FL stands for fluid - it is the e-liquid gauge, not the battery. Here is how to read the rest of the screen too.
On AliBarBar devices with a display, FL is the e-liquid (fluid) level remaining inside. It sits alongside a separate battery readout, and the two fall at different rates - which is the whole point of showing both. Watching FL tells you how much vaping is genuinely left; watching the battery only tells you when to reach for a cable.
| FL | Fluid - e-liquid remaining. When it empties, the device is finished. |
|---|---|
| Battery icon / bars | Charge remaining. On the rechargeable UPLOAD and Ice Adjust, top up over USB-C; this refills, FL does not. |
| Puff counter | Puffs taken, on models that track it. |
| Charging animation | Cycling bars mean it is charging; a steady full icon means it is done. |
That's the device telling you it has reached the end of its life. The e-liquid is spent, and no amount of charging brings it back - AliBarBar disposables cannot be refilled, and opening one to try is neither safe nor sensible. Flavour going flat and vapour thinning out are the same message in a different form. Recycle it and start a fresh one.
On the rechargeable models - the UPLOAD and Ice Adjust - just plug into USB-C and the battery tops back up until the FL gauge finally empties. The Swirl, INGOT and Pandora aren't rechargeable; their battery is sized to outlast the liquid, so a flat one with plenty of FL still showing is a rare faulty unit - message us and we'll replace it.
FL means fluid - the e-liquid level remaining in the device. It is shown separately from the battery indicator.
The device is finished. E-liquid cannot be refilled, so recycle it responsibly and start a new one.
No. FL is the e-liquid gauge. The battery has its own icon, and recharging refills the battery only.
If the FL gauge is empty, the e-liquid is spent and the device has reached the end of its life even with a charged battery.
