Hi, When I'm watching tv sometimes the remote has a little more life before a battery change by banging it lightly on the coffee table. It has a few more last gasps. What is taking place? Is it the acid or paste being activated by (pressure) to squeeze out a few more electrons or is it a slight oxidation on the cell terminals reducing voltage/ Or is it something else......whats your take....Mark...I know this is an audio forum but I'm curious about interconnects and passive preamps and this question came to mind...thanks people...Mark Korda

my guess is that you're knocking some oxidation products off the terminals and improving the contact.

I think part of it could be terminal contact oxidation because I can sometimes get a remote to work by spinning the batteries around their axis (and burnishing the contacts), without any real pressure or shock to the batteries.  Maybe banging it does a bit of both, as "stimulating" the electrolyte seems plausible, too.

Stimulating the Electrolyte would be a great name for a rock band.

This is what's happening, I can spin batteries in my remote or mouse or keyboard or ... and always get more out of them. Clean the connection, get more life.

Hi, I'm not sure I got the right forum. I've seemed to have got the cast from Seinfeld. Good stuff! Keep it coming....Mark.

Jerry (in high-pitched whining voice):  "What's the deal with batteries?"

George:  "Jerry, no!"

Battery Nazi:  "No juice for you!"

From a technical standpoint, when the batteries are already nearly spent, it takes almost no resistance to create enough voltage drop in the circuit cause the regulator to drop out and then remote quits functioning.
