Kastar Battery (3-Pack) for Nik EN-EL4 / EN-EL4A - High Capacity

In this review the Kastar Battery (3-Pack) is evaluated for photographers who need reliable spare power for older Nik cameras and grips. The bottom line: this replacement pack is best for active pros and enthusiasts who use models like the D2 series, D3 series or D300/D700 and need extended runtime without swapping to proprietary cells. The review finds the pack delivers high capacity and modern protection electronics, making it a practical, lower-cost way to keep multiple camera bodies and an MB-D10 grip running through long shoots.

Key Features

• Compatibility: Works as a replacement for EN-EL4 and EN-EL4a batteries so it fits many Nik D2, D3, D300 and D700 models and compatible grips.
• High Capacity: Each battery is rated 3200mAh at 11.1V which provides longer runtime compared with typical older cells.
• Japanese cells: Uses high quality Japanese cells to reduce memory effect and maintain capacity over repeated charge cycles.
• Integrated protection: Built-in microchip helps prevent overcharge and overdischarge for safer use with original camera electronics.
• Value pack: The 3-pack supplies multiple spares so photographers can keep extra batteries in camera bags or grips for extended field work.
• Warranty: Includes a 30-day money back and 3-year manufacturer warranty for purchase protection.

Who It's For

This pack is aimed at photographers who own legacy Nik cameras that accept EN-EL4 style batteries, including studio shooters who rotate bodies and wedding or event shooters who need hot-swappable spares. It suits camera users who want the convenience of multiple charged batteries without paying original-brand premiums.

It is not for those who need a single OEM-labeled battery for warranty reasons with camera manufacturers, or users of newer cameras that require different battery chemistry or form factors; buyers must also note that some grips require an extra BL-3 battery chamber cover which is not included.

Pros & Cons

Pros

• High 3200mAh capacity provides noticeably longer runtime between charges.
• Three batteries in the package reduce downtime on long shoots and simplify logistics.
• Integrated protection microchip improves safety and compatibility with camera charging circuits.

Cons

• Package does not include a BL-3 battery chamber cover required by some grips, which must be purchased separately.

Specifications
