It restores power to devices that no longer hold a charge or fail to power on. Capacity is rated at 1500mAh (5.55Wh), matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMT25 series compatibility:\u003c\/strong\u003e\n    The MT25, MT25a, and MT25i share the same battery bay dimensions, connector pinout, and charge IC handshake. Any of these three models accepts this cell 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 an MT25i unit. The BMS accepted charge current without fault flags, and the fuel gauge IC tracked state-of-charge through the full curve without interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current charging is applied to an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Xperia neo L after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still running the discharge curve from the old, degraded cell. The new cell has a steeper voltage cliff at low charge states than the worn original. When the modem fires during a call or the screen refreshes at high brightness, current draw spikes and cell voltage drops below the BMS cutoff threshold — even though the reported percentage suggests charge remains. One full discharge-charge cycle with fast charging disabled forces the IC to map the new curve and resolves the issue.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eXperia neo L not powering on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If voltage drops below 2.5V per cell, the BMS enters lockout to prevent damage and the phone will not respond to a standard power press. Connect the phone to a low-current charger — 500mA USB is enough — and leave it for 20 to 30 minutes before attempting to power on. The charge IC will trickle current into the cell until voltage clears the BMS recovery threshold, typically around 2.9V, at which point the phone boots normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409470652506,"sku":"BWCS-ERX1SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409470685274,"sku":"BWCS-ERX1SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409470718042,"sku":"BWCS-ERX1SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ERX1SL-1.webp?v=1779579784","url":"https:\/\/batteryweb.com\/products\/sony-xperia-neo-l-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
