The Canon PowerShot G7X Mark III's NB-13L lithium-ion battery is engineered to match the sophisticated demands of a premium compact camera, delivering consistent power through extended shooting sessions whether you're capturing street photography, travel moments, or studio work. Because this camera consolidates professional-level imaging into a compact form factor, your battery becomes the critical link between inspiration and execution—understanding how to charge and maintain it properly ensures you're never caught without power when the perfect shot presents itself. Lithium-ion chemistry thrives on regular, moderate use rather than extreme discharge cycles, so developing a habit of opportunistic top-ups throughout your day often yields better long-term battery health than waiting for complete depletion.
Storage and seasonal care matter more than many photographers realize, particularly if your G7X Mark III spends weeks between uses. When putting your camera away for an extended period, storing the NB-13L at partial charge in a cool, dry environment slows the natural aging process inherent to lithium-ion cells. Avoid leaving the battery connected to the camera or charger during storage, as this subjects it to a slow parasitic drain and potential overcharge scenarios that degrade performance over time. If you travel frequently with your compact camera system, keeping a second battery conditioned and ready—rather than pushing a single cell to its limits—mirrors professional workflow practices and provides both reliability and peace of mind in unpredictable shooting environments.
With the fastest charger listed here (Fast charger, 15W) it takes about 46 min. With the slowest (Standard charger, 5W) it takes about 2 h 19 min. The Canon PowerShot G7X Mark III is a premium compact camera with a 1-inch sensor that utilizes the compact NB-13L battery.
Frequently asked questions
- How long does it take to charge a Canon PowerShot G7X Mark III Battery?
- From 0% to 100% with the standard 8W charger, it takes about 1 h 27 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 NB-13L battery when I won't be using my G7X Mark III for several weeks?
- Remove the battery from the camera and store it separately in a cool, dry place at roughly half charge. Avoid storing it fully depleted or fully charged, as both states accelerate chemical degradation in lithium-ion cells. If your camera will sit unused for months, check the battery's charge level every few weeks and top it up to the midpoint if needed. This practice preserves capacity and responsiveness for your next shooting session.
- What's the best charging approach for frequent users who shoot multiple times per week?
- Rather than draining the NB-13L completely and then fully recharging it each cycle, adopt a pattern of charging when the battery indicator drops to low—this lighter cycling habit extends the lifespan of lithium-ion chemistry considerably. If you find yourself shooting regularly, owning a second battery allows you to rotate between them, evening out usage wear across both cells and ensuring you always have a charged backup ready without forcing rapid recharge sessions that generate excess heat.
- How is this charge time calculated?
- We divide the energy needed (8.2 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.
