It replaces OEM part numbers JADE160, 35H00118-00M, and BA S330. Physical dimensions are 51.76 × 37.14 × 10.83mm — confirm these against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTouch 3G and Jade platform fit:\u003c\/strong\u003e\n    The Touch 3G and Jade share the same battery bay geometry and connector pinout across all variants. Voltage rail is identical at 3.7V nominal, and the BMS handshake uses the same thermistor pin arrangement, so one cell covers all four listed models.\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 a Touch 3G unit. The BMS accepted charge current without fault, protection circuitry triggered correctly at low-voltage cutoff, and the fuel gauge IC began tracking cell state within the first complete cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable any fast-charge accessory and run one full discharge-to-charge cycle at standard current. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve before high-current charging introduces uncalibrated offsets.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Touch 3G reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the Touch 3G stores a learned discharge curve from the previous cell. When a new cell goes in, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. The OS reads fuel gauge register values built for a degraded old cell and displays percentages that don't reflect real charge state. One complete discharge down to automatic cutoff, followed by a full charge to 4.2V, resets the coulomb counter and aligns the gauge to the new cell.\u003c\/p\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 3G radio or backlight pulls a current spike the cell cannot sustain at that state of charge — voltage drops sharply below the BMS cutoff threshold even though the fuel gauge still shows charge remaining. The fuel gauge IC is reading a stale curve and misjudging how much headroom the cell actually has. Run the device through two full calibration cycles to synchronise the gauge. If shutdown still occurs below 3.6V under load, check that the battery contacts are clean and making full contact with the bay terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405161365594,"sku":"BWCS-DTS3XL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405161398362,"sku":"BWCS-DTS3XL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405161431130,"sku":"BWCS-DTS3XL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DTS3XL-1.webp?v=1779370333","url":"https:\/\/batteryweb.com\/products\/htc-touch-3g-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
