It fits the Kyocera K322, K323, K325, and Cyclops flip phones. Dimensions are 53.73 × 33.81 × 5.50mm — check these against your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eK322 \/ K323 \/ K325 \/ Cyclops compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and 3.7V single-cell architecture. One cell revision covers the whole family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a K323 unit. The BMS accepted the charge IC handshake cleanly and held stable voltage across the full discharge curve without mid-cycle cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, run one full discharge down to automatic shutdown, then charge uninterrupted to 100% before use. The K322's fuel gauge IC was calibrated to your original cell's curve — one full cycle resets it against this cell so percentage readings stay accurate.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the K322 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe K322's fuel gauge IC stores a discharge curve from the original cell. When a new cell with a different impedance profile is installed, the IC predicts voltage collapse earlier than it actually occurs — triggering shutdown while usable charge remains. This is not a faulty cell. One complete discharge-to-shutdown cycle followed by a full uninterrupted charge resets the coulomb counter against the new cell's actual curve. After that cycle, the reported percentage tracks accurately to real remaining capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery compartment on the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has higher internal impedance than a broken-in one. The K322's charge IC pushes current into this higher-impedance cell, which generates more heat during the first two or three charge cycles as the cell forms. This is normal and settles as impedance drops with use. If the phone remains warm after five full cycles or the back cover feels hot rather than warm, check that the replacement cell dimensions match and the contacts are seated flat — a misaligned cell creates elevated contact resistance at the terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405147766874,"sku":"BWCS-KYK323SL-1","price":25.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405147799642,"sku":"BWCS-KYK323SL-2","price":28.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405147832410,"sku":"BWCS-KYK323SL-3","price":31.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KYK323SL-big.webp?v=1779370263","url":"https:\/\/batteryweb.com\/products\/kyocera-k322-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
