It also fits the 6804, MF4, and 600 series mobile units sharing the same connector and voltage rail. Swap it in when the original pack no longer holds a charge through a full shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePW40 and 6804 series compatibility:\u003c\/strong\u003e\n    These models share the same 7.4V battery bay, connector pinout, and BMS handshake protocol. One pack covers the full platform — no adapters, no firmware differences to account for.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a PW40 unit. The BMS balanced cells correctly, trip thresholds matched OEM spec, and the printer's charge indicator reported state-of-charge accurately throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep for the PW40:\u003c\/strong\u003e\n    Before running a print job, seat the new pack in the PW40 and let it charge to full. The PW40's thermal print head draws a short inrush spike on every label — starting from a low cell state can cause the BMS to trip and interrupt mid-job printing.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the PW40 stops mid-print-job on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PW40's thermal print head pulls a brief high-current spike each time it fires a label. On a new but uncharged pack, cell voltage drops sharply during that spike. The BMS reads it as an undervoltage fault and cuts output to protect the cells. This looks like the printer died, but it's a protection trip, not a hardware fault. Charge the pack to at least 7.2V before the first print run and the trips stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePW40 battery icon showing full but printer cuts out early\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually means the printer's fuel gauge is reading a state-of-charge estimate that hasn't calibrated to the new pack yet. The PW40 uses a voltage-based SOC estimate that takes one full charge-discharge cycle to anchor correctly. Run the pack from full charge down to automatic shutoff, then charge it fully without interruption. After that cycle, the charge indicator tracks accurately against actual cell voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43325005922394,"sku":"BWCS-IPT40BL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43325005955162,"sku":"BWCS-IPT40BL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43325005987930,"sku":"BWCS-IPT40BL-3","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IPT40BL-1.webp?v=1778123426","url":"https:\/\/batteryweb.com\/products\/intermec-pw40-replacement-battery-74v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
