Good day, everyone.
Because it had a built-in 3.7v battery, my Bluetooth speaker died and ceased working.
The speaker does not work on its own when plugged in, indicating that the battery is dead.
I went out and got a 4.2v battery to replace it. The initial battery charge worked and kept the speaker operating for a while until it ran out of juice, at which point I attempted to charge it using the USB connector suggested for charging, but it didn't work.
According to the merchant where I purchased the battery, switching between voltages should not be a problem, but it appears to be. Is there a workaround for this?
