It fits the pocket PC form factor used for mobile computing, scheduling, and navigation. Swap it in to restore full operation on a device where the original cell has degraded or failed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePDA 255 and PXA 255 platform:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, 3.7V voltage rail, and connector pinout — one cell covers the pair. The BMS handshake is identical across both variants, so the charge circuit accepts this replacement without reconfiguration.\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 PDA 255 unit. The BMS accepted full charge without fault codes, and the device booted cleanly from a cold start at the first attempt.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRAM data protection before swap:\u003c\/strong\u003e\n    The PDA 255 holds open files, contacts, and application state in SRAM powered directly by the main battery. Sync all data to the host PC before removing the old cell — cutting power without syncing will wipe anything not written to flash storage.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the PDA 255 refuses to boot after a new battery is fitted\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PDA 255 boot sequence checks for a minimum voltage threshold before the processor initialises. A new cell shipped in storage state may sit below that threshold, even though the battery is not faulty. The device will show nothing on screen or loop on the splash screen until the cell reaches sufficient charge. Connect the PDA to its charger for at least 30 minutes before attempting the first power-on.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery life noticeably shorter when using wireless sync or GPS\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe wireless radio and GPS receiver on the PDA 255 draw significantly more current than standby or basic scheduling tasks. This voltage sag under radio load can trigger the BMS to report a lower state of charge than the cell actually holds. If battery life drops sharply during active sync sessions, verify the cell is at full charge before starting a wireless transfer, and close background applications to reduce concurrent draw on the 3.7V rail.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415948034138,"sku":"BWCS-MIO168SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415948066906,"sku":"BWCS-MIO168SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415948099674,"sku":"BWCS-MIO168SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MIO168SL-1.webp?v=1779758396","url":"https:\/\/batteryweb.com\/products\/bluemedia-pda-255-replacement-battery-37v-1300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
