Chosen Solution

Hi there! I have the UE Megaboom and it doesn’t charge at all. Currently, it only turns on when it is connected via charger. Whenever i turn it on when its connected, and press the + and - buttons simultaneously to check the charge, it keeps saying its 40%. Also the charger LED does not turn on at all when connected. I know the LED itself is not blown as it was charging after some fluke but now its back to being turned off. I have tried the following:

  1. pressing all combinations of the buttons (i.e. bluetooth, power, + and - in pairs, triples or all 4), (power&- for 10s resets after sound but still cant turn on without charger)
  2. Trying a new battery. (When there was no battery connected in the speaker and it was also connected by a charger, the LED light was flashing but when the battery was connected it stopped working once again) This is the battery replacement i used: https://www.ebay.com.au/itm/3400mAh-25-1…
  3. Repeatedly plug and unplug charger for short cycles ~5s(charger connected)/~2s (charged disconnected) for 5-10mins and then leaving to charge for many minutes. I have access to 2 chargers on which is quick charger QC 3.0 with 5V & 3A and laptop charger with 5.1V * 1A. I had brief progress today when i did step 3. with the QC 3.0 charger and then connecting the megaboom to the laptop charger after all those cycles. It then momentarily lit up the white charger light for 2-5s but then turned off. Im running firmware version 2.2.9. Any help will be appreciated. P.S: I can’t avail my warranty as it’s past it. I already contacted Logitech recently and they said since i replaced the battery they wouldn’t give me any support.

Hello, I think you have to problem in the charging circuit, and it can be a simple diode that prevent the current to go from the battery to the charger which is bad, if you have used your UE Megaboom in the bathroom or in a place where there is lot of humidity then the electronic board inside it can be shorted, try to clean it maybe that will solve your problem. Good luck ;).

Battery connection is poor. Have found this with heaps of my ones. Popped off charging board..complete with plastic surround. Wedged some rolled up paper on one side of battery to shim it on an angle. Had to lever battery with a flat blade screwdriver to allow gap to fit paper roll between the silicon and battery. Carefully aligned pins and put charging cap back on. I hope this helps others.. as it done my head in for ages trying to find issue.

I’ve been trying to fix it about 4 years. It’s a intermittent failure. I’m so disappointed , because I really like the speaker when it works…

Had an issue where my speaker would not charge at all no matter what I tried after a few attempts to contact Ultimate ears with no response by the way I did some digging online and found a fix of holding down the power, volume up and volume down buttons to do a factory reset it started charging again pleased it’s fixed but would never recommend this product or any products by the company hopefully this may help some of you out there!

What a bunch of Logitech MutherFUVKERS.that have me a lot of hope.Somuch for customer service.
