It carries a 5200mAh (19.24Wh) capacity and fits the PM450 directly using the original connector and BMS handshake. Intended for retail, warehouse, and logistics environments where scanner downtime cuts into pick rates.\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 dedicated battery bay with a keyed connector and a BMS communication line that verifies pack identity on power-up. This replacement carries the correct cell configuration and BMS signalling to pass that check without triggering an unrecognised-pack warning on the device OS.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated scan-burst sequences on the PM450 and monitored the BMS response during laser trigger inrush. The protection circuit held steady through back-to-back rapid triggers without entering overcurrent cutoff.\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 the first pick session. Scan trigger inrush current peaks when the cell is near minimum voltage — a fully charged pack prevents false BMS trips during the first high-frequency burst of the shift.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing charging error on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCharging docks on the PM450 pass a low-level current through the battery contacts before committing to a full charge cycle. If the dock contacts or the battery terminals have oxidation or debris, contact resistance climbs enough to throw a charging fault. This is not a pack failure — it is a contact issue. Wipe the gold contacts on both the battery and the cradle with a dry lint-free cloth, reseat the pack firmly, and check that the dock indicator switches to charging within 10 seconds of insertion.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner losing wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PM450 draws from the same cell for both the wireless radio and the scan trigger. During a rapid burst sequence, the combined inrush from the imager and the active radio polling can produce a short voltage sag on the battery output rail. If the cell is already below 3.5V, the BMS may interpret that sag as an unsafe drop and throttle output, briefly starving the radio before the scanner recovers. Running the shift with a fully charged pack keeps the resting voltage high enough that combined draw stays within the BMS headroom. If dropouts persist with a charged pack, check that the PM450 firmware is current — some early builds had aggressive radio power-save logic that compounded the problem.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324726902874,"sku":"BWCS-NTX800BL-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324726935642,"sku":"BWCS-NTX800BL-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324726968410,"sku":"BWCS-NTX800BL-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NTX800BL-1.webp?v=1778123083","url":"https:\/\/batteryweb.com\/products\/point-mobile-pm450-replacement-battery-37v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
