Product information

Description

The Extra Digital NB420421 battery is a lithium polymer replacement battery designed for 15" Apple MacBook Pro laptops. Engineered to restore portable power, this battery delivers a rated capacity of 8800 mAh and a black finish that integrates with the MacBook Pro chassis. It is intended as a direct replacement for worn or degraded internal batteries to extend run time and improve mobile productivity.

Advantages

This replacement battery uses Lithium Polymer (LiPo) technology to provide consistent voltage output and stable discharge characteristics, supporting typical laptop workloads. With an 8800 mAh nominal capacity, it offers extended operating time compared with depleted original cells, and its design focuses on compatibility and straightforward installation. The black casing provides a clean appearance while internal cell balancing helps maintain longer cycle life when used under normal charging conditions.

Suitable for

  • 15" Apple MacBook Pro models requiring an internal battery replacement
  • Users needing longer run time for mobile work and studies
  • Repair shops and technicians performing laptop battery swaps
  • Environments where a high-capacity, LiPo battery is preferred

Key specifications

  • Battery technology: Lithium Polymer (LiPo)
  • Nominal capacity: 8800 mAh
  • Color: Black
  • Form factor: internal notebook battery, designed for 15" MacBook Pro installation
  • Typical use: replaces depleted internal cells to restore laptop run time

How to use

Before installation, fully power down the MacBook Pro and disconnect any external devices. Remove the bottom case following the manufacturer or service guide and discharge static from your hands. Replace the old battery with the Extra Digital NB420421 unit, ensuring connector alignment and secure mounting according to the laptop's assembly points. Reassemble the case and perform a calibration cycle by charging the battery to full and allowing it to discharge to near empty at least once to help the system recognize capacity. If unsure, consult professional service or an authorized technician to avoid damage.

Usage recommendations

Use a compatible charger and avoid exposing the battery to extreme temperatures. For best long-term performance, keep the battery at moderate charge levels for storage (around 40–60%) and avoid repeated full discharges. If swelling, overheating, or abnormal behavior occurs, discontinue use and seek professional replacement.
