The Charge 2 Plus JBL speaker has a group of LEDs in its buttons panel on the top of the speaker, as we show in the pictures that follow. These display battery fullness and charging status. In brief, the JBL Charge 2 Plus battery indicator lets you see charging progress, and how full the battery is when not recharging.
How to Read the JBL Charge 2 Plus Battery Indicator
1. All Lamps OFF
When you power down the Charge 2 Plus with no charger connected, no lamps light up. The lamps also all show dark, as we see next, when the charger IS connected but the battery finished charging to full.

2. JBL Charge 2 Plus Battery Indicator Shows Battery Recharging Progress
There are five lamps that light in succession as the speaker battery charging advances, as shown in the next picture.

This speaker is charging when you see one of these lamps blinking white. When the battery is completely depleted, the light on the far right blinks white while charging. Then as charging continues, that lamp stops flashing, and assumes a steady white glow. Then, the next lamp to the left starts blinking white as the battery fills.
Note though, that you may see the first lamp (far right) blink red. This does not mean that charging is proceeding. Instead, it means that the speaker battery is quite low, nearly dead, and should be recharged right away. It only flashes red when the battery is almost dead and AC power has not yet flowing to the speaker. When you connect power though, this red flashing light begins blinking white. Remember. This light never flashes red while charging is going on.
3. When All Lamps Light Up Solid, Charging is Complete
As speaker charging advances, more and more of the lamps on the JBL Charge 2 Plus battery indicator light up solid, That is, the flashing LED moves further and further along, until that blinking reaches the last of these five lamps.
Battery charging is about done when all but the last of the battery status lights light solid. The last one continues to blink for several minutes. Again, you know that charging is happening if one of the battery charge level lamps is flashing white.
The last picture above shows the speaker just before completing a full charge cycle. Note that all the lamps in the battery status meter are glowing. However, the last one continues to blink.
The battery recharge cycle finishes when all battery status indicator lights turn off. Thus, the battery is no longer charging when all lamps are OFF. Even with the AC charger still connected, no lamp glows when battery is full.
4. The JBL Charge 2 Plus Battery Indicator Also Shows Battery Fullness when Not Charging
When unplugged from the charger, what was the charging indicator becomes the battery level indicator. The more lights lit, the fuller the battery. The fewer glowing lamps, the less speaker run time is left. These lamps show battery status for a brief time after you power up the Charge 2 Plus, or whenever you press any of the buttons. To save power, these lamps go dark after some seconds. So to see the battery charge remaining indication once more, just press the volume UP or DOWN buttons to bring the lamps back to life.
Finally, when the battery reaches critically low levels, the rightmost lamp in the battery indicator gauge begins flashing red any time the speaker is ON.
