LG 510 CDMA Replacement Battery LGLI-AAEL 3.7V 1150mAh

Replaces LGLI-AAEL battery for LG 510 (CDMA) and TP1100 smartphone models.
This cell delivers 3.7V at 1150mAh — sufficient capacity for calling and messaging on the 510 platform without extended runtime between charges.
Connector slides into the original battery slot with standard orientation; locking tab engages flush against the phone housing.
We bench-tested the BMS against the 510's fuel gauge IC; voltage held steady under modem load with no early cutoff signals.
On first use after installation, disable fast charging for one complete discharge-charge cycle so the coulomb counter recalibrates against this cell's discharge curve before high-current charging resumes.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

LG 510 (CDMA) Series — 3.7V Li-ion Replacement Battery (LGLI-AAEL)

This is a 3.7V, 1150mAh Li-ion replacement battery for the LG 510 (CDMA), Touch Point, TP1100, and related models. It replaces OEM part number LGLI-AAEL. Fit the cell when the original no longer holds a charge or causes random shutdowns.

  • 510 (CDMA) and Touch Point compatibility: These models share the same battery footprint, connector pinout, and voltage rail. The BMS handshake spec is identical across the 510 CDMA and TP1100 variants, so one cell covers the whole group without any wiring changes.
  • Bench tested on actual hardware: We cycled this cell through charge, standby, and active call load on a 510-series unit. The BMS held cutoff correctly at both low-voltage and overvoltage thresholds, and the fuel gauge IC tracked state-of-charge without resetting mid-cycle.
  • Fuel gauge recalibration on first use: On first installation, disable any fast-charge option and run one complete discharge-charge cycle before normal use. This lets the fuel gauge IC build an accurate discharge curve against the new cell before high-current charging pushes current into an uncalibrated coulomb counter.

Why the LG 510 reports wrong battery percentage after a cell swap

The fuel gauge IC on the 510 stores a discharge curve calibrated to the original cell's impedance profile. A new cell has a different internal resistance, so the IC maps voltage readings against the wrong curve. This causes the percentage display to read high or low by 10–20 points until recalibration. One full discharge to automatic cutoff followed by an uninterrupted charge to 100% resets the stored curve to match the replacement cell.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops below the modem or display load threshold faster than the fuel gauge expects — a classic voltage cliff on a new cell that hasn't been calibrated yet. The BMS trips the cutoff before the displayed percentage reaches zero because the voltage sags sharply under GSM transmit bursts or screen-on load. It is not a faulty cell. Run one full discharge cycle without interruption, let the phone reach automatic shutdown, then charge fully to 4.2V. The cliff behaviour resolves once the fuel gauge IC has a complete curve to reference.

Frequently Asked Questions

The phone powered on fine after I put in the new battery, but now it shuts off suddenly at around 25% — is the cell bad?

The cell is almost certainly fine. A fresh Li-ion cell has a steeper voltage cliff than a broken-in one, and the fuel gauge IC is still using the discharge curve it learned from the old battery. Under modem transmit load, voltage sags past the BMS cutoff threshold before the displayed percentage catches up. Run one uninterrupted full discharge to automatic shutdown, then charge to 100% — after that single cycle the IC recalibrates and the shutdowns stop.

The LG 510 won't turn on at all after the replacement battery sat in a drawer for a few months before I installed it — is it dead?

Probably not. Li-ion cells self-discharge in storage, and if this one dropped below roughly 2.5V per cell the BMS will have entered lockout mode to prevent damage. A standard charger won't wake it because the BMS blocks current at that voltage. Connect the phone to a wall charger — not USB from a PC — and leave it for 20–30 minutes without pressing the power button. The charge IC trickle-feeds current below the BMS threshold to bring the cell back to 3.0V, at which point the BMS releases and normal charging begins.

Battery percentage jumps around erratically — for example it reads 60%, then skips to 45%, then back to 55% within a few minutes of use — what's causing that?

The coulomb counter inside the fuel gauge IC is recalibrating against the new cell's discharge curve and hasn't settled yet. This is most obvious in the first two or three charge cycles after a cell replacement because the IC is interpolating between data points it built for the original battery. Each full discharge-charge cycle gives the IC more accurate reference points. After two complete cycles the percentage readings stabilise — if they don't, check that the battery connector is fully seated, since a loose pin causes voltage noise that looks identical to a drifting coulomb counter.
