Battery Care Tips
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
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.

Lenovo N22 Chromebook — 11.1V Li-Polymer Replacement Battery (5B10K88047)
This 11.1V, 3900mAh (43.29Wh) Li-Polymer battery replaces the original cell in the Lenovo N22 Chromebook and Chromebook N22-20 series. It fits models referenced under OEM part numbers 5B10K88047, 5B10K88048, L15L3PB1, L15M3PB1, and related variants. It restores battery-only operation to units where the original cell has degraded or failed.
- N22 Chromebook series fit: The N22, N22-20, and 80VH-series Chromebooks share the same three-cell Li-Polymer pack configuration, connector pinout, and BMS communication protocol — which is why a single part number covers the full lineup. Swapping a mismatched cell voltage or connector type will cause immediate BMS rejection.
- Bench tested on actual hardware: We ran this cell on an N22-20 unit and confirmed the BMS handshake completed without fault codes. The pack charged to full cutoff voltage and discharged to hibernate-level without triggering a protective shutdown at mid-range state of charge.
- Post-install calibration on the N22: After fitting this battery, run the charge down fully until the Chromebook hibernates on its own, then charge uninterrupted to 100%. Chrome OS uses this cycle to reset its fuel gauge IC against the new cell's actual capacity and clear the false "battery health poor" flag that appears after every cell swap on this platform.
Why Chrome OS shows "battery health poor" immediately after installing a new cell
Chrome OS stores battery health data in EEPROM tied to the original cell's charge history. When a new cell is installed, that stored data no longer matches the actual pack — so the OS flags it as degraded even though the cell is brand new. This is not a fault with the replacement battery. Running one complete discharge-to-hibernate followed by an uninterrupted full charge gives the fuel gauge IC new reference points and clears the warning.

This happens when the cell can no longer sustain voltage under combined CPU and display load — the pack voltage drops below the BMS cutoff threshold before the fuel gauge reaches 0%. On a worn original cell, this is a voltage cliff caused by internal resistance. On a freshly installed replacement, it almost always means the fuel gauge IC hasn't completed a calibration cycle yet and is reading state of charge from stale EEPROM data. Discharge fully to hibernate cutoff once, then recharge to 100% — after one full cycle the reported percentage and actual cutoff will align.

Frequently Asked Questions
Chrome OS says the battery is at 0% and won't show a charge level even after the laptop has been plugged in for an hour — what's happening?
The fuel gauge IC is reading EEPROM data from the old cell and can't map it to the new pack's charge curve yet. Leave the unit plugged in past the point where the charge LED turns solid — this lets the BMS complete its first full charge to cutoff voltage. Once the pack hits full charge, unplug, discharge to hibernate, then charge again uninterrupted. After that cycle the gauge IC has real reference data and the percentage will display correctly.
The N22 Chromebook stops charging at 80% and just stays there — is the replacement battery faulty?
This is almost always a BIOS-level charge limit, not a cell fault. Lenovo's firmware on the N22 series includes a battery protection mode that caps charging at 80% to reduce long-term cell stress — it can be toggled on or off in Lenovo Vantage or via the firmware settings if the feature is enabled on that unit. Check the battery charge threshold setting first before assuming the cell is the problem. If no charge limit is set in firmware and the pack still stops at 80%, cycle the battery once fully and re-test.
System info is showing the wrong Wh rating — 43Wh installed but the laptop reports a different number entirely. Which is correct?
The figure shown in system info is pulled from EEPROM on the original cell's BMS data — it reflects whatever rating was stored during the factory calibration of the old pack. The replacement cell's actual rated capacity is 43.29Wh as listed in the product specifications. The EEPROM-sourced number will update or recalibrate after the fuel gauge IC runs a full discharge-to-hibernate and recharge cycle against the new cell.
