As a Li-ion cell ages and internal resistance rises, voltage under motor-start load drops sharply — even if the resting voltage looks acceptable. The result is a feed motor that stalls or stutters, which the printer reports as a paper jam rather than a power fault. If clearing the paper path doesn't fix the jam, check resting voltage with a multimeter: anything below 7.2V at rest on a \"fully charged\" pack points to a degraded cell that needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415990370394,"sku":"BWCS-PNX805SL-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415990403162,"sku":"BWCS-PNX805SL-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415990435930,"sku":"BWCS-PNX805SL-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PNX805SL-1.webp?v=1779758956"},{"product_id":"seiko-dpu-414-replacement-battery-48v-1500mah-ni-mh","title":"Seiko DPU-414 Replacement Battery BP-4005 4.8V 1500mAh","description":"\u003cdiv class=\"bpw-desc\"\u003e\n  \u003ch2 class=\"bpw-desc-h2\"\u003eSeiko DPU-414 \/ DP414 — 4.8V Ni-MH Replacement Battery (BP-4005)\u003c\/h2\u003e\n\n  \u003cp class=\"bpw-desc-lead\"\u003eThis is a 4.8V 1500mAh Ni-MH replacement battery for the Seiko DPU-414 and DP414 portable thermal printers.

When the battery drops below roughly 6.8V under load, the radio module gets starved first — the printer stays on but the host device loses its connection. This looks like a pairing fault or app crash but is actually a voltage sag event. A fresh, fully charged pack eliminates the sag and keeps the radio stable through the full print queue.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRP4 printing faded or uneven text on a charged battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe thermal print head needs a stable voltage to maintain consistent head temperature across the full print width.
