It powers both the flash capacitor charging circuit and the exposure control system. Swap it in when the camera refuses to fire or the flash fails to cycle.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e350 and 360 Land Camera fit:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions and voltage rail. The PA000796 footprint — 35.00 × 18.80 × 16.70mm — seats correctly in either body without modification to contacts or bay clearance.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through repeated flash-charge cycles on a 350 body. The cell held stable output voltage through successive capacitor charges without voltage sag that would cause underexposed frames or incomplete flash recycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFlash capacitor load tip:\u003c\/strong\u003e\n    Li-MnO2 chemistry has a relatively flat discharge curve, but the Land Camera's flash capacitor draws a sharp current spike at the start of each recycle. If the camera is stored loaded for weeks, fire one test flash before shooting a roll to clear any surface charge buildup on the capacitor.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots on the 350\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Land Camera 350 uses a mechanically timed shutter with no electronic shot counter, so the only feedback you get from a fading cell is a sluggish flash recycle or a dim strobe. The flash capacitor needs a sustained current draw to charge to full firing voltage — typically around 300V on the capacitor side. A cell at end of life cannot sustain that draw and the capacitor charges to a lower voltage, producing underlit frames. If recycle time between shots feels longer than two seconds, the cell is due for replacement.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera shutter fires but flash does not trigger\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eOn the 350, the shutter and flash circuits are electrically separate. A depleted cell can still supply enough voltage to trip the shutter solenoid — roughly 1.5V is sufficient — while failing to drive the flash capacitor charge circuit, which requires the full 3V supply. This means the camera appears to work but every frame comes out dark indoors. Check the cell voltage with a multimeter: anything below 2.7V under load means the cell needs replacing, even if the shutter still fires.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333580062810,"sku":"BWCS-PMT350MC-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333580095578,"sku":"BWCS-PMT350MC-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333580128346,"sku":"BWCS-PMT350MC-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PMT350MC-1.webp?v=1778212994","url":"https:\/\/batteryweb.com\/products\/polaroid-350-automatic-land-camera-replacement-battery-3v-1350mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
