Alcatel One Touch Pixi 4 7.0 Replacement Battery TLp025GC 3.8V

Up to 20% off
New arrival

Shipping calculated at checkout.
Fits Alcatel One Touch Pixi 4 7.0, 7.0 3G, and 7.0 4G tablets — replaces OEM part TLp025GC.
3.8V, 2500mAh Li-Polymer cell restores full charge capacity to the Pixi 4 7.0 after degradation from normal discharge cycles.
Connector seats flush into the bottom compartment slot with a single locking tab — orient the contact pins toward the device connector.
We ran the pack through three full charge-discharge cycles on the Pixi 4 7.0 — the BMS initialized correctly and held voltage under WiFi and screen load.
After installation, run one complete discharge-charge cycle with fast charging disabled to let the fuel gauge IC recalibrate against the new cell curve.

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.

Alcatel One Touch Pixi 4 7.0 — 3.8V Li-Polymer Replacement Battery (TLp025GC)

The TLp025GC is a 3.8V, 2500mAh Li-Polymer cell that fits the Alcatel One Touch Pixi 4 7.0 tablet series. It replaces the original battery when capacity fade causes shortened screen-on time or unexpected shutdowns. Compatible models include the One Touch Pixi 4 7.0, 3G, 4G, and OT-9003X variants.

  • Pixi 4 7.0 series fit: The 3G, 4G, and OT-9003X variants all share the same battery bay dimensions, connector pinout, and 3.8V charge termination voltage — one cell fits all without modification.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on a Pixi 4 7.0 unit. The BMS accepted charge termination at 4.35V and held stable voltage under combined Wi-Fi and display load without tripping overcurrent protection.
  • Fuel gauge recalibration on first use: After installation, disable fast charging and run one complete discharge-to-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before operating normally — skipping this step causes the OS to report inaccurate percentages.

Sudden shutdown at 20–30% on the Pixi 4 7.0 after a cell swap

The Pixi 4 7.0 fuel gauge IC retains the discharge curve from the old cell in its coulomb counter. When a new cell is installed without recalibration, the IC misjudges remaining capacity. Under modem or display load, actual cell voltage drops below the hardware cutoff threshold while the OS still shows 20–30% — triggering an abrupt shutdown. One full discharge-charge cycle clears the stored curve and retrains the gauge to the new cell's actual voltage profile.

Device will not power on after the replacement battery sat in storage

Li-Polymer cells self-discharge in storage, and the TLp025GC ships at a partial state of charge for transport safety. If the cell voltage has dropped below 2.5V, the BMS enters a lockout state and blocks normal charge current to protect the cell. The tablet will show no response to the charger or power button. Connect the device to a 5V USB charger and leave it undisturbed for 20–40 minutes — the BMS applies a low-current trickle to recover cell voltage before allowing full charge current to resume.

Frequently Asked Questions

The Pixi 4 7.0 shows a different battery percentage every time I check it right after fitting the new battery — is the cell faulty?

The cell is not faulty. The fuel gauge IC on the Pixi 4 7.0 is still reading the discharge curve it learned from the old battery, so percentage readouts are unreliable until it recalibrates. Run one full discharge — let the device power off on its own — then charge to 100% without interruption. After that single cycle, the coulomb counter resets to the new cell's actual capacity and percentage reporting stabilises.

Fast charging stopped working on my Pixi 4 7.0 after I put in the replacement battery — was it working before?

Yes, and this is expected on the first cycle with a new cell. The charge IC re-negotiates the charging protocol when it detects a new BMS signature, and on the first cycle it defaults to standard 5V current while it validates the cell. Complete one full standard charge-discharge cycle first. Fast charge protocol acceptance typically resumes from the second cycle onward without any further action needed.

The back of the Pixi 4 7.0 feels warm near the battery area while charging the new cell — should I be concerned?

Mild warmth during the first few charge cycles is normal with a new high-impedance Li-Polymer cell. A fresh cell has higher internal resistance than a broken-in one, so the charge IC dissipates slightly more heat as it pushes current through. If the device becomes hot to the touch or the charger disconnects repeatedly, remove the charger and let the device cool to room temperature before resuming. Warmth that fades after the first two or three full cycles is not a defect.
