How To Know When a JBL Speaker is Fully Charged? (All Models)

How To Know When JBL Speakers are Fully Charged?

To know when a JBL Speaker is fully charged, check the battery indicator LED Lights. For JBL Flip 4 and older models, check the 5 LED lights under the speaker. Each LED light powered up indicated 20% of charge.

For the latest JBL Speakers models (JBL Flip 5-6), check the straight white battery indicator light (located next to the charging port) to know how much battery the speaker has left. The more the battery indicator light is filled with a white color, the more charge the speaker has left. For instance, if the battery indicator light is half-filled with a white color, the battery has 50% of charge.

How Long Does it Take For JBL Speakers To Fully Charge?

The time it takes JBL Speakers to fully charge depends on the model as each of them has different battery capacities. The larger the battery capacity (mAh) the longer it takes JBL Speakers to charge, but it also keeps the charger for a longer time.

Here’s a list of all JBL Speakers and their charging time:

  • JBL Flip 1 – 3 Hours to Fully Charge
  • JBL Flip 2 – The JBL Flip 2 comes with a 2000mAh Li-Ion polymer battery and it takes 3 hours to fully charge.
  • JBL Flip 3 – The JBL Flip 3 comes with a 3000mAh Li-ion polymer battery and it takes 3.5 hours to fully charge.
  • JBL Flip 4 – The JBL Flip 4 comes with a 3000mAh Li-ion polymer battery and it takes 3.5 hours to fully charge.
  • JBL Flip 5 – The JBL Flip 5 has a 4800mAh Li-ion polymer battery and it takes 2.5 hours to fully charge.
  • JBL Flip 6 – The JBL Flip 6 is equipped with a 4800mAh Lithium polymer battery and it takes 2.5 hours to fully charge.
  • JBL GO 1 – The JBL GO 1 has a 600mAh lithium polymer battery and takes 1.5 hours to fully charge.
  • JBL GO 2 – The JBL Go 2 comes with a 730mAh Lithium-ion polymer battery that takes 2.5 hours to fully charge.

The charge time of the JBL Speaker also depends on how many charging cycles its battery (Lithium-ion Polymer) has completed. Lithium-ion polymer batteries come with a certain number of charging cycles, 300-500.

The exact number of charging cycles for a battery depends on the depth of discharge (DoD), charging voltage and current, charge-discharge cycling frequency, and manufacturer quality. A (1) charging cycle is completed once the battery level goes from full to empty (100-0%) and back to 100%.

The performance and capacity of a lithium-ion battery will decrease once it completes its charging cycles. The battery doesn’t stop working when the charging cycles are completed, instead, its capacity decreases gradually over time. This means the battery will take longer to charge and keep its charge for less time.

How To Know How Much Charge a JBL Speaker Has Left?

To know how much charge a JBL Speaker has left, check the battery indicator LED lights. Older models of JBL Flip (Flip 2-4) have 5 battery light LED lights that each indicate 20% of charge. While the latest models (JBL Flip 5-6) have a straight white battery indicator LED that indicates the battery level.

In the older models of JBL Flip speakers, each LED light turned on indicated a 20% of charge. For instance, if three (3) LED lights (battery indicator) are powered up, the speaker has approximately 60% of the charge left.

In the newer models (JBL Flip 5-6), the battery indicator LED light (a straight light located next to the charging port) indicates how much charge is left by filling the battery indicator with a white color. For instance, if the battery indicator is half-filled with white light, the speaker has approximately 50% left of charge.

The LED battery indicator lights aren’t always activated, press any of the buttons once to activate them.

For JBL GO portable speakers there’s no way to know the exact battery charge level. However, if the power button is blinking a red color, the battery is low and requires charging.

Understanding The JBL Speakers LED Indicators

The only way to know if the battery is low or if something is wrong is to check the LED indicators. Most JBL speakers come with the same indicators (except for the GO models). Different LED lights will light up for different things, LED lights will also light up in different colors.

Here is a list of JBL Speakers LED Lights and their meaning:

  • 1st LED Light Steady Red – JBL Speaker is at low battery charge (1-20%) and needs charging.
  • 2nd LED Light Steady Blue – JBL Speaker is at low battery charge (20-40%) and needs charging.
  • 3rd LED Light Steady Blue – JBL Speaker is at a medium charge (40-60%).
  • 4th LED Light Steady Blue – JBL Speaker is at 60-80% charge.
  • 5th LED Light Steady Blue – JBL Speaker is at 80-100% charge.

When all 5 LED lights have a steady blue color, it means the JBL speaker is fully charged. If the LED lights are flashing, it means the speaker is being charged. You should wait until all 5 LED lights have a steady blue color before you remove the charger.

These are the LED light indicators for JBL Speaker 1-5. However, the portable JBL GO speaker (1&2) doesn’t come with 5 LED lights, instead, it comes with 1 LED at the top of the speaker.

The LED lights of the JBL GO flashes different colors, here’s what they mean:

  • LED Light Flashing Red – The JBL Portable Speaker is at low battery charge and needs charging
  • LED Light Steady Red – The JBL Portable Speaker is charging.
  • The LED Light Turned OFF – The JBL Portable Speaker is fully charged.

The single LED light will show you when the battery of the JBL GO speaker is low or fully charged. The LED light will flash red when the battery is low. When you connect the JBL Go speaker to a power source, the LED light will show a steady red color, and when the JBL Go speaker is fully charged the LED light will turn off.
