It replaces the original battery when capacity has dropped or the cell no longer holds a charge through normal daily use. Dimensions are 70.25 × 60.00 × 5.05mm — verify these against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExplay Fresh fit:\u003c\/strong\u003e\n    The Fresh uses a compact unibody-style chassis with a fixed battery bay. This cell matches the connector pinout and physical footprint of the factory unit, so no adapter or modification is needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on this cell and confirmed the BMS communicates correctly with the phone's charge IC. Charge termination triggered at the correct voltage and the protection circuit tripped as expected under overcurrent conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-to-charge cycle. This gives the phone's fuel gauge IC time to map the new cell's discharge curve before high-current charging begins on 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 Explay Fresh after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC on the Fresh is still calibrated to the old cell's discharge curve. When the new cell hits a voltage the IC hasn't mapped yet, the phone reads the drop as critical and shuts down — even though charge remains. The fix is one full discharge-to-charge cycle without interruption. After that cycle, the coulomb counter resets against the new cell's actual curve and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS reporting erratic or jumping battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePercentage jumps — such as dropping from 45% to 12% in seconds — point to the fuel gauge IC recalibrating against an unfamiliar cell. The IC uses stored data from the previous cell and the mismatch causes unstable readings. Let the phone discharge to auto-shutdown, then charge uninterrupted to 100% with the screen off. After one clean cycle, the percentage should stabilise.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404279414874,"sku":"BWCS-BLD530SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404279447642,"sku":"BWCS-BLD530SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404279480410,"sku":"BWCS-BLD530SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLD530SL-1.webp?v=1779369550","url":"https:\/\/batteryweb.com\/products\/explay-fresh-replacement-battery-37v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
