It replaces OEM part numbers P1002512, P1002514, and AK18913-001. The cell sits inside the printer's rear battery bay and powers the thermal print head, paper feed motor, and wireless radio simultaneously.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEM 220 and EM220II compatibility:\u003c\/strong\u003e\n    Both models share the same 7.4V battery rail, connector pinout, and BMS handshake protocol. The same cell works across the standard and Series II variants without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through repeated print jobs on the EM 220 platform. The BMS held a stable discharge curve across thermal head activation spikes and sustained no fault trips during motor-start draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use print sequence:\u003c\/strong\u003e\n    After installing the battery, charge it fully and print five test receipts before deploying the unit in the field. The EM 220's paper feed motor draws a calibration-level current on the first few cycles, and running those prints confirms the BMS current profile is correctly matched to the new cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the EM 220 stops printing after sitting unused for weeks\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge at roughly 2–3% per month. The EM 220's BMS has a minimum boot voltage — if the cell drops below that threshold, the printer powers on but refuses to drive the thermal head or paper feed motor. This is not a hardware fault. The BMS is protecting the cell from damage during a high-draw print cycle at low voltage. A full charge restoring the cell to 8.4V clears the lockout state immediately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBluetooth dropping mid-print job on the EM 220\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen battery charge falls below roughly 20%, the EM 220's wireless radio competes with the thermal head and feed motor for current. The radio loses that draw contest and drops the connection. The printer may show as paired on the host device but stop receiving data mid-job. Charge the battery above 50% before starting large label batches, and check that the printed voltage reading in the printer's self-test page reads above 7.0V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415999152218,"sku":"BWCS-ZEM220BL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415999184986,"sku":"BWCS-ZEM220BL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415999217754,"sku":"BWCS-ZEM220BL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZEM220BL-1.webp?v=1779759122","url":"https:\/\/batteryweb.com\/products\/zebra-em-220-replacement-battery-74v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
