PowerBook 500 series battery rebuild with "X"

[AlpineRaven]

Good morning all, 

PowerBook 5x0 series battery rebuild/recell

Is the battery bricked if they show "X" on the icon in finder?

This is the 2nd battery I've tried rebuilding the pack and it still shows X and I seem cannot get the battery charged up or recognised - what am I doing wrong? 

So far I've tried;

Emmpathy
Lind Battery Utility BU 500 Deluxe
Zap the pram
Reset the PMU





Neither can get the battery working again? The batteries are fully charged/ready to go

Cheers

AP

Pay attention to Equill's comments, by the way, as he was very knowledgable and generally is a fund of helpful information.
