It replaces the original battery when the phone no longer holds a charge or fails to power on. Capacity figure is taken directly from the product specification — 4.07Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAmazing T3 fitment:\u003c\/strong\u003e\n    The T3 uses a compact 84.00 × 34.00 × 4.00mm cell with a 3.7V nominal rail. The connector and cell dimensions match the original bay — no modifications needed to seat the battery correctly.\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 accepted the charge IC handshake cleanly, and protection circuits tripped correctly at both low-voltage cutoff and overcharge thresholds.\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 if your T3 supports it. Run one full discharge down to auto-shutoff, then charge to 100% on standard current. This gives the fuel gauge IC a clean reference cycle against the new cell's discharge curve before high-current charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the T3 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe T3's fuel gauge IC builds its discharge model against the original cell over hundreds of cycles. When you install a new cell, that learned curve no longer matches the actual voltage-to-capacity relationship of the replacement. The IC will read state-of-charge from a mismatched map, so the percentage shown on screen drifts from reality. One full discharge-to-shutoff cycle followed by a complete charge resets the coulomb counter and lets the gauge relearn against the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the T3 after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell's internal resistance causes the terminal voltage to sag below the cutoff threshold under load — typically when the modem transmits or the screen brightness peaks. The fuel gauge still shows 20–30% because it hasn't caught up to the real voltage collapse. It is not a faulty battery; it is the fuel gauge IC working from an uncalibrated curve. Run two full discharge-charge cycles and the shutoffs should move back toward the expected low-percentage range near 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405074825306,"sku":"BWCS-ZTV900SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405074858074,"sku":"BWCS-ZTV900SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405074890842,"sku":"BWCS-ZTV900SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTV900SL-1.webp?v=1779369935","url":"https:\/\/batteryweb.com\/products\/amazing-t3-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
