It delivers 8.4V at 2200mAh (18.48Wh) through a Ni-MH cell pack. Compatible models include the PT8000, P-Touch 110, P-Touch 200, P-Touch 300, and more than 15 additional P-Touch variants.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePT8000 and P-Touch platform fit:\u003c\/strong\u003e\n    These models share the same 8.4V battery bay, BA-8000 form factor, and connector pinout. The BMS handshake protocol is consistent across this generation of Brother label printers, so one battery pack covers the entire lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a PT8000 unit through full charge and discharge. The BMS responded correctly at both charge-complete cutoff and low-voltage protection thresholds, with no false trips during the thermal head firing cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use print sequence for Ni-MH packs:\u003c\/strong\u003e\n    After installing, charge the battery to full, then print at least five label sequences before deploying the printer. Ni-MH cells in this pack reach stable internal resistance after initial load cycling — skipping this step can cause the BMS to misread current draw and trip prematurely during the first real job.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the PT8000 stalls mid-label after sitting unused for weeks\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 20–30% per month at room temperature. A PT8000 stored for four to six weeks can drop below the minimum motor drive voltage the paper feed mechanism needs to maintain consistent torque. When the feed motor stalls mid-label, it is not a mechanical fault — it is the battery falling under load. A full charge cycle before use restores the pack to working voltage, typically above 8.0V under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFaded or uneven print on a freshly charged battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe thermal print head in the PT8000 requires a stable voltage supply to maintain consistent head temperature across the full label width. If the battery voltage sags during a print run — common in a degraded or new unconditioned pack — heat distribution across the heating elements becomes uneven, producing faded patches or light bands on the label. This is not a head fault. Run the five-label conditioning sequence described above, then retest. If print quality is still inconsistent after conditioning, check that the battery is reading above 7.8V under active print load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416000725082,"sku":"BWCS-PBA800SL-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416000757850,"sku":"BWCS-PBA800SL-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416000790618,"sku":"BWCS-PBA800SL-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PBA800SL_1.webp?v=1779759080","url":"https:\/\/batteryweb.com\/products\/brother-pt8000-replacement-battery-84v-2200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
