Q: Can I leave my speaker plugged into the mains charger constantly with this new Teufel BOOMSTER 2020 battery installed?
Yes, you can. Our replacement battery for the Teufel BOOMSTER 2020 speaker features an intelligent built-in circuit board with overcharge and overheating protection. Once the cells reach 100% capacity, the power management system automatically cuts off the charging current. However, to preserve the maximum lifespan of lithium-ion cells, we recommend running the speaker on battery power down to about 20% at least once a month rather than keeping it permanently plugged in.
Q: Will this battery fit perfectly inside my Teufel BOOMSTER 2020 speaker compartment, and how is the playtime?
Yes, it is guaranteed to fit precisely. This battery is engineered strictly to OEM (Original Equipment Manufacturer) specifications, meaning the physical dimensions, internal wiring, and connector plug match your original Teufel BOOMSTER 2020 battery exactly. Assembled using premium Grade-A+ cells, it delivers a stable voltage output even at maximum speaker volume, providing identical or superior playtime compared to your original battery when it was brand new.
