New arrival
From $136.99 USD $165.99
Shipping calculated at checkout.
Fits Apple MacBook Pro 17 models A1297, A1383, and MC226 series laptops.
10.95V nominal voltage, 6900mAh capacity delivers 75.56Wh to sustain processor and display load cycles.
Connector type is proprietary Apple magnetic contact; orientation locks in one position on the MacBook Pro 17 chassis.
Bench testing on a 2009 MacBook Pro 17 showed normal BMS ramp and full charge acceptance without fault codes.
After installation, run one complete discharge to sleep-mode cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings that appear after cell swaps.

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 Pro 17 — 10.95V Li-Polymer Replacement Battery (A1383)

This is a 10.95V, 6900mAh (75.56Wh) lithium-polymer replacement battery for the Apple MacBook Pro 17-inch. It fits the A1297 chassis across 2009 and later versions, including MC226 and MD311 configurations. OEM part numbers covered include A1297, A1383, and 020-7149-A.

  • MacBook Pro 17 A1297 compatibility: All A1297 chassis revisions from 2009 through 2011 share the same battery bay dimensions, six-pin Smart Battery connector, and 10.95V power rail. The SMC communicates with the battery over SMBus — the BMS on this cell speaks that protocol correctly.
  • Bench tested on actual hardware: We ran this cell on an A1297 logic board and confirmed the SMC recognised it without faults. The BMS held charge regulation cleanly across a full cycle, and the SMC did not throw a Service Battery alert during the test run.
  • SMC calibration after install: After fitting this cell, run the laptop on battery until it reaches hibernate cutoff, then charge uninterrupted to 100%. This resets the SMC battery learn cycle and prevents the inaccurate health warning macOS displays after any cell swap on this model.

Why macOS reports "Service Battery" immediately after fitting a new A1383 cell

The A1297 SMC reads cycle count, full-charge capacity, and design capacity from the battery's EEPROM on first boot. A new cell carries factory EEPROM values that do not match the learned data from the old cell, so the SMC flags a mismatch. This is not a fault with the replacement — it is a data conflict. Running one full discharge-to-hibernate followed by a complete uninterrupted charge clears the flag by giving the SMC a fresh dataset to write. After two to three cycles, the health indicator stabilises.

MacBook Pro 17 shutting down abruptly at 20–30% charge shown

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual discharge curve. The gauge predicts 20–30% remaining based on the old cell's characteristics, but the new cell's voltage drops faster under full CPU and display load — the SMC sees a low-voltage cliff and shuts down before the displayed percentage reaches zero. The fix is calibration: discharge fully to hibernate cutoff, then charge to 100% without interruption. Repeat this cycle twice more, and the fuel gauge IC recalculates the curve against the actual cell chemistry. After three full cycles, shutdowns at false percentages stop.

Frequently Asked Questions

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

Nothing is wrong with the cell. The Wh figure shown in System Information pulls from the EEPROM on the battery, and the rated design capacity stored there can differ slightly from actual chemistry output on a new cell. The SMC recalculates the real full-charge capacity over the first few charge cycles and updates the figure accordingly. After three full discharge-to-charge cycles, the Wh reading in System Information reflects the actual cell capacity.

The battery charge is stopping at 80% and won't go higher — did I get a faulty unit?

This is almost always a BIOS-level charge limit, not a cell fault. Apple's SMC firmware on some A1297 machines activates a charge threshold when it detects certain battery health flags from the previous cell's EEPROM data. Reset the SMC by shutting down, then holding Shift + Control + Option + Power for ten seconds with the charger connected, then release and power on. After the SMC reset, plug in the charger and allow a full uninterrupted charge — the 80% cap clears in most cases on the first post-reset cycle.

My MacBook Pro 17 is reading the new battery as "0%" and won't boot on battery power at all straight out of the box — what's happening?

A lithium-polymer cell shipped at storage charge (typically 30–50%) can read as 0% if the SMC has no valid EEPROM handshake data from a previous cycle on that cell. Connect the MagSafe charger, let the laptop charge without booting for 15 minutes, then power on — the SMC needs a partial charge present before it can initialise communication with a new cell. If the reading stays at 0% after 30 minutes on charge, hold the power button for ten seconds to force an SMC re-read, then check that the battery connector is fully seated at 10.95V.
