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.

Acer Chromebook Spin 311 CP311-3H-K2RJ — 7.5V Li-Polymer Replacement Battery (AP16L8J)
This is a 7.5V, 4800mAh (36Wh) Li-Polymer battery for the Acer Chromebook Spin 311 CP311-3H-K2RJ convertible laptop. It also fits the CP311-3H and Spin 513 CP513-1H and CP513-1HL series. Part numbers AP16L8J, KT.0020G.010, KT.00205.008, KT.00205.002, and AP16L5J all cross to this cell.
- Spin 311 and Spin 513 shared platform: Both series run the same 7.5V two-cell Li-Polymer architecture with a matching connector pinout and BMS handshake protocol — that is why one SKU covers both lines. Swap one and the firmware reads the cell correctly without additional configuration.
- Bench tested on actual hardware: We ran this cell through the Spin 311 charge controller and confirmed the BMS negotiated full charge acceptance at 8.7V cutoff. No false full-charge flags and no thermal events during the charge cycle.
- First cycle after installation: After fitting this cell, run the Chromebook down to automatic hibernate-cutoff under normal screen and CPU load, then charge uninterrupted to 100%. This forces the battery learn cycle to reset, which clears the inaccurate health warning that appears in ChromeOS after any cell swap.
Why ChromeOS reports poor battery health immediately after a cell swap
The Chromebook's embedded controller stores charge history and health metrics in EEPROM tied to the old cell. When a new cell goes in, the controller reads stale data and flags health as poor or unknown before any cycles have run. This is not a fault with the replacement cell. One full discharge-to-hibernate followed by an uninterrupted charge to 100% triggers the battery learn cycle, which writes fresh baseline data to the controller and clears the warning.
Spin 311 shutting down at 20–30% charge shown on screen
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The IC is still using the old cell's discharge profile, so it calls a low-voltage shutdown earlier than the real cutoff. It is not a defective cell. Run two to three full discharge-to-hibernate and full-charge cycles and the fuel gauge re-maps itself against the new chemistry — shutdowns will stop occurring above 4.0V per cell.

Frequently Asked Questions
ChromeOS says my new battery is in poor health right after I installed it — is the cell actually bad?
The cell is fine. The Chromebook's embedded controller reads health data from EEPROM written by the old battery, and that stale data triggers a false poor-health flag on the replacement. Run the laptop down to automatic hibernate-cutoff under normal use, then charge it uninterrupted to 100%. That single learn cycle rewrites the EEPROM baseline and clears the warning.
My Chromebook Spin 311 shows a Wh rating in system info that doesn't match the 36Wh spec on the listing — which one is correct?
The 36Wh figure from the product data is the actual measured cell capacity. The system info figure comes from the Wh value stored in the battery's EEPROM, which reflects the original OEM cell's rated chemistry rather than the installed cell's real output. The two numbers differ because EEPROM data is not rewritten on swap. Trust the 36Wh spec for actual capacity — the system info figure is a firmware artefact, not a measurement.
New battery charges fine but the percentage jumps around wildly for the first few uses — what's causing that?
The fuel gauge IC calibrates its state-of-charge model against a learned discharge curve. With a new cell in place, it has no accurate curve yet and interpolates badly, which causes the percentage to skip or drop suddenly. This is normal behaviour for the first two to three cycles. Run full discharge-to-hibernate and full-charge cycles without interruption and the gauge IC will lock onto the correct voltage-to-capacity curve and stabilise.
