Fits Apple MacBook Air 11" A1465 2013 and replaces OEM part A1495.
7.6V and 5100mAh lithium-polymer cell delivers the original power output for full system operation.
Connector slides into the internal battery slot with a single locking tab on the left edge.
We bench-tested the cell on a Mid-2013 A1465 — BMS accepted the pack on first insertion with no fault codes.
After installation, run one full discharge to sleep cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

Apple MacBook Air 11" A1465 Mid-2013 — 7.6V Li-Polymer Replacement Battery (A1495)

This is a 7.6V, 5100mAh (38.76Wh) lithium-polymer battery for the Apple MacBook Air 11-inch A1465, Mid-2013 models. It fits both the Core i5 1.3GHz and Core i7 1.7GHz variants, including MD711LL/A. OEM part numbers A1495 and 020-8084-A both apply to this cell.

  • A1465 Mid-2013 compatibility: The Core i5 and Core i7 Mid-2013 A1465 boards share the same connector pinout, voltage rail, and BMS handshake protocol. Both pull from this same cell without modification.
  • Bench tested on actual hardware: We ran this cell through charge-discharge cycles on an A1465 board. The BMS negotiated correctly, SMC recognised the battery, and charge current stabilised at the expected rate through each phase.
  • SMC learn cycle after install: After fitting, run the MacBook down to automatic hibernate cutoff, then charge uninterrupted to 100% without interruption. This resets the SMC battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

Why macOS reports poor battery health immediately after a cell swap

The MacBook Air's SMC and macOS store cycle count and health data from the previous cell in EEPROM. When a new cell is installed, that stored data does not match the fresh chemistry, so macOS flags the battery as degraded or unknown before any cycles have run. This is a data mismatch, not a fault with the replacement cell. Running one full discharge-to-hibernate and then an uninterrupted full charge gives the SMC enough data to rewrite its baseline and return an accurate health reading.

MacBook shuts down at 20–30% charge shown on the status bar

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual discharge curve. The percentage shown reflects the old cell's voltage map, so the system hits a voltage cliff — where the cell can no longer sustain the combined CPU and display load — well before the gauge reaches zero. The fix is the same SMC learn cycle: discharge fully to hibernate, then charge to 100% without interruption. After two to three full cycles, the fuel gauge IC recalibrates and the shutdowns stop.

Frequently Asked Questions

macOS System Information shows the wrong Wh rating after I swapped the battery — is something wrong with the cell?

The Wh figure in System Information pulls from EEPROM data written by the original cell, not from a live measurement of the new one. After the SMC learn cycle completes — one full discharge to hibernate, then a full uninterrupted charge to 100% — the system rewrites that value against the new cell's actual capacity. If it still reads incorrectly after two full cycles, reset the SMC by holding Shift + Control + Option + Power for ten seconds with the charger connected.

The battery percentage jumps around wildly for the first few charge cycles — drops from 60% to 10% with no warning — is the cell defective?

The fuel gauge IC on the A1465 board needs two to three full calibration cycles to build an accurate discharge model for the new cell. Until then, the percentage shown is mapped against the old cell's curve, which causes sudden jumps and inaccurate readings. Run two complete discharge-to-hibernate cycles followed by full uninterrupted charges. By the third cycle the gauge IC has enough real data to track the new cell accurately.

Charge stopped at 80% and won't go higher — MagSafe shows green but the percentage is stuck — what's happening?

macOS has a built-in BIOS-level charge limit that activates when it detects certain battery health conditions or when Optimized Battery Charging is enabled. This is firmware behaviour, not a fault with the cell. Open System Preferences → Battery → uncheck Optimized Battery Charging, then plug in and allow a full charge cycle to 100%. If the limit persists after that, reset the SMC to clear any charge threshold the firmware locked in from the previous cell.
