Rated at 3000mAh (11.4Wh), it restores power to the processor, display, and cellular radios when the factory cell has degraded or failed outright. OEM part numbers Li3830T43P6h856337 and Li3830T430T43P6h856337 both cross to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlade S6 Lux and G719C platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions (85.00 × 62.65 × 3.60mm), the same 3.8V nominal rail, and the same connector pinout — which is why one cell covers the full range 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 charge and discharge on the Blade S6 Lux platform. The BMS accepted charge without negotiation errors, and the protection circuit tripped correctly at low-voltage cutoff without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge reset:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one complete discharge-to-charge cycle. The fuel gauge IC calibrates its coulomb counter against the new cell's discharge curve — skipping this step leaves the percentage readout inaccurate for days.\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 Blade S6 Lux after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell has a slightly different voltage-to-capacity curve than the degraded cell the fuel gauge IC was calibrated against. At 20–30% reported charge, the actual cell voltage can drop sharply under modem transmit load or screen brightness spikes — a condition called a voltage cliff. The phone's CPU reads this as an emergency shutdown condition even though the fuel gauge still shows charge remaining. Running one full discharge cycle lets the IC relearn where the real voltage cliff sits on the new cell and eliminates the false cutoff.\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-Polymer cells self-discharge during storage. If this cell sat below 2.5V before installation, the BMS may have entered a lockout state to prevent unsafe charging of an over-discharged cell. Plug the phone into a 5V charger and leave it untouched for 15–20 minutes — the charge IC trickle-charges the cell at a low current rate until voltage climbs back above the BMS re-enable threshold, typically around 2.9–3.0V. Once the BMS unlocks, normal charging resumes automatically and the boot screen appears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404159909978,"sku":"BWCS-ZTS600SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404159942746,"sku":"BWCS-ZTS600SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404159975514,"sku":"BWCS-ZTS600SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTS600SL-1.webp?v=1779369270","url":"https:\/\/batteryweb.com\/products\/zte-blade-s6-lux-dual-sim-replacement-battery-38v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
