JBL Xtreme 1 Charging Indicator

The JBL Xtreme 1 has a row of LEDs across its lower front panel. These display battery fullness and charging status. In short, the JBL Xtreme 1 Charging Indicator lets you see charging progress. Then when not charging, it shows how full the battery is. We explain how to read this meter next.

JBL Xtreme 1 Charging Indicator: How to Read It

1. All LEDs OFF

When you power down the JBL Xtreme 1 with no charger connected, no lamps glow, as shown next.  The lamps also all show dark when the charger IS present but the battery finished charging.

2. JBL Xtreme 1 Charging Indicator: Shows 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 almost dead, the light on the far left blinks red. Then it flashes white once you begin charging.  Then as charging continues, that lamp stops flashing, and assumes a steady white glow.  At that point, the next lamp to the right starts blinking white.

3. When All Lamps Light Up Solid, Charging is About Done

As speaker charging progresses, more of the lamps light up solid. That is, the flashing white LED moves further to the right, until that blinking reaches the last lamp.

Battery charging is about complete when all but the last of the Charging Indicator lamps light solid.  The last one continues to blink for several minutes.  Again, you know that charging is occurring if one of the charge level lamps is flashing white.

The battery recharge cycle finishes when all indicator lights turn off, as shown next. 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 Xtreme 1 Charging Indicator also Shows Battery Fullness when Not Charging

When you disconnect the charger, what was the charging indicator becomes the Charging Indicator.  The more lights that glow, the fuller the battery. The fewer glowing lamps, the less speaker run time remains.

Now these lamps show battery status for a brief time after speaker power up. And they also display it whenever you press either of the volume buttons.  To save power, these lamps go dark after some seconds.  So to see how much battery charge remains,  press the volume UP or DOWN buttons.
