About this replacement
Amazon Kindle S11S01A / D00701 — 3.7V Li-ion Replacement Battery (S11S01B)
This is a 3.7V, 1100mAh Li-ion cell that fits the Amazon Kindle S11S01A, D00701, and D00701 WiFi e-readers. It replaces the original S11S01B battery when capacity has dropped and the device can no longer hold a useful charge. Dimensions are 65.54 × 53.20 × 4.96mm — measure your existing cell before ordering if you are unsure.
- S11S01A and D00701 compatibility: Both models share the same physical footprint, connector pinout, and 3.7V voltage rail. The BMS on each device uses the same charge-termination handshake, so one cell covers the full group without modification.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the S11S01A platform. The BMS accepted the cell cleanly, hit full charge termination at 4.2V, and the e-ink controller drew steady current with no BMS fault interruptions.
- Post-swap charge cycle on Kindle firmware: After installing this cell, connect the Kindle via USB and charge it completely before switching it on. Kindle firmware reads the battery percentage from a coulomb counter that resets on cell swap — skipping the full charge cycle causes the percentage display to report incorrect figures from the first boot.
Kindle not powering on after battery swap
Replacement cells ship in storage mode — typically around 3.0V to 3.3V. The Kindle's boot sequence requires a minimum voltage on the battery rail before the processor will initialise. If the cell voltage sits below that threshold, the device shows nothing when you press the power button. Connect the USB charger immediately after installation and leave it for at least 10 minutes before attempting to power on. The charge circuit will raise the cell voltage into the boot window, and the Kindle will start normally from that point.
Battery percentage jumping or reading 0% right after a new cell
The Kindle's fuel gauge IC tracks charge state by counting current in and out of the cell over time. A brand-new cell has no history in that counter, so the reported percentage is effectively a guess until a full charge-to-discharge cycle completes. Percentage jumps of 20–30% in either direction are normal in the first few sessions. Run the device from 100% down to auto-shutdown at least once, then charge back to 100% — the firmware recalibrates the gauge to the actual cell capacity after that cycle.
