I think I revived my Futaba PCM 1024 battery

Not completely sure, but after three charge/discharge cycles it was holding strong. Discharged again, now charging the recommended 15 hours. Wonder how my old stick packs will fare....should probably be working on the chassis but have my geek on so playing with batteries now (just replaced my iPod Classic battery while cleaning the PCM)...

Ni-Cads die hard.
I have a bunch of old Sanyo and Panasonic cells and they all holds and takes a charge.
3 secs directly in parallel on ONE of the 12V batteries on my Toyota, brings them back to live.
But mind You, it must be from a TOYOTA

So, remember often charge.
