Google Pixel Slate Compatible Battery 7.7V 6200mAh A70

Up to 19% off
New arrival
From $76.99 USD $94.99
Shipping calculated at checkout.
Fits Google Pixel Slate tablet; replaces OEM part number A70.
7.7V and 6200mAh capacity matches original cell output for full system functionality.
Connector slides straight into the internal slot with no locking tab or rotation needed.
We bench-tested this cell in a Pixel Slate unit; BMS accepted the pack on first charge cycle without fault codes.
After installation, run one full discharge to automatic shutoff then charge uninterrupted to 100% — this resets the fuel gauge IC calibration against the new cell and resolves inaccurate percentage display.

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.

Google Pixel Slate — 7.7V Li-Polymer Replacement Battery (A70)

This is a 7.7V, 6200mAh (47.74Wh) Li-Polymer battery for the Google Pixel Slate tablet. It replaces part number A70, the internal cell that powers the Slate's Chrome OS environment, display, and wireless radios. Fit this when the original no longer holds a charge or causes unexpected shutdowns.

  • Pixel Slate compatibility: The Slate uses a single large Li-Polymer pouch cell at 7.7V to drive the high-resolution display, dual-band Wi-Fi, and Chrome OS background processes simultaneously. This cell matches that voltage rail and the original connector orientation.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Pixel Slate's charge IC. The BMS communicated correctly, accepted a full charge without fault codes, and delivered stable voltage through display-on plus Wi-Fi active load.
  • Fuel gauge recalibration after swap: After installation, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. The Slate's fuel gauge IC was calibrated to the old cell — this single cycle resets it against the new cell and clears the inaccurate percentage reading that commonly appears after a swap.

Why the Pixel Slate shuts down at 15–25% remaining

The Pixel Slate draws a combined load from its QHD display and Wi-Fi radios that spikes current demand significantly during active use. Aged or new-but-uncalibrated cells show a steep voltage cliff under this combined load — the BMS reads the voltage drop as a low-cell event and trips a protective shutdown before the percentage indicator catches up. This is not a hardware fault. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% and the fuel gauge IC recalibrates its curve against the actual cell capacity.

Fast charging unavailable after battery replacement

After a cell swap, the Pixel Slate's charge controller may default to standard 5V charging until it has completed one accepted USB-PD negotiation cycle with the new cell in circuit. If fast charging is absent on the first session, do not assume a faulty battery or charger. Plug in using the original Google USB-C charger or a certified USB-PD adapter, let the device complete a full charge uninterrupted, and USB-PD negotiation typically re-establishes at the correct voltage on the next session.

Frequently Asked Questions

My Pixel Slate is showing the wrong battery percentage after I replaced the battery — is the new cell faulty?

No — the fuel gauge IC on the Pixel Slate was calibrated to the resistance and capacity curve of the old cell. A new cell throws that calibration off, which causes the percentage display to read incorrectly from the start. Run one full discharge to automatic shutoff, then charge uninterrupted to 100% without using the device. That single cycle resets the fuel gauge IC against the new cell and the percentage reading stabilises.

The Pixel Slate cuts out suddenly under 20% even though the battery shows charge remaining — what's causing this?

This is a voltage sag issue, not a faulty cell. Under the combined draw of the QHD display and active Wi-Fi, current demand spikes and the cell voltage drops sharply in the lower state-of-charge range. The BMS reads that drop as a critically low cell event and trips a shutdown before the on-screen percentage has time to reflect it. Complete one full recalibration cycle — discharge to automatic shutoff, then charge uninterrupted to 100% — and the fuel gauge curve will match the actual cell behaviour.

The Pixel Slate feels warm near the charging port during the first charge after swapping the battery — should I stop charging?

Warmth during the first charge on a new cell is normal. The charge IC runs through an initial conditioning phase with a new cell where it probes the cell's internal resistance before settling into its standard CC/CV profile. That process generates slightly more heat than a routine charge. As long as the device is not hot to the touch and Chrome OS shows no charge fault, continue the session. If the device reaches a temperature that triggers a Chrome OS thermal warning, disconnect and let it cool to room temperature before resuming.
