It replaces OEM part EB-L1K6ILZ. These are CDMA-era Samsung smartphones that share the same battery bay dimensions and connector pinout across the SCH-i415 platform.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCH-i415 \/ Stratosphere II \/ Galaxy S Relay 4G platform fit:\u003c\/strong\u003e\n    These models share the same battery form factor, voltage rail, and BMS communication protocol. The EB-L1K6ILZ connector carries both power and fuel-gauge data lines, so the replacement cell must match the original footprint exactly — and this one does at 69.70 × 51.90 × 10.90mm.\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 the SCH-i415 platform. The BMS accepted charge handshake without rejection errors, and the protection circuit tripped correctly at low-voltage cutoff. No thermal anomalies were recorded during the charge cycle.\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 full discharge-to-charge cycle. The fuel gauge IC on these Samsung models is calibrated to the original cell's discharge curve. Skipping this step often causes erratic percentage readings on a new cell before the coulomb counter has re-anchored its reference points.\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 SCH-i415 after cell replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem, not a capacity problem. When the SCH-i415's modem fires during a call or the screen ramps brightness, the instantaneous current draw pulls cell voltage below the BMS protection threshold — triggering a hard cutoff even though the fuel gauge still shows charge remaining. A new cell with a mismatched internal resistance curve makes this worse in the first few cycles. Running two full discharge-charge cycles without fast charging allows the internal resistance to stabilise and the fuel gauge IC to map the actual voltage curve of the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSCH-i415 not powering on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that drop below approximately 2.5V per cell trigger a BMS lockout to prevent unsafe charging of a deeply discharged cell. The SCH-i415 will show no boot screen and no charge indicator — appearing completely dead. Connect the phone to a wall charger rated at 5V and leave it untouched for 20–30 minutes. The charge IC will trickle current into the cell at a safe low rate until voltage recovers above the BMS re-enable threshold, after which normal charging resumes. Do not attempt to force-boot during this window.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404330795098,"sku":"BWCS-SMI415XL-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404330827866,"sku":"BWCS-SMI415XL-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404330860634,"sku":"BWCS-SMI415XL-3","price":40.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI415XL-1.webp?v=1779369779","url":"https:\/\/batteryweb.com\/products\/samsung-sch-i415-replacement-battery-37v-3600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
