latest pickup: a very obscure Microsoft product -- the PCjr BOOSTER!
the battery is very nasty indeed. it needs to come out and i need to remove the corrosion on the holder.
it's a NEDA 1306A cell! 4.5V.
green fuzz!
you can see the leaked alkaline chemical react with the vinegar here.
@tubetime does this clean/fix the holder contacts? I usually just try scraping them and spraying basic household cleaner, but maybe your way is better, yes?
@zackstern @tubetime this is much better than scraping. You may need to brush off left over residue though. This completely neutralizes the base residue and stops any further damage.
