It fits the Tecno Camon 11S, Camon iSky3, and Camon i4. Use it to restore full device operation when the original cell degrades or fails.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCamon 11S, iSky3, and i4 compatibility:\u003c\/strong\u003e\n    All three models use the same BL-34CT footprint, connector pinout, and BMS handshake protocol. The cell dimensions — 87.35 × 64.84 × 3.90mm — match the shared chassis cavity across this product line without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the BL-34CT replacement through a full charge-discharge cycle on the Camon 11S. The BMS accepted the cell, charge IC engaged correctly, and the fuel gauge IC began tracking coulomb count from cycle one. No charge rejection or cutoff errors were observed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge calibration:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's actual discharge curve before high-current charging pushes current into an uncalibrated state.\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\"\u003eThis happens when the fuel gauge IC is still calibrated to the old cell's voltage curve. The new cell hits a voltage cliff under modem or display load before the reported percentage reaches zero. The phone's power rail collapses faster than the gauge predicts. Run one full discharge to auto-off followed by a complete charge — this resets the coulomb counter baseline and resolves premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not engaging after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first cycle after installation, the charge IC may not negotiate the proprietary fast charge protocol with an uncalibrated BMS. The device defaults to standard 5V\/1A input as a safety fallback. This is not a hardware fault. Complete one full cycle at standard charge rate — fast charge handshake typically resumes from the second cycle onward once the BMS has a stable voltage reference.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391898615898,"sku":"BWCS-TEN110SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391898648666,"sku":"BWCS-TEN110SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391898681434,"sku":"BWCS-TEN110SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TEN110SL-1.webp?v=1779142626","url":"https:\/\/batteryweb.com\/products\/tecno-camon-11s-replacement-battery-38v-3200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
