Wish I knew who could fix the battery pack.

You can fix the battery pack yourself. I fixed mine using just an X-Acto knife, 4 1/3 AAA batteries and some soldering. Use this guide but install 4 1/3 AAA batteries in series instead of the weird ones, wih the same orientation of the original ones.

Also you can buy a replacement pack from the same site that performs the repairs for 35 €.

I have quite a bit of corrosion that I believe i can get rid of. I will take it apart and try to see if i can clean it up. I've never seen 1/3 AAA batteries before. I'll have to look at that on Google...

WOW never knew they existed!

If I can't get rid of the corrosion I will just buy a pack.
