It fits both \"SPro2\" and \"S Pro 2\" labelled units — same hardware, different packaging runs. Swap it in when the original cell no longer holds a charge through a full presentation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSPro2 platform fit:\u003c\/strong\u003e\n    Both SPro2 variants use the same 3.8V single-cell Li-Polymer pack with an identical connector and BMS handshake. Voltage rail and cell format match — the projector's charge management circuit recognises this cell without a firmware flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the SPro2's internal charger and confirmed the BMS accepted charge without triggering a fault state. Discharge monitoring showed the cell holds its voltage curve through the lamp's operating range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLamp brightness setting on battery power:\u003c\/strong\u003e\n    Set the SPro2 to eco or low-brightness mode when running on battery. Full brightness draws 30–40% more current from the cell than eco mode. In most indoor presentation environments, the difference in image quality is not visible, but the draw on the cell is significant.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SPro2 lamp cuts out before the battery indicator reaches empty\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SPro2's lamp requires a higher minimum voltage than the battery cutoff threshold the indicator is calibrated against. As the cell discharges and voltage sags, the lamp circuit hits its floor first — the projector shuts down even though the gauge still shows charge remaining. This is not a fault with the battery or the projector. It is a consequence of the lamp's voltage floor sitting above the cell's nominal empty point. A fresh, full-capacity cell has a flatter discharge curve and holds voltage above that lamp floor for longer before the sag occurs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSPro2 not charging — internal charger accepting no current\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the SPro2 shows no charging activity after a battery swap, the most common cause is a deeply discharged cell that has dropped below the BMS's recovery threshold. The internal charger expects the cell to present above roughly 3.0V before it begins a charge cycle. Connect the projector to mains and leave it for 15–20 minutes without powering it on — the BMS on some units will attempt a trickle pre-charge to recover the cell voltage above the threshold. If the charge indicator still does not activate after that window, verify the USB-C power source is delivering at least 9V DC to the projector's input port.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416088150106,"sku":"BWCS-ZMF970PT-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416088182874,"sku":"BWCS-ZMF970PT-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416088215642,"sku":"BWCS-ZMF970PT-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZMF970PT-1.webp?v=1779760241","url":"https:\/\/batteryweb.com\/products\/verizon-spro2-replacement-battery-38v-6200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
