The glowing or flashing red light on the JBL Charge 5 speaker.
The JBL Charge 5 has a group of LEDs behind a translucent white bar in its front lower area. This displays battery charge level whether it’s draining or charging. Furthermore, this gauge shows charging progress, or how full the battery is at a given time. It also tells you how much “juice” the battery has left as the battery discharges. In this piece we discuss how to check JBL Charge 5 battery, by reading this meter.
When you power down the 5 with no charger connected, no lamps light up. This bar also is dark when a charger IS present, but the battery finished charging to full. The battery gauge is on the front lower portion of the speaker in the center.
There are five tiny LED lamps inside the 5, that illuminate the battery meter bar in various degrees. These light in succession as the speaker charging fills the battery. The 5 is recharging when you see part of the bar pulsing white. When the battery is near empty, the bottom edge of the bar blinks white while charging. Then as charging continues, more of the bar lights up, and flashing end of the bar moves up.
Note though, that you may see the bottom most part of the meter flash red. This does not mean that charging is proceeding. Instead, it means that the battery is critically low and that you should recharge the 5immediately.
It only flashes red like this when the battery is nearly dead and AC power has not yet present. But when you do that, this red flashing light begins blinking white. Remember though, that this light never pulses red while charging is happening.
As charging progresses, more of the meter lights solid. That is, the flashing LED moves further up, until that blinking reaches the topmost area of the bar.
Battery charging is complete when all but the very last little segment of the indicator lights solid. That last part continues to blink for several minutes. Again, you know that charging is occurring if one of the battery charge level lamps is flashing white.
Note that during the charge cycle, part of the gauge is dark (top most portion). This lets you know about how much more the battery must charge before reaching fullness.
The battery recharge cycle finishes when the entire battery status gauge goes dark, as we see above. Thus, the battery is no longer charging when all lamps are OFF. Even with the AC charger still connected, no part of the indicator glows when the battery is full.
When unplugged from the adapter, what was the battery charge level meter becomes the battery charge left meter. The more lights lit, the fuller the battery. The fewer lamps glowing, the less run time left. These lamps show battery status for a brief time after you power up the Charge 5. Or they display it whenever you press any of the buttons. Indeed to save power, this meter goes dark after some seconds. So to see the battery level once more, just press the Volume UP or Volume DOWN button.
The last picture shows the 5 powered ON, with the entire battery meter bar aglow. This means that the battery is between eighty and one hundred percent full.
If you have a smart device running the JBL Portable app, see the battery level there as well. Just pair the 5 with this device and bring up the app on that same device.
Then, once the app detects the 5, it displays the speaker’s Home page as we see next.
The level item we point out with the dark blue arrow. It shows how full the battery in the 5 is. The more of that bar that is green, the fuller the battery.
