About this replacement
Apple MacBook Pro 13.3 — 11.1V Li-Polymer Replacement Battery (A1713)
This is an 11.1V, 4700mAh Li-Polymer battery for the Apple MacBook Pro 13.3, including the Late 2016 models. It replaces OEM part A1713 and fits configurations such as MLL42CH/A and MLUQ2CH/A. Install it when the original cell has degraded to the point where the laptop no longer holds a useful charge away from the AC adapter.
- Late 2016 13.3-inch compatibility: The Late 2016 Pro 13.3 chassis uses a fixed connector pinout tied to the A1713 part number. The BMS handshake and voltage rail match across all SKUs in this generation, so the same cell fits both Touch Bar and non-Touch Bar variants covered by this listing.
- Bench tested on actual hardware: We ran this cell through charge and discharge on a Late 2016 MacBook Pro 13.3. The BMS accepted the cell without error, and the charge controller reached full voltage without thermal cutoff or authentication rejection.
- Post-install calibration for this model: After fitting, run the laptop down to hibernate cutoff on battery power alone, then charge uninterrupted to 100%. This resets the fuel gauge IC learn cycle and clears the false low-health warning that macOS logs after every cell swap on this generation.
macOS reporting poor battery health immediately after fitting A1713
The Late 2016 MacBook Pro stores battery health data in EEPROM on the old cell. When a new cell goes in, the system reads no accumulated cycle data and flags the health as degraded or unknown. This is not a fault with the replacement. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100% and macOS will re-baseline the health indicator against the new cell chemistry.

This happens when the cell voltage drops below the BMS cutoff threshold under combined CPU and display load before the fuel gauge registers empty. The gauge IC was calibrated against the old, worn cell and no longer maps accurately to the new one. The fix is the same calibration cycle — discharge fully to hibernate, then charge to 100% without interruption. After two to three full cycles the shutdowns stop and the percentage readout tracks correctly to the cell's actual voltage floor of around 9V under load.
