It fits directly into the Lubi 3 battery bay and restores power to calls, messaging, and basic applications. Use this when the original cell no longer holds a charge or fails to start the phone.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLubi 3 fitment:\u003c\/strong\u003e\n    The Lubi 3 uses a compact removable cell at 53.00 x 34.00 x 4.30mm. This replacement matches that footprint exactly, so the battery door closes flush and the connector seats without force.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full discharge and charge sequences on the Lubi 3 platform. The BMS handshake completed normally each time, and charge IC communication stayed stable across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge down to auto-shutdown, then charge uninterrupted to 100% before use. This lets the Lubi 3 fuel gauge IC map the new cell's discharge curve — skipping this step causes the OS to report incorrect percentages for the first several cycles.\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 Lubi 3 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Lubi 3 fuel gauge IC stores a discharge curve from the previous cell. When a new cell arrives with a different internal resistance profile, the IC misreads remaining capacity. Under modem load — during a call or data burst — voltage drops sharply at the actual low end of the new cell, crossing the hardware cutoff threshold before the OS percentage reaches zero. One complete discharge-charge cycle after installation allows the fuel gauge to update its reference points against the new cell and resolve this behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If this battery shipped or was stored for several weeks, cell voltage may have dropped below 2.5V — the threshold where the BMS engages a protection lockout and blocks output. Connect the Lubi 3 to a charger and leave it for 15–20 minutes without pressing the power button. The charge IC will trickle current into the cell until voltage recovers above the BMS re-enable threshold, typically around 2.9V, at which point normal charging resumes and the phone will power on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405016072282,"sku":"BWCS-DEP510SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405016105050,"sku":"BWCS-DEP510SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405016137818,"sku":"BWCS-DEP510SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEP510SL_1.webp?v=1779369805","url":"https:\/\/batteryweb.com\/products\/wiko-lubi-3-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
