Quick Answer
The Polaroid EN-EL18 battery is a reliable, longer-lasting alternative to the Nikon original, fully compatible with Nikon cameras that use the EN-EL18 pack. It offers premium Li-ion polymer cells with no memory effect, making it ideal for extended shoots.
Why Choose the Polaroid EN-EL18?
The Polaroid EN-EL18 battery directly replaces the Nikon EN-EL18 pack. Its Li-ion polymer cells provide a longer run-time between charges compared to standard lithium-ion batteries. This means fewer interruptions during long photo sessions or video recording.
A key advantage is the no-memory-effect design. You can recharge the battery at any point without waiting for a full discharge, which simplifies your workflow and helps maintain consistent performance over time.
What to Know About Compatibility
The Polaroid EN-EL18 is fully compatible with Nikon cameras that use the original EN-EL18 battery. This includes high-end DSLRs like the Nikon D4, D4S, D5, and D6, as well as the Nikon D800/D800E with the optional MB-D12 battery grip. It also works with the D810, D850, and similar models when using the appropriate grip.
However, the battery does not include a charger. You will need a Nikon EN-EL18 charger or a compatible third-party charger to recharge it. If you are starting from scratch, factor in the cost of a charger.
Lifespan Considerations
Thanks to the premium Li-ion polymer cells, the Polaroid EN-EL18 delivers a longer run-time per charge than many generic alternatives. The no-memory-effect chemistry also means you can top off the battery without reducing its total lifespan.
Like all rechargeable batteries, the Polaroid EN-EL18 will gradually lose capacity after hundreds of charge cycles. For most photographers, this translates to several years of reliable use before noticeable degradation.
Decision Rules for the Polaroid EN-EL18
- Check Camera Compatibility: Verify your Nikon camera or battery grip accepts the EN-EL18 battery. Models include D4, D4S, D5, D6, D800/D800E (with MB-D12 grip), D810, D850 (with grip).
- Plan for a Charger: The Polaroid EN-EL18 does not include a charger. If you do not already own a compatible EN-EL18 charger, purchase one separately before your first use.
- Expect Longer Run-Time: The Li-ion polymer cells provide a longer run-time than standard lithium-ion batteries. Use this to your advantage for extended shoots or video recording.
- No Memory Effect Means Flexible Recharging: You can recharge the battery at any point without waiting for a full discharge. This reduces downtime and helps maintain long-term capacity.
