It fits the same battery bay and uses the same three-contact connector as the factory cell. Voltage and capacity match the OEM spec exactly — 3.7V nominal, 8.88Wh total.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTouch Pro \/ TyTN III platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. One cell covers all of them without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Touch Pro unit and monitored the BMS through charge and discharge. The protection circuit held cutoff at the correct thresholds and the charge IC accepted the cell without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge-to-charge cycle. The fuel gauge IC on the Touch Pro calibrates its coulomb counter against the cell's discharge curve — skipping this step causes erratic percentage readings until the IC catches up.\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 Touch Pro after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still holds the discharge curve of the degraded original cell. When the new cell hits a voltage point that mapped to \"empty\" on the old curve, the OS triggers a shutdown — even though usable charge remains. The fix is one full uninterrupted discharge down to automatic power-off, followed by a full charge with the screen off. After that cycle, the coulomb counter resets against the new cell's actual voltage-to-capacity curve and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTouch Pro not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If the voltage drops below 2.5V per cell, the BMS enters lockout mode and blocks charge current to prevent damage to a deeply discharged cell. The Touch Pro will show nothing on screen — no charging indicator, no boot. Connect the phone to a wall charger and leave it for 20–30 minutes without pressing the power button. The charge IC will trickle current into the cell at low voltage until the BMS sees a safe threshold — typically around 3.0V — and releases the lockout, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405201244250,"sku":"BWCS-HDP100XL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405201277018,"sku":"BWCS-HDP100XL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405201309786,"sku":"BWCS-HDP100XL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDP100XL-1.webp?v=1779370333","url":"https:\/\/batteryweb.com\/products\/htc-touch-pro-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
