[SOLVED] Alkaline Battery Leakage: Dissolving?

[Pico Rico]

but if the batteries go dead sooner, you will be more likely to replace them before the start to ooze.

Point taken.

Nice to hear when something works out. The AAA lights probably fit in a pocket, easier.

The contact cleaners I've used are solvents that leave no residue. It seems as if cleaners that leave a film, should have another name.

It seems the users who recommend Deoxit at Amazon, use it for potentiometers. I've always found that the no-residue kind works fine for potentiometers.

The NiCad battery pack had leaked KOH into my Isotip. Warm water cleaned up the deposits.

The copper is stained. In this circuit, 0.05 ohm where it makes contact would be too much. Sometimes corroded contacts that are cleaned up, won't work reliably in the future.

I wonder if Deoxit would make sure the stained copper in my Isotip would continue to make good contact.

I have a cordless phone with a headset. If I leave it plugged in a couple of days, the incoming and outgoing sound gets scratchy. If I wipe the plug on my shirt, that fixes it. I wonder if Deoxit would prevent that problem.

It seems like three kinds of cleaners. One has solvents that don't affect metals or plastics and leave no residue. Another has solvents and leaves a film. A third would brighten tarnished copper.

I've read that when power companies connect transmission lines, they don't care if the copper is dull with copper oxide. Dull copper doesn't solder well, but does it add significant resistance to contacts?

Connections usually involve breaking through the surface. Lubricants help break through the surface scum. High current arching also break through, but seem problematic being intermittent.

One doesn't. Thanks for the correction.
