Lithium AA batteries - I’m a fan

I love gadgets that reduce the complexity and overhead of my life. I don’t need any more “scenarios enabled” - except the scenario of “reduce the amount of maintenance in my life.”

It’s one reason why I’m glad my car uses synthetic motor oil, even though it costs dramatically more. Fewer trips for service!

Here’s something I’m a big fan of right now: Lithium AA batteries!

Now, there’s nothing new about lithium batteries - they’ve always been around for cameras. But they were always super pricey and… well… that funny size for cameras.

Now Energizer is selling lithium batteries in the AA (and AAA) format. They’re still pretty pricey at nearly $2 per battery, but the longevity and shelf life is awesome. You can find them at Target, Walmart, etc. Here are some of the places I use them:

• the Microsoft Wireless Mouse that I keep in my backpack all the time. There’s nothing worse than pulling out the mouse, and finding that its battery is dead. And now, this model of mouse has awesome power management so it lasts even longer. Double sweet!
• my travel electric toothbrush.
• my travel oral irrigator. (I’m somewhat paranoid of having cavities…)
• my awesomely bright flashlight.

Another positive of these batteries is that they’re lighter than regular AA batteries. Sure it’s not significant, but every bit adds up when you’re traveling!
