The Panasonic Lumix S5II's DMW-BLJ31 battery is engineered to sustain demanding full-frame mirrorless shooting sessions, making it an essential power source for photographers who work in the field for extended periods. This lithium-ion battery responds well to modern charging practices: keeping it topped up before major shoots, avoiding complete discharge cycles whenever possible, and using the dedicated Panasonic charger designed for optimal performance will help maintain its health and longevity. Many S5II users find that a single battery comfortably covers a typical day of mixed shooting—from studio work to outdoor events—though having a second battery on hand eliminates anxiety during back-to-back assignments or travel situations.
Proper storage practices significantly extend the lifespan of your DMW-BLJ31, particularly if you plan to leave your S5II in a camera bag for weeks or months between uses. Lithium-ion chemistry benefits from being stored in a cool, dry environment at a partial rather than full charge state; repeatedly charging to capacity and leaving the battery at that level over time can stress the cells. If you notice the battery no longer holds a charge as robustly as when new, or if you experience unexpected shutdowns despite a seemingly adequate charge level, it's a clear sign that the battery has completed its useful cycle and warrants replacement—a normal occurrence with lithium-ion technology.
With the fastest charger listed here (Express charger, 62W) it takes about 42 h 49 min. With the slowest (Standard charger, 26W) it takes about 102 h 5 min. The Panasonic Lumix S5II full-frame mirrorless camera uses the DMW-BLJ31 battery with 1880mAh capacity for all-day shooting.
Frequently asked questions
- How long does it take to charge a Panasonic Lumix S5II Battery?
- From 0% to 100% with the standard 26W charger, it takes about 102 h 5 min. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
- Why does my S5II battery seem to drain faster when I use the camera's autofocus or video features heavily?
- Live autofocus tracking and especially continuous video recording demand sustained electrical current from the battery, quite different from the lower power draw of single-shot photography. The mirrorless sensor stays active during these operations, and features like image stabilization and lens motor operation also draw on the cell. This is entirely normal behavior for lithium-ion batteries under higher load; rotating in a fully charged backup battery is the practical solution for prolonged video or AF-heavy sessions.
- Is it safe to leave my DMW-BLJ31 in the charger after it reaches full charge?
- Modern Panasonic chargers are designed with smart circuitry that prevents overcharging by stopping the charging current once the battery is complete, making it safe to store a fully charged battery in the charger for short periods. However, for batteries you plan to store long-term, it's wiser to unplug them after charging and keep them in a cool location at a partial charge level, which aligns with best practices for lithium-ion longevity and reduces stress on the cell chemistry over months or years of intermittent use.
- How is this charge time calculated?
- We divide the energy needed (1880 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.
