It matches the original cell's flat-pack form factor at 49.92 × 34.28 × 4.93mm, so it fits the internal cavity without modification. Capacity is drawn from the product specification, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSA6015 and SA6025 shared battery platform:\u003c\/strong\u003e\n    Both models use the same flat Li-Polymer cell voltage rail and connector pinout. Philips carried the same battery footprint across these GoGear variants, so one cell covers the full group without adapter wiring or connector swaps.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the SA6025 platform. The BMS accepted the cell without triggering a fault, stepped through each charge phase correctly, and held the cut-off voltage at the expected 4.2V ceiling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install first charge on GoGear players:\u003c\/strong\u003e\n    If the player sat unused for months before the swap, connect it to the USB charger immediately after installing the new cell and leave it for a full uninterrupted charge cycle. GoGear units can enter a low-voltage protection state that blocks normal boot until the cell climbs past the minimum threshold from a slow trickle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGoGear SA6025 battery percentage jumping after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter fitting a new Li-Polymer cell, the on-screen battery indicator often skips — showing 80%, then 60%, then 95% across short playback windows. This is normal. The GoGear firmware tracks battery level using voltage thresholds calibrated to the original cell's discharge curve, and a fresh cell's curve sits slightly outside those stored reference points. Run two or three full charge-to-drain cycles and the indicator stabilises as the firmware re-maps to the new cell's actual voltage behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePlayback cutting out before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens at the tail end of a degraded cell's discharge curve. The audio amplifier inside the SA6015 draws a short burst of current to drive the headphone output, and an ageing cell can't hold voltage steady under that brief spike. The BMS reads the voltage dip as a low-cell event and shuts the device down even though the displayed percentage hasn't hit zero. Fitting a fresh 800mAh cell restores the voltage buffer that keeps the amplifier stable through that final discharge window.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381342371930,"sku":"BWCS-PS025SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381342404698,"sku":"BWCS-PS025SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381342437466,"sku":"BWCS-PS025SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PS025SL_1.webp?v=1778900059","url":"https:\/\/batteryweb.com\/products\/philips-gogear-sa6015-replacement-battery-37v-800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
