## Customer Reviews

### ⭐⭐⭐⭐⭐ Fits just like the original.

Appears to work as advertised.

### ⭐⭐⭐⭐⭐ Long life
*by J***N on July 28, 2021*

I have an older mega boom three and this battery works perfectly. It charges fast and so far has a long life. I have been using it for a couple weeks

### ⭐ Waste of time and money, this battery fails in a month!
*by N***E on August 15, 2025*

Complete waste of time and money... After installing this just over a month ago, it is now worse off than the Mega Boom 3 battery I replaced. At first it worked great, but this thing literally just sits in my office and failed after a month. I only use to to play music in the office for about half an hour once a week for my staff and ensured that it was fully charged afterwards each time. Now when I start the megaboom 3 it immediately says critical battery and sometimes just shuts right back off... at least the original battery I could play music for 20-30 minutes each time before it shut off and I'd have to recharge it. Don't waste your time and money on this junk... the existing battery you have (even if its basically failing) is better than this thing. What's even worse is after you replace the battery it's no longer waterproof and then your just stuck with a dead speaker.
