Both models use the same cell format — 84.15 × 49.50 × 2.70mm — with the same connector and BMS handshake requirements. Capacity is 1500mAh (5.55Wh), matching the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShine 2 HD and Shine 3 compatibility:\u003c\/strong\u003e\n    Both devices share the same cell dimensions, voltage rail, and connector pinout. The battery management system on each model expects the same charge termination voltage, so one cell covers both without any modification.\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 Shine 2 HD unit. The BMS accepted the cell without fault codes, charge termination triggered correctly at 4.2V, and the firmware reported capacity without error after a full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap charge cycle on e-readers:\u003c\/strong\u003e\n    After fitting this cell, run a full USB charge to completion before first use. The Tolino firmware reads the new cell's state-of-charge from scratch — skipping this step causes the battery percentage display to jump or read incorrectly until the calibration cycle completes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Tolino Shine 2 HD shows low battery immediately after a new cell is fitted\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eReplacement cells ship at storage voltage — typically 3.6V to 3.85V — not at full charge. The Tolino firmware checks state-of-charge on boot and reports what it finds. If the cell voltage is below the display's calibration threshold, the device shows a low battery warning even though the cell is not defective. Connect to a USB charger straight after fitting the new cell and leave it until the charge indicator clears. Do not dismiss the warning and expect normal use — the firmware needs to complete one full charge sweep to anchor its percentage readings to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePage turns slow or unresponsive after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eE-ink displays draw a short high-current pulse to refresh each page. Under low cell voltage, that pulse takes longer to execute, which shows up as a delayed or sluggish page turn. This is not a fault with the replacement cell — it is the display controller throttling refresh speed to stay within the available voltage. Charge the device fully first; page turn speed returns to normal once cell voltage is above 3.9V. If sluggishness persists after a full charge, reseat the battery connector and confirm the cell contacts are fully engaged.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360249348186,"sku":"BWCS-BNR510SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360249380954,"sku":"BWCS-BNR510SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360249413722,"sku":"BWCS-BNR510SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BNR510SL-1.webp?v=1778610980","url":"https:\/\/batteryweb.com\/products\/tolino-shine-2-hd-replacement-battery-37v-1500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
