Can I charge à rechargable battery directly from à power source?

Can i charge à rechargable battery directly from à power source without going throughout à charger?

I have bluetooth speaker which is charger using à mini USB port. The USB plug has been destroyed and is no longer usable. Taling the speaker apart I can see where the battery attaches to the PC board. If I 'tap in' to the wires going from the battery to the board and attach a 5V 1A power source, everything seems to work OK. Also, it appears as though the battery charges up.

I could simply cut the battery wires and run the speaker directly from the power block. The question is, if I keep the battery connected will it overcharge and cause problems (such as overheating and catching fire)?

I would reccomend NOT directly connecting the battery, as you are risking the battery exploding, which can cause damage.

Not really, LiOn batteries need a stepped charge and the logic to control this is part of the device and/or the charger, how about fixing the USB socket.

Thanks, Dan. That's pretty much what I figured. I will cut the battery wires and run it directly from the block charger.

As for fixing the USB port, that is beyond my capabilities. Even if I could find exactly the right replacement part, unsoldering and then resoldering the microscopic surface-mount pins is way out of my wheelhouse. Replacing large caps on a motherboard is more my speed.
