It matches the OEM part numbers 019387 and C71B. Capacity is sourced from the product specification — 2800mAh (10.36Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePogo Tech C71B\/019387 platform:\u003c\/strong\u003e\n    These part numbers reference the same battery line — same voltage rail, same connector pinout, same BMS handshake protocol. Either reference number confirms fitment on the Pogo Tech media player.\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 Pogo Tech unit. The BMS accepted charge current normally, held the voltage rail steady through audio and video playback, and tripped the low-voltage cutoff at the expected threshold without sudden shutdown.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle:\u003c\/strong\u003e\n    If the player arrives from storage without turning on, connect the charger and leave it for 30 minutes before pressing the power button. Media players with depleted cells enter a deep-discharge protection state where the BMS blocks normal operation until a slow trickle charge brings the cell voltage above the recovery threshold.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping after cell swap on the Pogo Tech\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAfter fitting a new cell, the Pogo Tech's fuel gauge reads from the voltage curve it stored for the old battery — not the new one. The indicator may jump from 80% to 20% or skip numbers mid-playback. This is a voltage-threshold recalibration issue, not a fault with the replacement cell. Run the battery down fully until the device powers off, then charge it to 100% uninterrupted. One complete cycle resets the fuel gauge to the correct voltage reference points.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePlayback cutting out before the battery indicator shows empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe audio amplifier inside the Pogo Tech draws a spike of current each time it drives the speaker or headphone output. Near the end of a discharge cycle, cell voltage sags under that load even when the battery meter still shows a remaining charge. The BMS reads the voltage drop as a cutoff event and shuts the device down. If this happens consistently, run one full charge-discharge cycle — a fully conditioned cell holds voltage more steadily under load and delays that sag point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381340897370,"sku":"BWCS-PG01SL-1","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43381340930138,"sku":"BWCS-PG01SL-2","price":30.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43381340962906,"sku":"BWCS-PG01SL-3","price":33.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PG01SL-1.webp?v=1778900059","url":"https:\/\/batteryweb.com\/products\/pogo-tech-replacement-battery-37v-2800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
