It replaces OEM part numbers AK17463-005 and CT17102-2. If your original battery is swelling, not holding charge, or the printer shuts off mid-job, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRW420, L405, and RW420 EQ compatibility:\u003c\/strong\u003e\n    These three models share the same 7.4V battery bay, connector pinout, and BMS communication protocol. The printer's firmware reads the battery's cell state on boot — same voltage rail means no handshake mismatch across the supported models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and discharge on RW420 hardware. The BMS held a stable voltage output through sustained thermal head activation and paper feed motor loads, with no unexpected cutoff events during the test sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration tip:\u003c\/strong\u003e\n    After installing, charge fully, then print five test receipts before field deployment. The paper feed motor draws a short current spike on each cycle — running that sequence lets the BMS log the load profile and set accurate state-of-charge readings for your printer's display.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRW420 printer goes silent mid-job — why the thermal head cuts out first\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe RW420's thermal print head pulls a concentrated burst of current every time it fires a row of dots. When cell capacity degrades, voltage sags during that burst — even if the battery indicator still reads mid-charge. The printer interprets that voltage dip as a fault condition and halts the print job before the paper feed motor ever engages. Replacing the battery restores the headroom needed to sustain head-firing current without triggering that protective halt. A healthy cell under load should hold above 6.8V at the battery terminals during active printing.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBluetooth drops mid-print job on the RW420\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe RW420's Bluetooth radio and thermal head compete for current when a print job runs. At low battery charge, the voltage rail sags enough that the radio's power threshold is crossed — the connection drops, the job is cancelled, and the printer often shows no error code. This is not a pairing or firmware issue. Charge the battery to full, relaunch the print job, and confirm the battery voltage is at or above 7.2V at rest before starting large batch jobs.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415994105946,"sku":"BWCS-ZRW420BX-1","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415994138714,"sku":"BWCS-ZRW420BX-2","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415994171482,"sku":"BWCS-ZRW420BX-3","price":77.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZRW420BX_1.webp?v=1779759123","url":"https:\/\/batteryweb.com\/products\/zebra-rw420-replacement-battery-74v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
