It replaces OEM part HND-14-0019-02. These early-2000s PDAs run their RAM, contacts, calendar, and application state directly off this cell — a dead or degraded battery means data loss, not just lost power.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTreo 90, 180, and 180g compatibility:\u003c\/strong\u003e\n    All three models share the same physical footprint, connector pinout, and voltage rail. The Treo 180 and 180g added a GSM radio over the 90, but the battery spec — 3.7V, same form factor — did not change across the lineup.\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 a Treo 180 unit, confirmed the BMS accepted the charge curve without fault flags, and verified the device held full RAM state across a controlled power restoration sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSync before you swap:\u003c\/strong\u003e\n    Perform a full HotSync to your desktop before removing the battery. The Treo stores open application data and RAM state in a battery-backed volatile memory — cutting power without syncing first will wipe unsaved records and reset application state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Treo 90 loses contacts and calendar entries after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Treo 90 uses SRAM for its main data store — contacts, calendar, memos, and installed app data all live in volatile memory powered directly by the battery. The moment the cell is removed and before a new one is seated, that memory loses power and clears. Even a two-second gap is enough to wipe data that was never written to flash. The fix is a completed HotSync before removal — not after, not during reinstallation.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTreo 180g won't complete boot after new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly shipped replacement cell may arrive at 30–40% charge — below the minimum voltage the Treo's boot sequence needs to complete POST and initialise the GSM radio. The device will either freeze on the Palm logo or restart in a loop. Charge the battery to full before attempting the first boot. If the device still fails to start, hold the reset pin on the back panel for five seconds with the new cell at full charge, then power on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415954817114,"sku":"BWCS-TR180SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415954849882,"sku":"BWCS-TR180SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415954882650,"sku":"BWCS-TR180SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TR180SL-1.webp?v=1779758481","url":"https:\/\/batteryweb.com\/products\/palm-treo-90-replacement-battery-37v-650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
