How Long to Charge a Sony A6700 Battery?
Charging a Sony A6700 Battery from empty to full takes about 360 h with its standard 8W charger. The battery holds roughly 2040 Wh, and this page estimates the time for every common charger wattage, using the Lithium-ion (Li-ion / Li-Po) chemistry it actually uses.

The Sony A6700's NP-FZ100 battery is engineered to support extended shooting sessions for both video production and rapid-fire autofocus tracking in stills mode. When integrating this compact mirrorless camera into your workflow—whether capturing wildlife, events, or cinematic video—the lithium-ion chemistry responds well to regular cycling rather than perpetual top-ups. Consider carrying a spare battery and rotating between them during fieldwork; this practice not only extends overall pack longevity but also ensures you're never left without power when the camera's autofocus system and articulating screen demand sustained energy draw.
To maximize the lifespan of your A6700 battery, store it in a cool, dry environment when not actively shooting, and avoid leaving it fully charged for prolonged storage periods. Lithium-ion packs benefit from partial-charge maintenance—keeping them at mid-level capacity during off-seasons reduces stress on the cells. Clean the battery contacts gently before each charge cycle, as debris or oxidation can impede efficient power transfer to the camera's fast hybrid AF system. Should you notice swelling, unusual heat during charging, or a significant drop in runtime, discontinue use immediately and replace the battery to maintain both safety and the A6700's renowned performance reliability.
With the fastest charger listed here (Fast dual charger, 24W) it takes about 120 h. With the slowest (Compact charger, 8W) it takes about 360 h. The Sony A6700 is a compact APS-C mirrorless camera that uses the NP-FZ100 battery, offering excellent autofocus performance for video and stills.
Frequently asked questions
- How long does it take to charge a Sony A6700 Battery?
- From 0% to 100% with the standard 8W charger, it takes about 360 h. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
- Why does my A6700 battery seem to drain faster when I'm using continuous autofocus or recording video?
- The NP-FZ100 battery works hardest during active autofocus tracking and video recording, especially with the A6700's real-time face and eye tracking enabled. These features demand consistent power delivery to maintain the camera's phase-detect and contrast-detect autofocus performance. If you're shooting demanding content, expect accelerated drain compared to interval shooting or stills-only workflows. To extend a session, disable continuous AF when framing static shots and switch to manual focus when the subject distance remains constant.
- Can I leave my Sony A6700 battery plugged in overnight, or should I unplug it once charging is complete?
- Modern lithium-ion chargers for the NP-FZ100, including Sony's standard charger, incorporate intelligent circuitry that prevents overcharging by cutting power once the pack reaches full capacity. However, routinely leaving batteries on the charger accelerates subtle degradation over months and years. For best longevity, unplug the battery shortly after charging completes. This habit is especially worthwhile if you shoot frequently and cycle multiple batteries; you'll notice more consistent runtime across your spare packs over time.
- How is this charge time calculated?
- We divide the energy needed (2040 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.
