[sdiy] DX7 battery replacement help

[Nathan M. Reeves]

you know this is at odds at what i was told once to try and "kick  
start" a dead laptop battery...

the tech told me to put into the freezer for 24 hours and then try  
plugging it in to see if it held charge....

IT didn't work so maybe it was a spoof!

Cheers,

nate
