Cotton Swabs Dipped in Alcohol Make Laptop and Cell Phone Batteries Last Longer

Geek Tip: Use Q-Tips to Make Your Battery Last Longer

April 13, 2009

From the office of Yes, Really comes this tip for maintaining maximum cell phone and laptop battery life: Real Simple advises you to swipe a cotton swab dipped in alcohol across the battery contacts (make sure it's not dripping with alcohol, I assume).

They say this helps "maintain good battery connections and sustain the charge for a longer time."

Well, hot damn. Anyone ever heard of this? I may have to try it!

Water works as well. I used it a few months ago to clean my fan and battery. Works quite well, but my laptop is a bit iffy.

You're essentially just removing dust and other particles that impede the electrical charge. Rubbing alcohol evaporates very quickly, so no, it won't cause a fire.

But if the battery/device that uses the battery heats up, won't this cause a fire?!!

That tip's been around as long as batteries.

I always wait for someone else to try the advice/tip, so if the device burns out, at least it wasn't mine. Same goes for testing a loved one's recipe.
