hold a charge through a full shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRT40 platform fit:\u003c\/strong\u003e\n    The RT40 uses a 3.85V single-cell Li-ion pack with a multi-pin connector that carries both charging current and BMS data to the device. The HBLDT47 matches that connector and communicates battery state correctly — the scanner won't show false low-battery warnings or refuse to boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on RT40 hardware. The BMS reported state-of-charge accurately across the range, and the protection circuit responded correctly to over-discharge and short-circuit test conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation on the RT40:\u003c\/strong\u003e\n    After installing, seat the scanner in its charging cradle and run a full charge cycle before putting it into pick-and-pack rotation. The scan trigger draws a sharp inrush current, and that hit is hardest when the cell is near minimum — a fully charged pack prevents a BMS protection trip on the first trigger pull of the shift.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing a charging error on a new HBLDT47 pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eRT40 docks communicate with the battery over the multi-pin connector, not just the power pins. If the cradle flags a charging error on a fresh pack, the most common cause is contact resistance at that connector — either debris on the dock pins or an incomplete seating of the battery. Clean the contacts on both the pack and the cradle with a dry cloth, reseat firmly, and the charging handshake should re-establish. If the error persists after cleaning, check that the dock firmware is current, as older versions can reject packs with updated BMS firmware.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRT40 dropping wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring a rapid scan burst, the RT40 is drawing current for the imager, the processor, and the wireless radio simultaneously. If the cell voltage sags under that combined load, the radio subsystem can drop its connection before the scanner shows a low-battery warning. This is more likely late in a shift when the cell is below 3.6V. Check the battery status screen — if you're seeing drops below 3.5V under load, the cell is near end-of-discharge and needs to return to the cradle before the next scan run.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324712845402,"sku":"BWCS-URT410BL-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324712878170,"sku":"BWCS-URT410BL-2","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324712910938,"sku":"BWCS-URT410BL-3","price":61.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-URT410BL-1.webp?v=1778122647","url":"https:\/\/batteryweb.com\/products\/urovo-rt40-replacement-battery-385v-5100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
