Fit properly. Much cheaper than a replacement Boom3. ### ⭐⭐⭐⭐⭐ Works well, UE Boom 2 is alive again! *by on Reviewed in the United States April 24, 2025* My UE Boom 2 would no longer hold charge. I followed the instructions on youTube to replace the battery, and it took maybe 15 minutes. The old battery had foam around it to make the fit more snug than this one, but it peeled off and I was able to stick it to the replacement. So far it charged up and ran for about an hour in initial testing. If I don't update the review, then it's all good! ### ⭐⭐⭐⭐⭐ Perfect fit *by on Reviewed in the United States July 22, 2024* It was a very easy battery swap on my Ultimate Ears Boom speaker. I did not use the included tools, I used a screwdriver based on another review. Based on the amount of leverage required with a standard steel screwdriver, I doubt the plastic tools would hold up. Once apart, the battery is right there. Popped out the old and put in the new one…PRESTO!! The battery had an 80% charge from the factory. It’s good as new! ## Frequently Bought Together - MPF Products 3400mAh Extended T123682016VK Battery Replacement Compatible with Logitech Ultimate Ears UE Boom 3 Wireless Waterproof Bluetooth Speaker - Replacement Battery for Logitech UE MegaBoom Compatible with S-00147 984-001362 084-000845 Ultimate Ears Megaboom 3 Megaboom 3 S-00171 fits Part No Logitech 533-000116, 533-000138,7.4V Li-ion --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/332519645-3400mah-extended-t123682016vk-battery-replacement-compatible-with-logitech-ultimate-ears](https://www.desertcart.pt/products/332519645-3400mah-extended-t123682016vk-battery-replacement-compatible-with-logitech-ultimate-ears) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-06*
