It fits the SRQ-MF97V variant as well. All three models share the same cell format, connector, and BMS handshake protocol.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMF97V, SPro2, and SRQ-MF97V compatibility:\u003c\/strong\u003e\n    These three models run off the same battery bay, voltage rail, and BMS communication line. ZTE did not change the cell specification across the variants — same part number fits all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the battery through charge and discharge cycles on SPro2 hardware. The BMS accepted the cell without error flags, voltage held steady under lamp load, and the protection circuit tripped correctly at the low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLamp brightness setting on battery power:\u003c\/strong\u003e\n    Set the projector to eco or low-brightness mode when running on battery. Full lamp brightness draws 30–40% more current than eco mode. That extra draw shortens your session noticeably without a visible improvement in most indoor presentation environments.\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 shuts off before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe projector lamp requires a higher minimum cell voltage than the battery's nominal cutoff point. When the cell drops below roughly 3.4V under lamp load, the projector's power management cuts the lamp even though the indicator may still show a partial charge. This is a voltage-sag issue, not a defective battery — it happens most often with aged cells that can no longer hold voltage under high-current draw. A fresh cell with full capacity holds above that threshold longer into the discharge cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery shows full charge but projector won't start\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA battery that reads full voltage on a meter but won't start the projector has usually tripped its BMS over-discharge protection — often after sitting discharged for several weeks. The BMS locks the output circuit and won't release it on a standard charge attempt. Connect the battery via the projector's charging port and leave it on charge for at least 30–45 minutes before attempting to power on. If the BMS re-initialises, the cell voltage will recover to above 3.6V and the projector will boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416088346714,"sku":"BWCS-ZMF970PT-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416088379482,"sku":"BWCS-ZMF970PT-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416088412250,"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\/zte-mf97v-replacement-battery-38v-6200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
