FJ400 Battery: Performance and Care
FJ400 Performance & Sleep Modes
The FJ400 Lithium-Polymer Battery (14.8V 65Wh, 4400mAh) is capable of 480+ full-power flashes with
the modeling lamp disabled. In order to operate the FJ400 with the AC power supply, the FJ400 battery
must have a remaining charge of ≥ 25% capacity.

FJ400 Charging & Life Expectancy
The average charge time is 2.5 hours from complete discharge. The FJ400 Lithium-Polymer Battery
(14.8V 65Wh, 4400mAh) will achieve at least 300 complete charge cycles. Continued usage beyond the
expected charge cycles will result in diminished performance and the ability to hold a charge. Avoid
charging and using the battery outside of the stated operating temperatures (
32~104°F / 0~40°C ) as it will
affect the overall performance of the battery and strobe. Preserve the longevity of the battery by storing
at roughly ~40% capacity at room temperature in a dry environment and recharge to this capacity at least
every 3 months when not being used.
