These are compact portable scanners used in retail, warehouse picking, and asset tracking. Swap this pack when your original cell can no longer hold charge through a full shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNLS-PT800 and PT850 series compatibility:\u003c\/strong\u003e\n    All four models share the same 3.7V battery bay, connector pinout, and BMS communication protocol. One pack fits the PT800, PT850, PT850B, and PT853 without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the NLS-PT800 platform. The BMS handshake completed correctly on first insertion, charge acceptance was normal, and the protection circuit triggered at expected low-voltage thresholds without false trips during simulated scan bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep for pick-and-pack:\u003c\/strong\u003e\n    Before putting this pack into active rotation, seat the scanner in its cradle and let it complete a full charge cycle. The scan trigger draws the highest inrush current when the cell is near minimum. Starting the first shift on a fully charged cell avoids false BMS cutoffs during the first hour of use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing a charging error after fitting this new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCharging docks on the PT800 series read battery state through pogo-pin contacts on the pack's lower face. If those contacts carry oxidation, dust, or residue from the old battery, the dock reports a fault rather than starting a charge cycle. Wipe the gold contacts on the new pack with a dry lint-free cloth before seating it. Re-seat firmly — the dock needs consistent contact pressure to read the BMS correctly. If the error clears, the contact surface was the cause, not the pack or the dock.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner dropping its wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a barcode scanner fires its imager and transmits wirelessly at the same time, both draws hit the cell simultaneously. On a degraded or deeply discharged cell, this combined load pulls voltage low enough that the radio drops its connection before the BMS trips. This pack's 1100mAh cell holds voltage more steadily under that dual load than a worn original cell will. If dropouts continue after fitting a fresh pack, check that the scanner firmware is current — some PT850 firmware revisions adjusted the radio polling interval specifically to reduce this inrush overlap.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324884418650,"sku":"BWCS-NTP800BL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324884451418,"sku":"BWCS-NTP800BL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324884484186,"sku":"BWCS-NTP800BL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NTP800BL_1.webp?v=1778123334","url":"https:\/\/batteryweb.com\/products\/newland-nls-pt800-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
