The Pocket Web is a small-form-factor smartphone, and this cell matches its voltage rail and physical form factor. Capacity figure is sourced from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOGO Pocket Web fitment:\u003c\/strong\u003e\n    The Pocket Web runs a single-cell 3.7V Li-ion architecture. This replacement matches that voltage rail directly. The BMS on the Pocket Web manages charge cutoff and low-voltage protection — this cell is compatible with that charge management circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full discharge and charge sequence on the bench. The BMS accepted charge without triggering early cutoff, and the protection circuit responded correctly at low-voltage threshold. No thermal event occurred during the charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installing this cell, disable fast charging and run one complete discharge down to automatic shutoff, then charge uninterrupted to 100%. This gives the Pocket Web's fuel gauge IC a clean reference point against the new cell's discharge curve before any high-current charging runs.\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 OGO Pocket Web after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-ion cell has a slightly different discharge curve than the aged cell the fuel gauge IC was calibrated against. When screen brightness or mobile data pulls current hard, the new cell's voltage can dip below the BMS protection floor before the OS percentage reading catches up. The phone shuts down even though the gauge still shows charge remaining. One full discharge-charge cycle without interruption resets the coulomb counter and eliminates most of these early cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOGO Pocket Web not powering on after sitting in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the cell voltage drops below approximately 2.5V per cell, the BMS locks out to prevent damage — the phone will not respond to the power button and may show no charge indicator even on a cable. Connect the Pocket Web to a wall charger (not a PC USB port, which may not supply enough current) and leave it for at least 20–30 minutes before attempting to power on. If the BMS recovers, the charge indicator will appear. If it does not appear after an hour on a wall charger, the cell has dropped below recoverable threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409509384282,"sku":"BWCS-MPX200SL-1","price":23.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409509417050,"sku":"BWCS-MPX200SL-2","price":27.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409509449818,"sku":"BWCS-MPX200SL-3","price":29.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MPX200SL-big.webp?v=1779579871","url":"https:\/\/batteryweb.com\/products\/ogo-pocket-web-replacement-battery-37v-750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
