I hope you had a relaxing holiday break. I know that our house has been invaded by all sorts of buzzing, flashing, and really noisy toys. And you know what all those toys have in common? Batteries.
Did you know that most devices will stop working whenever the juice in its batteries fall by just 20%?
I’m not sure I believe it but…
… I learned about a little startup that had a product called Batteriser. They make a sleeve that goes around a battery and helps you get the remaining 80%. It’s “still in development” and I’m eager to see their progress but like a lot of folks I’m skeptical (very skeptical).
Not all batteries discharge equally!
It might surprise you to learn that when your device is “out of juice,” it doesn’t mean every battery is completely consumed. Test each one to find out which one is the low man on the totem pole, then just replace him.
You’ll need a battery tester. You can get one designed to test batteries (it’s only $7) or get a multimeter (costs about $10 more) which will let you test a variety of things (current, voltage, resistance, etc.) across two points.
