It fits the SM-W2018, SM-W2018 World Flagship, and SM-W2018 World Flagship 2018 Dual SIM. Capacity and voltage match the original spec exactly — no modifications needed for installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-W2018 flip chassis compatibility:\u003c\/strong\u003e\n    All SM-W2018 variants share the same battery bay dimensions and connector orientation. The 71.55 × 33.25 × 5.50mm cell profile fits the flip housing without pressure on the internal flex cables.\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 an SM-W2018 unit. The BMS accepted charge current correctly, and the fuel gauge IC registered capacity without faults across both screens and the modem stack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\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 against the new cell's discharge curve before high-current charging pushes current into an uncalibrated state.\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 SM-W2018 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SM-W2018 runs two displays and an active modem simultaneously — load spikes are frequent and sharp. A new cell with an uncalibrated fuel gauge IC can report 25% remaining while actual terminal voltage has already dropped below the shutdown threshold. The phone's PMIC interprets the voltage cliff as a fault and cuts power before the OS can log a low-battery warning. One full discharge-to-shutdown followed by an uninterrupted charge to 100% resets the coulomb counter and resolves this.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells shipped in partial charge can self-discharge below 2.5V per cell during extended storage. Below that threshold, the BMS enters lockout to prevent cell damage and blocks all charge current — the phone shows nothing when connected to a charger. Connect the device to a 5V USB source for 15–20 minutes without attempting to power it on; the trickle path in the charge IC slowly recovers cell voltage until the BMS exits lockout. Once the screen shows the charging indicator, proceed with a normal charge cycle to 100%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392001245274,"sku":"BWCS-SMW018SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392001278042,"sku":"BWCS-SMW018SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392001310810,"sku":"BWCS-SMW018SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMW018SL-1.webp?v=1779142875","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-golden-5-replacement-battery-385v-2200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
