At least one of the battery status lamps lights up on the speaker when you apply sufficient USB power. There are five lamps on this speaker that light in succession as internal battery charging progresses, as shown in the next picture.

6. Allow the Speaker to Charge Until All Battery Power Lights Go Off

Battery charging is almost complete when all but the last of the battery status lights light solid. The last one continues to blink for several minutes more to top off the charging.

Then, the battery recharge cycle finishes when all battery status gauge lights go out, as shown next.

8. Fully Close the Waterproof Port Door to Continue with How to Charge the JBL Charge 3

Note that unless this flap is snapped securely and completely in place, water could enter the port area, possibly damaging the electronics inside the speaker. So, be careful to press the port door closed with enough force to correctly seat it, to get full water resistance.  See how this port door looks when completely closed and sealed in the next picture.

9. Done with How to Charge the JBL Charge 3 !

We have now fully charged our speaker. Note that the battery charge status gauge just after turning on the speaker after a full recharge. All lamps that make up the gauge glow, meaning that the speaker is current fully charged.

Finally, repeat this process every ten to twelve hours of music play through the Charge 3, to keep its battery in top working order. We charge ours when the battery indicator lights show only one light glowing.
