Kastar 11.1V 4400mAh LP-E4N Camera Battery - Fully Decoded

In this review the Kastar 11.1V 4400mAh LP-E4N replacement battery is judged on fit, compatibility, and real-world runtime for older Canon professional bodies. The bottom line: it is a reliable, fully decoded replacement for LP-E4 and LP-E4N users who need a higher capacity spare that the camera and original charger will recognize. For photographers who shoot extended sessions on Canon EOS 1D series bodies, the single biggest reason to buy is the combination of a large 4400mAh capacity and a decoded battery ID that displays remaining charge in-camera.

Key Features

• Fully decoded support: The battery is recognized by compatible Canon cameras so the remaining charge is displayed accurately in-camera, avoiding guesswork during shoots.
• High capacity: At 4400mAh, the pack delivers longer runtime than many OEM options, reducing battery swaps on long shoots or video sessions.
• Original charger compatible: The pack charges with Canon LC-E4 and LC-E4N chargers so no special third-party charger is required.
• Safety protections: Built-in protection circuitry guards against over-charge, over-discharge, over-voltage, over-current, and overheating for safer operation.
• Industry safety standards: Cells meet UL1642 and CE standards, which helps assure basic safety and build quality in the replacement pack.

Who It's For

This battery is best for photographers and videographers who use Canon EOS 1D series cameras and need a dependable spare or replacement with longer run times and accurate charge reporting. It suits professionals who prefer to charge with existing Canon LC-E4/LC-E4N chargers and want a pack with safety protections built in.

Casual users of more modern mirrorless or entry-level bodies should look elsewhere if they do not own a compatible charger or camera model, because compatibility is focused on LP-E4 / LP-E4N systems and older Canon pro bodies.
