It matches the OEM part number MP-S-O and fits the original battery compartment at 46.47 × 39.79 × 5.33mm. Install it when the original cell no longer holds a usable charge between top-ups.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e9025 TV and 9025TV Moon compatibility:\u003c\/strong\u003e\n    These variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell fits all four listed models without 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 the 9025 platform and confirmed the BMS accepted the new cell without triggering a fault state. Cutoff voltage held correctly at the low end, and the charge IC reached full termination without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    Disable fast charging for one full discharge-charge cycle after installation. The fuel gauge IC was calibrated to your old cell's discharge curve. Running one complete slow cycle gives the coulomb counter a clean reference before high-current charging is applied to the new cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 9025 TV reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the 9025 platform tracks charge state using a coulomb counter calibrated against the original cell's discharge curve. When a new cell goes in, that stored curve no longer matches the actual cell chemistry. The IC reports stale data until it re-learns the new cell's behaviour. One full slow discharge down to automatic shutdown, followed by a complete charge to 100%, resets the calibration and brings percentage reporting back in line.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops sharply under load — typically during screen-on peaks or active data use — before the fuel gauge reaches its low-battery warning threshold. The phone shuts down because the cell cannot sustain the voltage rail, even though the reported percentage looks safe. It is not a faulty battery; it is the fuel gauge IC still using the old cell's curve to estimate remaining charge. Complete one full slow discharge-charge cycle and the shutdowns will stop as the counter recalibrates to the new cell's actual voltage cliff point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409483694170,"sku":"BWCS-NK5FSL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409483726938,"sku":"BWCS-NK5FSL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409483759706,"sku":"BWCS-NK5FSL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK5FSL-1.webp?v=1779579814","url":"https:\/\/batteryweb.com\/products\/myphone-9025-tv-replacement-battery-37v-950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
