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. ## Frequently Bought Together - Replacement Battery for Ultimate Ears MEGABOOM 3 Wireless Bluetooth Speaker, fits Part no 533-000146 - QJYTH Cord Replacement for UE Boom Charger, 1.2m USB Charging Cable Compatible with Logitech Ultimate Ears Boom 3/ MEGABOOM 3/ UE Wonderboom/UE Boom/Megaboom/Mega Boom (1 Pack, White) - Sqrmekoko Quick Charger Cable Adapter Compatible with Ultimate Ears UE Boom MEGABOOM Wireless Speaker White & Yellow --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/312772539-replacement-battery-for-logitech-ue-megaboom-3-s-00147-984](https://www.desertcart.pl/products/312772539-replacement-battery-for-logitech-ue-megaboom-3-s-00147-984) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-25*
