Default Lenmar MSCAA battery charger.

David Farber scribbled thus:

This Lenmar MSCAA battery charger has a capacity of up to 4 AA or AAA
NiMH batteries. Recently, the red charging l.e.d. over one of the
cells began blinking shortly after the charge cycle began. I measure
the voltage for that cell while being charged and it was not higher
than the cell itself. I tried different batteries all with the same
result. There was also some burning type smell. I disassembled the
unit and the pc board felt warm under that cell. I used my IR
temperature gun and the smd IC that is adjacent to the positive
charging terminal was about 30 degrees Fahrenheit warmer (130 degrees
and rising) than the other three smd chips for their respective
charging slots. I turned the power off so as not to cause more damage
to the components. I was wondering what this smd component was. I
have not been able to id the number: 4800 on the top line, then
BD4P15 on the bottom line. I figure it's worth a shot to replace it.

Thanks for your reply.


I can't find that number but from the picture it could be a power
fet. A 40v - 1.5a device using the number.


Do you have any idea what would be a suitable replacement?

Thanks for your reply.
