It replaces OEM part Li3816T43p4h604550 directly. Swap it in when the original cell no longer holds a useful charge or the phone shuts off unexpectedly under load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlade L130 and GRAND MAX compatibility:\u003c\/strong\u003e\n    Both models share the same 3.7V battery bay, connector pinout, and BMS handshake protocol — one cell fits both. The Li3816T43p4h604550 part number covers the full production run of each device.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Blade L130 unit. The BMS accepted the cell without fault codes, and charge IC communication stayed normal across the full voltage window from 3.0V to 4.2V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, run one complete discharge-charge cycle with fast charging disabled. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging begins on an uncalibrated coulomb counter.\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 L130\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Blade L130 uses a simple fuel gauge IC that reads cell voltage and estimates state of charge from a stored curve. When an aged or deeply discharged cell cannot sustain voltage under modem transmit or screen backlight load, the IC sees a voltage cliff and the phone cuts off — even though the displayed percentage looks safe. A new cell with lower internal resistance holds voltage under the same load, eliminating the premature cutoff. After fitting this replacement, run one full discharge to near-zero before recharging to let the IC re-anchor its curve to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells that have self-discharged below approximately 2.5V trigger BMS lockout — the protection circuit opens and blocks current flow to prevent cell damage. The phone will not respond to the power button and may show no charge indicator when connected to USB. Connect the phone to a wall adapter rather than a PC port, which delivers a full 5V at sufficient current to wake the BMS trickle-charge circuit. Leave it connected for 20–30 minutes before attempting to power on; once cell voltage recovers above 3.0V, the BMS closes and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391791071322,"sku":"BWCS-ZTL130SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391791104090,"sku":"BWCS-ZTL130SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391791136858,"sku":"BWCS-ZTL130SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTL130SL-1.webp?v=1779142051","url":"https:\/\/batteryweb.com\/products\/zte-blade-l130-replacement-battery-37v-1450mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
