It replaces OEM part number 07-016006345. The MobilePro P300 is an early-2000s Pocket PC device used for mobile data entry, field computing, and legacy workflow applications.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMobilePro P300 fit:\u003c\/strong\u003e\n    The P300 uses a slim, single-cell lithium-ion pack at 3.7V to power its ARM-based processor, display backlight, and onboard RAM. This cell matches the OEM voltage rail and connector so the device's power management firmware accepts it without error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a MobilePro P300 unit. The BMS held cutoff correctly at low voltage and accepted a standard 4.2V charge ceiling without triggering any protection flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRAM data protection before swap:\u003c\/strong\u003e\n    The MobilePro P300 stores open files and application state in volatile SRAM powered directly by the main battery. Perform a full data sync to the host PC before removing the old battery — once the cell drops below the SRAM hold threshold, unsaved data in RAM is gone permanently.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MobilePro P300 won't boot after a new battery is installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe P300's boot sequence requires a minimum voltage before the processor will start. A new battery shipped in storage state may sit at 3.0V or lower — below that threshold, the device shows nothing on screen or flickers and dies immediately. This is not a faulty battery or a faulty device. Connect the P300 to its charger for at least 30 minutes before attempting to power it on, giving the cell enough charge to cross the boot minimum voltage before you press the power button.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eP300 battery gauge reading full but device cuts out under load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn aged or deeply discharged lithium cells, the P300's onboard fuel gauge can misread state of charge — it reports full while the cell's actual capacity has dropped enough that any display or backlight load causes an immediate voltage sag and shutdown. This is a cell aging problem, not a firmware bug. A replacement cell at full 4.2V charge will hold the voltage rail steady under normal display and processor load. After fitting this battery, run one complete charge cycle before trusting the gauge reading.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415944527962,"sku":"BWCS-P300SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415944560730,"sku":"BWCS-P300SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415944593498,"sku":"BWCS-P300SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P300SL-1.webp?v=1779758397","url":"https:\/\/batteryweb.com\/products\/nec-mobilepro-p300-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
