I recently (today) purchased for about $35(us) equivalent, a cordless drill.
This came with 2 18V batteries, and a charger.
I've now noticed that though it does indeed turn off after about an hour,
it seems to shortly thereafter turn back on, for a minute or two, then off

Anyone have any experience with
gold or gold plated electrical
contacts in saltwater (corrosion,
leaching, etc)?
