It fits the PM450 directly and matches the OEM part number 450-BTEC. Capacity is 25.16Wh — same spec as the factory pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePM450 platform fit:\u003c\/strong\u003e\n    The PM450 uses a keyed battery bay with a specific connector layout and BMS handshake. This pack replicates the OEM voltage rail and communication protocol, so the device recognises it on insertion without prompting a fault code.\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 a PM450 unit. The BMS held stable across scan trigger bursts and Wi-Fi polling intervals, with no mid-cycle cutoffs or erratic state-of-charge readings on the device screen.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle and run a full charge cycle before putting it into pick-and-pack rotation. The scan trigger draws the highest inrush current when the cell is near minimum — a fully charged pack on the first shift prevents the BMS from tripping on that initial load spike.\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 on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA charging error on a fresh pack is almost always a contact resistance issue, not a fault with the battery or dock electronics. The PM450 cradle reads pack state through the same gold pogo contacts it uses to charge — if those contacts have oxidation or debris, the dock throws an error before current even flows. Wipe the contacts on the battery and the cradle with a dry cloth, then reseat the pack firmly until it clicks. If the error clears, charge proceeds normally; if it persists, check that the cradle firmware is current, as older versions can misread a new pack's initial voltage as out-of-range.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner losing Wi-Fi connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the PM450, simultaneous scan trigger activation and Wi-Fi transmission create a combined inrush that briefly sags the voltage rail. If the cell voltage is already low, this sag can cross the BMS low-voltage threshold, causing the radio to drop before the cell actually hits cutoff. The result is a momentary disconnection mid-burst — users often blame the access point, but the cause is on the battery side. Keep the pack above 20% charge during high-frequency scanning runs, and check the device's reported battery voltage in Settings — if it reads below 3.5V under load, swap the pack before the next shift.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324725395546,"sku":"BWCS-NTX800BX-1","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324725428314,"sku":"BWCS-NTX800BX-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324725461082,"sku":"BWCS-NTX800BX-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NTX800BX-1.webp?v=1778123083","url":"https:\/\/batteryweb.com\/products\/point-mobile-pm450-replacement-battery-37v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
