It fits the original battery bay and connects to the same internal contacts. Use the capacity from the product data: 2000mAh at 7.4Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTreo 600 and 610 shared platform:\u003c\/strong\u003e\n    Both models run the same battery bay dimensions, voltage rail, and connector pinout. The 610 is a regional carrier variant of the 600 with no electrical differences at the battery interface — the same cell services both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the cell through the Treo 600's charge IC and confirmed the BMS communicates correctly across a full charge cycle. Charge acceptance was normal and no overcurrent trips were triggered during the initial load test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    On first use, disable any fast-charge accessory and run one complete discharge-to-charge cycle before normal use. This allows the fuel gauge IC to map the new cell's discharge curve before the charge IC pushes higher current into an uncalibrated 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 Treo 600 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue. Under GSM modem load or backlight spikes, the cell voltage drops faster than the fuel gauge IC expects based on the old cell's curve. The phone reads 25% remaining but the actual cell voltage falls below the shutdown threshold. One full discharge and recharge cycle lets the coulomb counter recalibrate against the new cell. After that cycle, the reported percentage tracks actual capacity accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTreo 600 not powering on after sitting in storage with a flat battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf a Li-ion cell discharges below approximately 2.5V during extended storage, the BMS enters lockout to prevent a damaged cell from accepting charge current. The Treo 600's charge IC will not begin a normal charge cycle from this state. Connect the device to a wall charger — not a USB port — and leave it for 20–30 minutes without pressing the power button. The charge IC uses a trickle pre-charge mode to bring the cell back above the BMS re-enable threshold, typically around 2.9V, before switching to standard charge current.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409503223898,"sku":"BWCS-TR600SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409503256666,"sku":"BWCS-TR600SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409503289434,"sku":"BWCS-TR600SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TR600SL-1.webp?v=1779579830","url":"https:\/\/batteryweb.com\/products\/palm-treo-600-replacement-battery-37v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
