It fits under the OEM part numbers BLAC160, 35H00120-01M, and BA S340. Installation requires opening the rear compartment and swapping the old cell directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTouch Pro HD compatibility:\u003c\/strong\u003e\n    The Touch Pro HD uses a single Li-ion cell at 3.7V with a specific connector and BMS handshake tied to the Windows Mobile power management stack. This replacement matches that voltage rail and connector orientation so the OS recognises the battery without throwing a charge error on boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Touch Pro HD's charge IC and confirmed the BMS accepts the handshake, allows a full charge to 4.2V, and holds termination correctly at end-of-charge without false cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    On the Touch Pro HD, the fuel gauge IC retains calibration data from the old cell. After fitting this battery, run one complete discharge down to automatic shutdown, then charge uninterrupted to 100% before normal use. This resets the coulomb counter against the new cell's actual discharge curve.\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 Pro HD reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Touch Pro HD uses a fuel gauge IC that builds a discharge model from repeated charge-drain cycles on the original cell. When you install a new cell, the IC still references the old model, so reported percentage drifts from actual state of charge. This mismatch is worst in the middle of the charge range, where the old curve and new curve diverge most. One full discharge-to-shutdown followed by an uninterrupted charge to 4.2V resets the reference and corrects the readout.\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 fuel gauge IC is still running the old cell's voltage-to-capacity curve and the new cell hits its actual low-voltage cutoff earlier than the display predicts. Under modem or screen load, the cell voltage drops sharply below the BMS protection threshold — typically around 3.0V — before the OS has registered low battery. The fix is the same calibration cycle: drain to automatic shutdown, then charge fully without interruption. After two full cycles the gauge tracks the new cell accurately and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405162446938,"sku":"BWCS-HT8282XL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405162479706,"sku":"BWCS-HT8282XL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405162512474,"sku":"BWCS-HT8282XL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HT8282XL-1.webp?v=1779370332","url":"https:\/\/batteryweb.com\/products\/dopod-touch-pro-hd-replacement-battery-37v-2700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
