How Long Does the JBL Xtreme 2 Battery Last

Answers the question: How long does the JBL Xtreme 2 battery last? The 10,000 mAh battery inside this speaker is a lithium polymer device, that follows roughly guessable life cycle patterns as long as you avoid storing the speaker in extreme environments.





How Long Does the JBL Xtreme 2 Battery Last ?

As far as how long the battery will last per charge, you can get a rough idea of how much more the JBL Xtreme 2 will play before needing a full charge, by looking at the battery meter lamps on the front bottom panel.

When the speaker is ON, the meter lights show if the battery is on the verge of running out of energy. Now when the battery is full, all the lamps on the meter light up a solid white.  As the battery charge is used up, the lamps begin going out, one by one, starting first at the far right, and progressing left.  Then when the speaker gets very low, the last light on the battery gauge starts blinking red.

See the meter showing a one hundred percent full battery in the next picture. Note the gauge, pointed out with the green arrow, with all five of its lamps glowing.

Now when the speaker is new, and using the included 19 volt AC charger, the time it takes to fully charge this speaker  is about 3.5 hours.  And, the full battery should last for around fifteen hours of play time before dying.





How Long Does the JBL Xtreme 2 Battery Last Over Time ?

Typically, this battery gradually loses its ability to charge.  So a sign of a battery that is nearing the end of life, is that it goes dead much faster than fifteen hours, or takes too little or too much time to fully recharge. So if you fully juice your speaker, but it only plays for under twelve hours before going dead, its battery may be degrading, and is thus, no longer able to hold a full charge.

Now this sort of battery accepts between 500 and 1,000 charge / discharge cycles before showing charge degradation. So if you charge your speaker once a week, you can expect its battery to last around ten years.  If you recharge it four times per week, then the battery would last around two and a half years.

Remember though that environmental factors such as how warm or cold the area is where you keep the speaker, can affect these numbers.  So, an exact predictions of how long the JBL Xtreme 2 battery will last is likely not possible. But you can guess at it with reasonable accuracy.
