Default Re: PYE PF1 battery refurbishment?

Many of the yellow batteries were that bad by the 1980s. Yours has had almost another 40years!

Good luck with modern PP3 I think you mean.

I don't like what is available today since they are all NiMh and exhibit self discharge and high internal resistance. I have a Motorola GP300 that just wouldn't work on NiMh. TX currrent would drop the terminal Voltage activating the battery alarm no matter how freshly charged the pack. I rebuilt it a second time with NiCd and now no problem.

Hopefully the Burndept won't be that fussy.
