|Hitachi DRC-10K... Slightly used, like 30 years|
|B-2 type power pack (once opened)|
|Six new NiMh cells soldered together|
|Heatshrink protecting joints|
After opening the power pack you'll need to unsolder the power wires from old batteries and start preparing the new ones. First duplicate the layout of the batteries and solder metal tabs together. As these differ for each pack I can't give more explicit guide here. Just be sure to check polarities and cnnect the batteries just like old ones were and it will be ok.

Next is soldering the power connector wires to batteries (remember polarity) and stuffing these renewed innards inside existing power pack enclosure. I decided to use some hot glue to keep power pack safely closed.

|Old NiCd batteries I've used years ago|
And that leaves the last part, trash disposal. Making sure that those old used NiCd batteries I had used years ago at previous Rebuild will be properly handled and processed as an special garbage. I have no idea how harmful NiCd batteries really are, but at least in EU area those are under strict control, so one has to be careful how to dispose them.
I know... I have not been making these updates as often I ought to, for keeping this blog interesting. So sorry, not having any good excuses either, no mystic NDA projects, no family issues etcetc..
