It cross-references OEM part numbers DIAM100, DIAM160, 35H00113-003, and 35H00113-03M. If your S900 drops charge fast, shuts down unexpectedly, or no longer holds a useful charge, this cell restores normal operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS900 compatibility:\u003c\/strong\u003e\n    The S900 uses a shared HTC Diamond-platform battery bay. The DIAM100 and DIAM160 part numbers both map to this same physical form factor and connector pinout — the BMS handshake is consistent across the platform, so this cell initialises correctly on first boot.\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 Diamond platform. The BMS accepted the cell without a protection trip, and the charge IC completed a full constant-current to constant-voltage transition without cutoff errors.\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 low battery warning, then charge uninterrupted to 100% before heavy use. Windows Mobile's fuel gauge IC is calibrated to the old cell's discharge curve — one complete cycle resets it to the new cell and stops erratic percentage readings.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the S900 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWindows Mobile uses a coulomb counter paired with a learned discharge curve from the previous cell. When you install a fresh cell, that stored curve no longer matches actual cell behaviour. The OS will show percentages that lag, jump, or freeze at values like 60% before suddenly dropping. One full discharge-charge cycle forces the fuel gauge IC to relearn the new cell's voltage-to-capacity relationship and corrects the readout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the S900 after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't recalibrated yet and the cell voltage drops below the load-sustain threshold faster than the OS expects. The S900's display, modem, and GPS together draw enough current to cause a rapid voltage sag on an uncalibrated cell. The phone interprets this sag as a dead battery and cuts power. Complete one full uninterrupted charge cycle and let the phone reach the low-battery warning naturally — after that cycle, the cutoff should shift back to below 10%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405161562202,"sku":"BWCS-HDM100HL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405161594970,"sku":"BWCS-HDM100HL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405161627738,"sku":"BWCS-HDM100HL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDM100HL-1.webp?v=1779370333","url":"https:\/\/batteryweb.com\/products\/dopod-s900-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
