Retro Repair - Repairing a leaked battery in the Amiga 2000

Greetings everone,

Ide like to report here about our small, ongoing journey about repairing the Amiga 2000 Mainboard from a leaking battery.
Let that said we are not even Semi Professional soldering people. We are hobbyists trying to save Old Hardware from dieing.
We sure are open to any hints you can give us.

We recently aquired a Amiga 2000 knowing it has a leacking battery and most likley damaging this machine for many manny Years.

Knowing that a big chunk of work awaits we decided to give it a go.
We made a Video of the first First Aid Actions we took cus of the Battery Leackage.

As you can see we stopped where we neutralized the most of the alkaline. (I know i say Acid in the video but thats a german thing, its called "Batterie säure" in german wich is translated as Battery Acid)


We no released Part Two if this Jurney:

The Alkaline transformed the Solder into potassium stannate that was Resistant to any Heat we applyd (up to 450 C) and making unsolder the Attacked parts really hard.



As you can see the Shiny solder turned into some Grey matter

Now we scrubbed up the solder mask with a special brush made out of fiberglass to take away all the damaged coating.


The damage of the Battery Liquid was crawling all trhough the CPU socket. As you can see a few traces got lost in the process as they where too damaged


We now replaced also attacked Capacitors and joined ...not really professionally but working, the traces with a wire together.



And what can i say itall worked out as oyu can see in the video! The Amiga is now back up and runs smoothley!
