Sony SRS XB13 Battery Indicator

The Sony SRS XB13 battery indicator is a small LED near the bottom of the button panel. This displays battery status. So you can partly tell whether it’s draining or charging, or is very low.  But it neither reads out charging progress, or how much charge is in the speaker. But it does flash when the battery reaches near-dead state. Thus in this post, we describe how to read this battery indicator lamp on the XB13.

Sony SRS XB13 Battery Indicator: How to Read the Light

1. The Light is OFF 

The battery level indicator (CHARGE) lamp is dark in the following situations:

  1. When you power down the XB 13 with no charger connected.
  2. When the charger IS present but the battery finished charging to full, as shown next.  This lamp is OFF in this situation.
  3. And finally, the CHARGE light is OFF when the speaker is ON, but the battery is not low. The lamp is dark as long as the battery does not yet need charging in this case.

2. The Sony XB13 Battery Indicator Light Flashes Orange

With the charger not present, the XB13 powered ON, and the battery very low, the CHARGE light starts blinking orange.  This means that the speaker will soon shut off due to a dead battery. So for continued play, you should put it on the charge soon.

3. Sony SRS XB13 Battery Indicator Lamp Doubles as a Charging Light

The CHARGE lamp glows orange (no flashing) as the XB13 recharges, as shown in the next picture.   On this speaker, this glowing light is the only visual means of knowing that charging is going on.  But it does not display how far along the charging is.

Also note that this light should never flash during charging.  If it does, then either your charger is not functioning well, or your USB cable is bad. Or the speaker itself may be faulty.

4. When the Battery Indicator Goes Out While Charging, Then Charging is Complete

As charging continues, the battery indicator keeps glowing,  But eventually,  recharging finishes. Then the lamp changes to show this.  Specifically, It turns OFF when the speaker is OFF, and stays OFF when the XB13 is ON.

5. The Sony SRS XB13 Battery Indicator Is Not Much of a Charge Remaining Meter

When unplugged from the charger, what was the charging indicator becomes the battery charge left indicator.  Well sort of.  If it is dark when the speaker is ON, then the battery has some time remaining. However you cannot tell how much just by reading this lamp.
