It fits the P6's compact battery bay and connects to the same BMS interface as the factory cell. Capacity figure is taken directly from the product specification — 1600mAh \/ 5.92Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBoyue P6 fitment:\u003c\/strong\u003e\n    The P6 uses a single-cell Li-Polymer pack at 3.7V nominal. The flat pouch format at 69.20 × 57.22 × 3.60mm matches the original cell cavity, and the connector pinout mirrors the factory BMS handshake so the e-reader firmware reads charge state normally.\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 the P6 platform. The BMS accepted the new cell without fault codes, and battery percentage reported correctly after a full charge cycle was completed from storage voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap charge cycle on the P6:\u003c\/strong\u003e\n    After fitting this cell, connect via USB to a charger and run one complete charge cycle before use. The P6 firmware recalibrates its battery percentage display to the new cell during that first full charge — skipping it causes the indicator to read inaccurately for several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the P6 shows an incorrect battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eE-reader firmware tracks charge state against a learned cell profile built up over many cycles. When a new cell goes in at storage voltage — typically around 3.6–3.7V — the firmware has no calibration data for it yet. The percentage display maps against the old profile, so it can show values like 60% on a fully charged cell or drop suddenly mid-session. One complete charge-to-full cycle rewrites the reference point and the display stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eP6 not powering on after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the P6 shows nothing after a swap, the replacement cell has likely shipped at a voltage below the device's minimum boot threshold — typically under 3.4V. The unit will not attempt to power on below this level as a low-voltage protection measure in the BMS. Connect the P6 to a USB charger and leave it for 10 minutes without pressing the power button. Once the cell climbs above the boot threshold, the device will respond normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360242335834,"sku":"BWCS-BYP600SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360242368602,"sku":"BWCS-BYP600SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360242401370,"sku":"BWCS-BYP600SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BYP600SL-1.webp?v=1778610982","url":"https:\/\/batteryweb.com\/products\/boyue-p6-replacement-battery-37v-1600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
