The DJI Osmo Action 4 Battery represents a compact powerhouse designed for adventurers and content creators who demand reliable performance in demanding environments. Built with lithium-ion chemistry, this battery excels at sustaining extended recording sessions—ideal for capturing action-packed moments without frequent swaps. Whether you're documenting extreme sports, outdoor expeditions, or travel vlogging, the battery's generous reserve enables uninterrupted capture of full-length sequences at standard resolution. Its rugged construction mirrors the durability of the camera itself, making it a trusted companion for those who push their equipment to the limit in unpredictable conditions.
Proper care of your DJI Osmo Action 4 Battery extends both its lifespan and your creative freedom on the field. Lithium-ion batteries perform best when cycled regularly and stored at moderate temperatures away from direct heat or extreme cold. Rather than depleting the battery completely before charging, adopting a habit of moderate top-ups during your day preserves the cell's health over time. When the camera sits idle for extended periods, storing the battery at a partial charge state reduces stress on the chemistry. Avoid exposing the battery to moisture or submerging it alongside your waterproof camera—the battery itself requires protection from the elements to maintain safe operation and peak performance.
With the fastest charger listed here (Dual battery charger, 40W) it takes about 31 min. With the slowest (Standard charger, 15W) it takes about 1 h 23 min. This compact action camera battery delivers up to 170 minutes of recording at 1080p resolution.
Frequently asked questions
- How long does it take to charge a DJI Osmo Action 4 Battery?
- From 0% to 100% with the standard 15W charger, it takes about 1 h 23 min. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
- How should I store my DJI Osmo Action 4 Battery when I'm not using the camera for weeks or months?
- Store the battery in a cool, dry place at partial charge (neither fully depleted nor fully charged) to minimize stress on the lithium-ion cells. Avoid storing it in vehicles, attics, or other locations subject to temperature extremes or high humidity. Periodically check on long-stored batteries and top them up if needed to maintain a healthy state of charge. This approach significantly slows the natural self-discharge and degradation processes inherent to Li-ion chemistry.
- Is it safe to leave my DJI Osmo Action 4 Battery charging overnight, and what precautions should I take?
- Modern DJI batteries include smart charging circuitry designed to halt overcharging, making overnight charging generally safe with an approved charger. However, good practice involves charging in a well-ventilated area away from flammable materials and never leaving charging batteries unattended for extended periods. Inspect the battery contacts and charger regularly for dirt or corrosion. If the battery becomes unusually warm during charging or refuses to hold charge, discontinue use and contact support—these are signs of potential internal issues requiring attention.
- How is this charge time calculated?
- We divide the energy needed (14.76 Wh times the percentage you're charging) by the charger's effective power, which is the charger's wattage times the battery chemistry's real-world charging efficiency (85% for Lithium-ion (Li-ion / Li-Po)). The same formula powers both this page and our API.
