It is an aftermarket replacement battery for professional repair and refurbishment and should not be represented as a genuine Apple service battery.

Key Features

1. 6600mAh / 11.36V Battery Specification

The A1582 battery provides a rated capacity of 6600mAh with an 11.36V nominal voltage.

This equals approximately 74.98Wh of calculated battery energy.

2. Original-Energy-Class Replacement

Apple specifies the compatible MacBook Pro Retina 13-inch Early 2015 with a 74.9Wh built-in lithium-polymer battery. citeturn843430view0

The replacement battery's calculated 74.98Wh energy is therefore closely aligned with the original device's published energy specification.

3. Model-Specific Multi-Cell Structure

The battery uses a multi-section form factor designed around the internal notebook chassis.

Correct physical shape, screw positions, cable routing and connector alignment are essential for compatibility.

4. Professional Battery QC

Capacity, voltage, internal resistance, charging, discharge, aging and connector inspections help improve consistency across wholesale production batches.

5. OEM and Private Label Support

Custom labels, logos, barcodes, packaging and export cartons are available for repair brands, wholesalers and distributors.

B2B Quality Control

Incoming Cell Inspection

Battery cells should be checked for:

• Voltage

• Internal resistance

• Capacity consistency

• Self-discharge

• Thickness

• Appearance

Capacity Verification

Professional charge-discharge equipment should verify actual battery capacity against the approved 6600mAh specification.

Measured capacity is more important for wholesale quality control than printed capacity alone.

Voltage Testing

The battery pack should be tested against the approved 11.36V nominal specification.

Abnormal pack voltage may indicate inconsistent cells, protection-circuit issues or assembly defects.

Protection Circuit Testing

Battery electronics should be checked for safe charging, discharge and abnormal-condition protection.

Connector Inspection

The battery connector, cable, contact points and cable routing should be inspected for correct alignment and electrical continuity.

Charging and Discharging Test

Finished batteries should be tested for:

• Charging stability

• Discharge capacity

• Voltage consistency

• Abnormal shutdown

• Temperature behavior

Aging Test

Aging testing helps identify excessive self-discharge or unstable packs before shipment.

Final Inspection

Final QC should verify:

• Battery model

• Capacity

• Voltage

• Connector

• Physical dimensions
