It fits the YP-T8 directly and matches the original connector and footprint. Capacity figures are taken from our product data: 800mAh \/ 2.96Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYP-T8 fit:\u003c\/strong\u003e\n    The YP-T8 uses a single-cell 3.7V Li-ion pack with a compact form factor — 42.66 × 30.79 × 4.59mm. That specific cell size and the BMS handshake are why this battery works in the YP-T8 and not in adjacent Samsung media player models with different connector pinouts.\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 YP-T8 platform. The BMS accepted full charge current without triggering protection cutoff, and the board read the cell voltage correctly through the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap charge protocol for the YP-T8:\u003c\/strong\u003e\n    Media players like the YP-T8 often enter deep discharge protection state after long storage. Connect the charger immediately after installing and leave it for at least 30 minutes before attempting to power on — the device needs a slow trickle charge before it will accept normal charge current.\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 a cell swap on the YP-T8\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter fitting a new Li-ion cell, the YP-T8's fuel gauge reads from voltage thresholds baked into the original firmware calibration. A fresh cell has a slightly different discharge curve than a worn original, so the percentage display recalibrates over the first few cycles. You may see the indicator jump from 80% to 40% without warning during early use. Run two or three full charge-to-discharge cycles and the readings will stabilise — the cell itself is not faulty.\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 in the YP-T8 draws a brief current spike when driving output at higher volumes. Near the end of the discharge curve — typically below 3.5V — the cell can no longer sustain that spike without voltage sagging below the amplifier's minimum rail. The player cuts out or reboots even though the gauge still shows a few percent remaining. This is a voltage-sag issue, not a capacity issue. Lower the playback volume at the end of a charge cycle and the player will reach true cut-off before dropping out.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381343387738,"sku":"BWCS-SMT8SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381343420506,"sku":"BWCS-SMT8SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381343453274,"sku":"BWCS-SMT8SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMT8SL-1.webp?v=1778900081","url":"https:\/\/batteryweb.com\/products\/samsung-yp-t8-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
