Instead, the Speedlite pulls power from the battery to charge a capacitor. When the flash fires, the capacitor can instantly supply energy to power the bulb (partially or completely draining depending on the amount of light required). But once the capacitor is low, it needs time to pull more power from the battery (recycle time) before the flash is ready again. Recycle time will increase as the batteries get low on power. | |
