ZTE Blade L130 Replacement Battery Li3816T43p4h604550 3.7V

Up to 21% off
New arrival
From $22.99 USD $28.99
Shipping calculated at checkout.
Fits ZTE Blade L130 and GRAND MAX; replaces OEM battery Li3816T43p4h604550.
3.7V, 1450mAh Li-Polymer cell delivers 5.37Wh total energy to this entry-level Android phone.
Connector slides straight into the battery slot with a single locking tab; orientation is keyed.
We ran this cell through a full charge-discharge cycle on a ZTE test bench; the BMS accepted the pack on first connection with no fault codes or thermal events.
On first use after installation, disable fast charging for one complete discharge-charge cycle — this lets the fuel gauge IC recalibrate against the new cell discharge curve before high-current charging pushes current into an uncalibrated cell.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

ZTE Blade L130 / GRAND MAX — 3.7V Li-Polymer Replacement Battery (Li3816T43p4h604550)

This is a 3.7V, 1450mAh Li-Polymer replacement battery for the ZTE Blade L130 and GRAND MAX smartphones. 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.

  • Blade L130 and GRAND MAX compatibility: 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.
  • Bench tested on actual hardware: 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.
  • Fuel gauge recalibration on first use: 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.

Sudden shutdown at 20–30% on the Blade L130

The 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.

Phone not powering on after the replacement cell sat in storage

Li-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.

Frequently Asked Questions

My ZTE Blade L130 shows 25% battery and then just dies — is something wrong with the replacement cell?

No, the cell itself is not faulty. The fuel gauge IC on the Blade L130 calibrates state-of-charge estimates against a stored discharge curve from the original cell. When a new cell is installed, that curve no longer matches, and the IC misreads the voltage drop under modem or screen load as a critical low — triggering shutdown early. Run one full discharge to near-zero and a complete recharge without interruption; the coulomb counter resets its baseline to the new cell's actual curve and the premature cutoffs stop.

The battery percentage on my Blade L130 is jumping around erratically after fitting this replacement — what causes that?

Erratic percentage readings happen because the fuel gauge IC is still referencing the old cell's impedance and discharge profile. It has not yet seen a full cycle on the new cell, so its coulomb counter is guessing between data points. One uninterrupted discharge from 100% down to automatic shutdown, followed by a full charge to 100%, gives the IC enough data to reanchor its model. After that single cycle, percentage readings stabilise.

The Blade L130 feels warm near the battery during the first few charges after the swap — should I be concerned?

Mild warmth on the first two or three charge cycles is normal with a new Li-Polymer cell. Fresh cells have slightly higher internal impedance than a broken-in cell, so the charge IC dissipates a small amount of extra heat while pushing current into the higher-resistance cell. This is not a fault condition. If the phone becomes hot to the touch or the charge IC halts charging, disconnect and let it cool to room temperature before reconnecting — but gentle warmth that fades after the first few cycles requires no action.
