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.
huh turns out the 1306 4.5V cell is just three 1.5V batteries in a trench coat
@tubetime Always has been.

@RueNahcMohr @tubetime ive Always wondered, how did it come down to this?

To the point it's cheaper to manufacture 3x1.5v cells in a specialized format, instead of just doing the whole 4.5v pack

@ozone89 @tubetime

its just mass manufacturing math.
