It also fits the Stratosphere 4G and Stratosphere 4G LTE variants. Voltage and footprint match the original Samsung-sourced cell at 64.40 × 50.90 × 5.00mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStratosphere i405 and SCH-i405 compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, 3.7V nominal rail, and EB505165YZ connector pinout — so the same cell covers the full Stratosphere lineup without modification.\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 load discharge on the Stratosphere platform. The BMS accepted charge handshake without fault codes, and voltage held stable across display and modem draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve before drawing high current into 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 Stratosphere i405\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity problem. Under combined modem and display load, cell voltage drops faster than the fuel gauge IC predicts — the phone shuts off before the reported percentage reaches zero. It happens most on fresh cells where the coulomb counter is still calibrated to the old, degraded cell curve. One full discharge-charge cycle with the screen on normalises the IC's curve. After that cycle, shutdowns below 20% should stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If voltage drops below 2.5V per cell, the BMS trips a lockout to prevent damage and the phone will not respond to the power button. Connect to a wall charger — not a PC USB port — and leave it for 15–20 minutes without pressing anything. The charge IC needs to trickle current past the lockout threshold before the BMS re-initialises and allows normal boot. Once the charging indicator appears on screen, the BMS has cleared.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405052215386,"sku":"BWCS-SMI405SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405052248154,"sku":"BWCS-SMI405SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405052280922,"sku":"BWCS-SMI405SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI405SL-1.webp?v=1779369899","url":"https:\/\/batteryweb.com\/products\/verizon-stratosphere-i405-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
