It matches the OEM voltage rail, connector pinout, and physical footprint at 60.65 × 57.80 × 4.50mm. Swap it in when the original cell no longer holds usable charge or fails to power on.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCink Peax and Cink Peax 2 compatibility:\u003c\/strong\u003e\n    Both handsets use the same PEAK 2 battery format — identical voltage rail, connector, and BMS communication lines. One cell covers both models 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 full charge and discharge on the Cink Peax platform. The BMS accepted the cell without fault codes, and the charge IC completed a full constant-current to constant-voltage transition at 4.2V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge reset:\u003c\/strong\u003e\n    After installation, disable fast charging and run one complete discharge down to automatic shutdown, then charge to 100% uninterrupted. This lets the fuel gauge IC map the new cell's discharge curve before resuming normal use.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Cink Peax fuel gauge IC retains the old cell's discharge curve in memory after a swap. When the modem or display draws a short current spike, the new cell's actual voltage drops faster than the stored curve predicts — the system sees what looks like a collapse and triggers an emergency cutoff. This is not a faulty cell. Run one full discharge-to-shutdown cycle without interruption and let the phone charge back to 100%. After that cycle the coulomb counter recalibrates and the premature shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reports wrong battery percentage after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the Cink Peax uses a stored charge table built from the original cell's impedance and capacity. A new cell has different internal resistance, so the IC's state-of-charge estimate drifts — you may see the percentage jump, stall at an odd number, or read 1% before shutting down. The fix is a full recalibration cycle: discharge the phone completely until it shuts itself off, then charge straight to 100% without unplugging. One complete cycle rewrites the reference table against the new cell and percentage reporting stabilises at 3.7V mid-charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404155322458,"sku":"BWCS-WKN310SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404155355226,"sku":"BWCS-WKN310SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404155387994,"sku":"BWCS-WKN310SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WKN310SL-1.webp?v=1779369096","url":"https:\/\/batteryweb.com\/products\/wiko-cink-peax-replacement-battery-37v-1750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
