It replaces OEM part numbers EB454357VU and EB454357VA. The battery slots directly into the standard Galaxy Y battery bay and connects to the existing charging circuit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-S5360 and S5380 series fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and 3.7V nominal voltage rail. The BMS handshake protocol is identical across the group, so one cell serves the full compatibility list without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a GT-S5360 unit and monitored the BMS across charge and discharge. The protection circuit held cutoff at 4.2V on charge and engaged undervoltage lockout cleanly below 3.0V with no false trips under screen and modem load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to automatic shutdown followed by an uninterrupted charge to 100% before normal use. The GT-S5360 uses a basic coulomb counter — skipping this cycle leaves the fuel gauge reading against the old cell's curve, which causes jumpy or inaccurate percentages.\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 GT-S5360 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity fault. Under combined screen brightness and GSM modem load, the new cell's internal resistance causes a brief voltage drop that the fuel gauge misreads as a critical low-battery event — triggering shutdown even though charge remains. The Galaxy Y's power management IC is tuned to the discharge curve of an aged original cell, so a fresh high-capacity replacement cell can confuse it early in its life. One full discharge-charge calibration cycle resolves this in most cases by re-anchoring the coulomb counter to the new cell's actual voltage curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGT-S5360 not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that sit uncharged for several weeks can drop below 2.5V per cell, triggering BMS lockout — the protection circuit disconnects the cell entirely to prevent damage. The phone will show nothing when you press the power button, and plugging in a charger may produce no response for several minutes. Connect the phone to a wall charger (not USB-PC) and leave it for 20–30 minutes without interruption — the charge IC will trickle current into the cell until voltage rises above the BMS recovery threshold, typically around 2.9V. Once the charging indicator appears on screen, the BMS has re-initialised and normal charging will resume.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405065355354,"sku":"BWCS-SM5360SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405065388122,"sku":"BWCS-SM5360SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405065420890,"sku":"BWCS-SM5360SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SM5360SL-1.webp?v=1779369898","url":"https:\/\/batteryweb.com\/products\/samsung-gt-s5360-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
