Both models use the same battery bay, voltage rail, and connector spec, so one SKU covers both. Capacity figure is taken directly from the product data — 17.76Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSport 9460 and Sport 2 compatibility:\u003c\/strong\u003e\n    Both printers share an identical battery bay, 7.4V nominal rail, and connector pinout. The BMS handshake is the same across both model lines, so this cell communicates correctly with the charge controller in either unit 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 discharge under load profiles matching the Sport 9460's thermal print head and paper feed motor draw. The BMS held output voltage stable across the draw spike at print initiation and did not trip on motor start.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install print sequence:\u003c\/strong\u003e\n    After installing this battery, charge it fully, then run five consecutive test receipts before deploying in the field. The paper feed motor requires consistent current delivery to confirm the BMS current profile is correctly matched to the new cell — skipping this step can cause feed errors on first real use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVoltage sag during thermal print head activation on the Sport 9460\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe thermal print head on the Sport 9460 draws a short, sharp current spike the moment a print job starts. A degraded or partially charged battery cannot sustain voltage through that spike, which causes the BMS to momentarily throttle output. This shows up as a corrupted first line on the receipt or a complete print failure. A fresh cell at full charge — 8.4V off the charger — delivers the current headroom the head needs to fire cleanly from the first dot line.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBluetooth dropping mid-print job on the Sport 2\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen battery charge drops below roughly 20%, the Sport 2's radio module begins competing with the thermal head for available current. The radio loses that fight and the Bluetooth link drops, cancelling the job. This is not a firmware or pairing issue — it is a voltage sag problem. Keep the battery above half charge during multi-receipt runs, and recharge when the printer's indicator reaches one bar.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416001314906,"sku":"BWCS-MH6017BL-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416001347674,"sku":"BWCS-MH6017BL-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416001380442,"sku":"BWCS-MH6017BL-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MH6017BL-1.webp?v=1779759079","url":"https:\/\/batteryweb.com\/products\/sierra-sport-9460-replacement-battery-74v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
