It matches the OEM part numbers 82-171249-01, BTRY-TC7X-46MA2, and BTRY-TC70X-46MA1-01. The cell capacity is rated at 16.84Wh — consistent with the standard-capacity slot on these devices.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTC70\/TC70x\/TC71\/TC72 compatibility:\u003c\/strong\u003e\n    These four models share the same battery bay geometry, contact pinout, and BMS handshake protocol. Swapping between them works because Motorola standardised the TC7X platform battery spec across this generation — same voltage rail, same connector, same authentication sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a TC70x and monitored the BMS during cold boot, wireless association, and back-to-back scan trigger events. The BMS held voltage without tripping during the combined radio and imager inrush, and the fuel gauge reported charge state correctly throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation on the TC70x:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle and run a full charge cycle before sending it onto the floor. The scan trigger draws its highest inrush current when the cell is near minimum — a pre-charged pack prevents a false BMS cutoff on the very first pick-and-pack 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 charging error on a fresh pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TC70 series cradle communicates with the battery over a data contact before it begins the charge cycle. If that contact has oxidation or debris on either the pack or the dock, the cradle flags a fault and stops charging. This is not a battery defect — it is a contact resistance issue. Wipe the gold contacts on the new pack and the cradle slot with a dry lint-free cloth, reseat the scanner firmly, and the error clears in most cases.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner dropping wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the TC70x, the 802.11 radio and the imager draw simultaneously during a rapid scan sequence. When cell voltage dips below the radio's minimum operating threshold mid-burst, the Wi-Fi stack drops association and the scanner stalls before reconnecting. This appears as a wireless fault but the root cause is voltage sag under combined load. Charge the pack to 4.1V–4.2V before use — a fully charged cell holds the voltage rail stable under the combined draw.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324748234842,"sku":"BWCS-MOT700BL-1","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324748267610,"sku":"BWCS-MOT700BL-2","price":69.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324748300378,"sku":"BWCS-MOT700BL-3","price":76.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MOT700BL-1.webp?v=1778123056","url":"https:\/\/batteryweb.com\/products\/motorola-tc70-replacement-battery-37v-4550mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
