It slots directly into place of the original ELF0160 cell. Voltage and connector match the original charge IC exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTouch, S1, S500, and S505 share this cell:\u003c\/strong\u003e\n    All four models run the same 3.7V battery architecture with identical connector pinout and BMS handshake protocol — one cell covers the entire line 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 charge and discharge on the Touch platform. The BMS accepted the cell without fault codes, and the charge IC stepped through trickle, bulk, and termination phases cleanly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to around 5–10% before recharging completely. The Windows Mobile fuel gauge IC on the Touch series reads coulombs against the old cell's internal resistance profile — one full cycle resets that baseline against the new cell.\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 Dopod Touch after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Touch's fuel gauge IC builds a discharge curve from the previous cell's internal resistance. When a new cell goes in, the IC is still reading that old curve. At around 20–30% reported charge, the new cell's actual voltage hasn't dropped that low — but the IC thinks it has and triggers a shutdown. One complete discharge-charge cycle forces the coulomb counter to recalibrate its endpoint against the new cell. After that cycle, shutdowns at false-low percentages stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDopod Touch won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage, and if the voltage drops below 2.5V per cell, the BMS trips into lockout to prevent further discharge damage. The phone shows nothing — no charging animation, no boot screen. Connect the device to a wall charger (not a USB port) and leave it for 20–30 minutes without pressing any buttons. The charge IC delivers a low trickle current that slowly lifts the cell above the BMS re-enable threshold, typically around 2.9–3.0V, at which point the BMS unlocks and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405253935194,"sku":"BWCS-DTS1SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405253967962,"sku":"BWCS-DTS1SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405254000730,"sku":"BWCS-DTS1SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DTS1SL-1.webp?v=1779370350","url":"https:\/\/batteryweb.com\/products\/dopod-touch-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
