It matches the OEM voltage and capacity spec directly from the product data. The cell uses the same connector and form factor as the factory unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP3600 and Trinity platform fitment:\u003c\/strong\u003e\n    The P3600, P3600i, Trinity, and Trinity 100 all share the same battery bay geometry, connector pinout, and 3.7V nominal voltage rail. One cell covers all four variants 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 full charge and discharge on the P3600 platform. The BMS handshake completed normally, charge termination triggered at the correct cutoff voltage, and the protection circuit responded to over-discharge conditions without tripping into lockout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installing this cell, run one complete discharge down to automatic shutoff, then charge uninterrupted to 100% before normal use. The Windows Mobile fuel gauge IC on the P3600 references a stored discharge curve — recalibrating it against the new cell prevents erratic percentage readings from the first day.\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 P3600 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Touch Diamond's processor, modem radio, and display can pull current spikes that the new cell's internal resistance cannot sustain if the fuel gauge IC is still calibrated to the old cell's discharge curve. When cell voltage drops below roughly 3.4V under load, the BMS cuts output before the OS registers a low-battery warning. This looks like a random crash but it is a voltage floor event, not a firmware or hardware fault. One full discharge-charge cycle lets the coulomb counter re-map the new cell and push the shutdown threshold to the correct point.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after sitting in storage for several months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-polymer cells self-discharge slowly in storage. If the P3600 has been unused for an extended period, cell voltage may have dropped below 2.5V — the threshold at which the BMS enters deep-discharge lockout to prevent cell damage. A standard charger will not wake it from this state because the charge IC checks for a minimum voltage before enabling current flow. Connect the phone to a USB power source and leave it for 15–20 minutes without pressing the power button; the charge IC applies a trickle recovery current that brings cell voltage back above 2.8V, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405150224474,"sku":"BWCS-DD810XL-1","price":27.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405150257242,"sku":"BWCS-DD810XL-2","price":31.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405150290010,"sku":"BWCS-DD810XL-3","price":34.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DD810XL-big.webp?v=1779370298","url":"https:\/\/batteryweb.com\/products\/htc-p3600-replacement-battery-37v-2400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
