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.

Amazon Kindle 3 — 3.8V Li-Polymer Replacement Battery (S11GTSF01A)

This 3.8V, 3500mAh lithium-polymer cell replaces the original battery in the Amazon Kindle 3 e-reader, including the Kindle 3 Wi-Fi and Kindle 3G variants. It matches OEM part numbers S11GTSF01A, GP-S10-346392-0100, 170-1032-01, and 170-1032-00. Capacity is rated at 13.3Wh — matched to the original cell specification.

  • Kindle 3 platform fit: The Kindle 3 Wi-Fi and 3G share the same battery bay, connector pinout, and BMS handshake protocol. All variants accept the same cell — voltage rail and thermistor line are identical across the range.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on Kindle 3 hardware. The BMS accepted the cell without error flags, and battery percentage reporting stabilised after one complete charge cycle.
  • First-charge calibration after swap: After fitting this cell, connect the Kindle to a USB charger and let it complete a full charge before use. The Kindle 3 firmware reads battery percentage from a fuel gauge that recalibrates to a new cell during that first uninterrupted charge — skipping it causes erratic percentage readings.

Why the Kindle 3 won't boot after a battery swap

Lithium-polymer cells ship at storage voltage — typically 3.6V to 3.7V. The Kindle 3 requires a minimum boot voltage closer to 3.75V before it will power on. If you press the power button immediately after fitting the new cell and nothing happens, the cell is not faulty — it is simply below the boot threshold. Connect the USB charger and leave it for 10 minutes before attempting to power on again.

Battery percentage jumping or reading 0% on a freshly installed cell

The Kindle 3 uses a coulomb-counter fuel gauge that tracks charge relative to a baseline set during calibration. A new cell has no calibration baseline stored, so the firmware cannot accurately estimate state of charge until it has seen one full charge cycle from near-empty to 100%. Until then, the percentage display may jump between readings or show 0% even when the device is running. Charge the device to 100% without interruption — the gauge will lock to the new cell's capacity curve and stabilise from that point forward.

Frequently Asked Questions

My Kindle 3 screen is slow to turn pages after fitting the new battery — is something wrong?

Page turn lag on the Kindle 3 is almost always a voltage issue. The e-ink display requires a short high-voltage pulse to refresh — when cell voltage sags below roughly 3.7V, that pulse takes longer to generate and the refresh slows visibly. If the cell hasn't completed its first full charge cycle, voltage can sit lower than normal under load. Charge to 100% and run one full cycle; page turn speed should return to normal once the cell is operating at rated voltage.

The Kindle 3 shows a low battery warning the moment it powers on with the new cell — do I have a faulty unit?

The cell shipped at storage voltage, which the Kindle 3 firmware interprets as a critically low state of charge. This is normal for a new lithium-polymer cell that hasn't been charged since leaving the warehouse. The device is not faulty. Connect it to USB immediately and allow it to charge to 100% without interruption — the warning will clear and the percentage display will read correctly once the fuel gauge completes its first calibration cycle.

WiFi sync is draining the Kindle 3 battery noticeably faster than just reading — is the new cell underperforming?

The Kindle 3 WiFi radio draws significantly more current than the e-ink display alone — roughly 10 to 15 times higher during an active sync. This is expected hardware behaviour, not a cell defect. If you sync books infrequently, switch WiFi off in the Kindle's settings between downloads and turn it on only when needed. With WiFi off, the display-only draw is low enough that a full 3500mAh cell will last through extended reading sessions without issue.
