It fits CUH-ZCT1H, CUH-ZCT1U, CUH-ZCT1E, and three additional regional variants. Capacity is rated at 6.66Wh — matching the stock cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCUH-ZCT1 series compatibility:\u003c\/strong\u003e\n    All CUH-ZCT1 variants share the same battery bay dimensions, connector pinout, and charge IC handshake. The LIP1522 footprint — 51.40 × 34.00 × 9.20mm — fits without modification across every regional SKU in this series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge and wireless play cycle on a CUH-ZCT1U unit. The charge IC accepted the cell without fault flags, the BMS held voltage above cutoff under simultaneous rumble and wireless load, and the controller maintained stable connection throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge conditioning after swap:\u003c\/strong\u003e\n    Run one complete wireless session to automatic controller shutdown before recharging. The DualShock 4 fuel gauge IC sets its empty reference point against the first full discharge cycle — skipping this step causes the battery indicator to read inaccurately for the first several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDualShock 4 fuel gauge jumping or freezing after a cell replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PS4 tracks battery state using a coulomb counter inside the controller, not a simple voltage lookup. When a new cell goes in, that counter holds stale data calibrated to the old, degraded cell. The indicator will jump, freeze, or show full when it isn't. One complete discharge cycle — from full charge to automatic shutoff — forces the IC to relearn the new cell's discharge curve and reset the reference points correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eController disconnecting before the battery indicator hits empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DualShock 4 wireless radio and dual rumble motors draw simultaneously under heavy gameplay, creating brief current spikes that can pull cell voltage below the BMS cutoff threshold — even when the indicator still shows one or two bars. A new cell showing this behaviour is not defective; it needs conditioning. After three to five full charge and discharge cycles, internal resistance drops and the cell sustains load voltage above the cutoff point. If disconnects persist after five cycles, check that the battery connector is fully seated — a partial connection raises contact resistance and worsens voltage sag under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377535418458,"sku":"BWCS-SP152XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377535451226,"sku":"BWCS-SP152XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377535483994,"sku":"BWCS-SP152XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SP152XL-1.webp?v=1778767309","url":"https:\/\/batteryweb.com\/products\/sony-dualshock-4-wireless-controller-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
