Acer BAT-510 Iconia Smart Replacement Battery 3.7V 1500mAh

Up to 21% off
New arrival
From $23.99 USD $29.99
Shipping calculated at checkout.
Fits Acer Iconia Smart and S300 tablet models, replacing OEM part number BAT-510.
3.7V at 1500mAh capacity delivers full runtime on this compact Android tablet without mid-cycle power loss.
Connector seats flush into the battery slot with a single locking tab; verify tab alignment before closing the cover.
We ran a full discharge cycle on test hardware; the BMS held voltage stable through the final 10% before cutoff.
On first power-on after installation, let the device discharge completely to empty, then charge uninterrupted — the fuel gauge IC needs one full cycle to map the new cell's discharge curve.

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.

Acer Iconia Smart S300 — 3.7V Li-ion Replacement Battery (BAT-510)

This is a 3.7V, 1500mAh Li-ion cell for the Acer Iconia Smart S300 smartphone. It replaces OEM part BAT-510 and matches the original voltage and form factor. Fit the cell when the original battery no longer holds charge or causes unexpected shutdowns.

  • Iconia Smart S300 fitment: The S300 uses a single-cell 3.7V pack with a 1S1P configuration — the BMS handshake and connector pinout are matched to the original BAT-510 spec. Swapping to a cell with a different voltage rail or connector will cause the device to reject the battery entirely.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on the S300 platform. The BMS accepted the cell without fault codes, charge current stepped down correctly at CV transition, and the fuel gauge IC tracked state of charge through a complete cycle.
  • Fuel gauge recalibration after install: On first use after installation, disable fast charging and run one full discharge-charge cycle. This lets the fuel gauge IC build a new discharge curve against the replacement cell before high-current charging pushes current into an uncalibrated cell.

Sudden shutdown at 20–30% on the Iconia Smart S300

This is a voltage cliff — the cell voltage drops sharply under display or modem load before the fuel gauge reads zero. The coulomb counter was calibrated to the old cell's discharge curve and doesn't match the new cell's steeper drop-off. Run one full discharge to automatic shutdown, then charge uninterrupted to 100% without unplugging early. After that cycle, the fuel gauge IC maps the correct cut-off voltage and shutdown behaviour stabilises.

Iconia Smart S300 not powering on after the battery sat in storage

Li-ion cells in long-term storage self-discharge. If the cell drops below approximately 2.5V, the BMS enters lockout to prevent damage and will not pass current to the device. The S300 will appear completely dead — no boot, no charge indicator. Connect the original Acer charger and leave it connected for at least 20–30 minutes before attempting to power on; the BMS needs a trickle current at a safe threshold before it re-enables the charge path and allows the cell to recover to a functional voltage.

Frequently Asked Questions

My Acer Iconia Smart S300 shows the wrong battery percentage after I put in the new cell — is something wrong with it?

Nothing is wrong with the cell. The fuel gauge IC stored the discharge curve of the old battery and is applying it to the new one. Run one complete discharge down to automatic shutdown, then charge to 100% without interruption. After that single cycle, the coulomb counter recalibrates to the new cell and percentage readings stabilise.

The Iconia Smart S300 feels warm near the battery while charging the new cell — should I be concerned?

A new Li-ion cell typically has slightly higher internal impedance than a broken-in cell, so the charge IC dissipates a little more energy as heat on the first few cycles. This is normal and reduces after 3–5 charge cycles as the cell conditions. If the device becomes hot to the touch rather than just warm, or if charging stops and a fault indicator appears, disconnect immediately and check that the connector is fully seated.

Fast charging stopped working on my S300 after I replaced the battery — what happened?

Some proprietary charge protocols require the BMS on the new cell to complete at least one full cycle before the handshake with the charge IC is accepted at high current. On the first cycle, charge via a standard 5V/1A USB source rather than a fast charger. Complete one full discharge-to-charge cycle, then reconnect your fast charger — the protocol negotiation should resume at the elevated current level.
