It slots into the same battery compartment as the original cell and powers the camera's image capture and processing functions. Capacity is 600mAh (2.22Wh) — identical to the factory spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAgfa 4Ti compatibility:\u003c\/strong\u003e\n    The 4Ti uses a compact Li-ion cell on a 3.7V rail with a small physical footprint — 43.70 x 31.30 x 7.00mm. This replacement matches those dimensions and voltage exactly, so the battery door closes fully and the camera powers on without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the bench. The BMS held voltage within expected thresholds across the full discharge curve, and the camera body accepted the cell without throwing a rejection flag on repeated power-on tests.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge cycle on the 4Ti:\u003c\/strong\u003e\n    Run the first full charge directly through the camera body or the OEM charger before shooting. Some compact camera BMS systems need one supervised charge cycle to map the new cell's discharge curve correctly for the battery-remaining indicator to read accurately.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping on the Agfa 4Ti display after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 4Ti's battery indicator maps remaining charge against a voltage-threshold curve calibrated during the first charge cycle. A new cell that hasn't completed that cycle presents a slightly different discharge profile, so the camera misreads position on the curve. The indicator can jump from 80% to 40% or skip steps entirely. One full charge cycle from flat to full — inside the camera or OEM charger — lets the BMS recalibrate and the readout stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAgfa 4Ti showing dead battery indicator on a cell that isn't actually flat\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the replacement cell has rested at a low state of charge during storage and its open-circuit voltage has dropped below the camera's low-battery detection threshold — typically around 3.4V on a 3.7V nominal cell. The camera reads that as a depleted or faulty battery and refuses to boot. Place the cell in the OEM charger for 15–20 minutes to bring it above 3.5V, then reinsert it. The camera should power on normally from that point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333834539098,"sku":"BWCS-NP900-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333834571866,"sku":"BWCS-NP900-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333834604634,"sku":"BWCS-NP900-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP900-1.webp?v=1778213259","url":"https:\/\/batteryweb.com\/products\/agfa-4ti-replacement-battery-37v-600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
