It fits the e700, e740, e750, and e750 Wifi handheld PDAs — Windows Mobile devices used for email, contacts, calendar, and third-party applications. Voltage and capacity match the original spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ee700 \/ e740 \/ e750 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol across the series. A single cell covers all variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the e750 charge controller and confirmed the BMS accepted the cell, balanced correctly, and held voltage across a full discharge cycle without premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRAM retention before swap:\u003c\/strong\u003e\n    Sync all open data to a host computer before removing the old battery. The e700 series stores active application state and unsaved files in volatile SRAM powered directly by the main cell — a full power loss clears that memory entirely.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the e700 loses all open data when the battery is removed\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe e700 series has no internal flash buffer for application state. Open files, calendar entries, and app data live in SRAM, which requires continuous battery power to retain its contents. The moment main battery voltage drops to zero during a swap, that memory is erased. A backup capacitor on some units buys seconds — not enough for a cold swap without prior sync. Always perform a full ActiveSync or Windows Mobile Device Center sync before pulling the cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ee700 stuck on black screen after new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed replacement cell may have shipped at a low state of charge — sometimes below the 3.3V minimum the boot ROM requires to initialise hardware. The device will show nothing on screen and appear dead. Connect it to the OEM charger or a compatible 5V USB cradle for at least 20 minutes before pressing the power button. If the screen still does not respond after charging, perform a hard reset using the recessed reset pin on the underside of the unit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415954325594,"sku":"BWCS-E700SL-1","price":34.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43415954358362,"sku":"BWCS-E700SL-2","price":39.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43415954391130,"sku":"BWCS-E700SL-3","price":43.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-E700SL-big.webp?v=1779758425","url":"https:\/\/batteryweb.com\/products\/toshiba-e700-replacement-battery-37v-1200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
