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 6 / Kindle 4 Series — 3.7V Li-Polymer Replacement Battery (MC-265360)

This is a 3.7V, 750mAh (2.78Wh) lithium-polymer cell for the Amazon Kindle 6, Kindle 4, and Kindle 4G e-readers. It matches OEM part numbers MC-265360, 515-1058-01, and M11090355152. If your Kindle no longer holds a charge or fails to power on, this cell replaces the original.

  • Kindle 4 and Kindle 6 compatibility: Both generations share the same 3.7V Li-Polymer form factor, connector pinout, and BMS communication protocol — one cell fits the full range of D01100-series boards without modification.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on a Kindle 6 unit. The BMS accepted the cell on first connection, reported state-of-charge correctly, and held voltage above 3.5V through a sustained e-ink workload.
  • Post-swap charge cycle: After installing this cell, connect the Kindle to a USB charger and run a complete charge before use. The Kindle firmware recalibrates its battery percentage display against the new cell during that first full cycle — skipping it causes the percentage indicator to read incorrectly for days.

Why the Kindle 6 shows "Low Battery" immediately after a new cell is installed

Li-Polymer cells ship in storage mode, typically sitting between 3.6V and 3.7V — below the firmware threshold the Kindle treats as "charged." The device reads that resting voltage, flags it as low, and may refuse to boot past the USB charge screen. This is a voltage floor issue, not a faulty cell. Connect to USB power for at least 10 minutes and the Kindle will boot normally once the cell clears the minimum boot threshold.

Battery percentage jumping or freezing after a cell swap

The Kindle's fuel gauge IC learns cell characteristics over one or two full charge-discharge cycles. A brand-new cell has no learned profile, so the reported percentage can jump from 40% to 80% or freeze at a fixed number mid-use. This is firmware recalibration, not a hardware fault. Run two complete charge cycles — USB charge to 100%, use until the device warns low — and the percentage display will stabilise.

Frequently Asked Questions

My Kindle 6 won't turn on at all after I put in the new battery — is the cell dead?

Almost certainly not. Li-Polymer cells ship in storage state and the Kindle 6 requires a minimum of around 3.6V to complete its boot sequence. Connect the Kindle to a USB charger and leave it for 10–15 minutes before pressing the power button — the cell needs a surface charge before the board will start up.

The battery percentage on my Kindle 4 drops fast and then suddenly jumps back up — what's happening?

The Kindle's fuel gauge has no discharge history for the new cell, so it estimates capacity from a blank profile. That causes the percentage to drop steeply under load, then correct itself when the voltage recovers. Run two full charge-and-use cycles and the gauge will map the cell's actual capacity curve — the jumps stop after that.

Page turns feel sluggish right after I replaced the battery — was this not an issue before?

E-ink displays draw a voltage spike each time the screen refreshes. If the cell voltage is sitting low during the first charge cycle, the display controller throttles refresh speed to stay within the power budget. Charge the Kindle fully to 100% before reading — once the cell is at full voltage, page-turn response returns to normal speed.
