Keep Extra Batteries

One of the things that I hate the most about modern electronic gadgets is their replacement batteries. While some devices use standard batteries, most use a proprietary battery that can only be used in that device. This means that it’s hard to find the right kind of battery right when you need it. That’s really a bummer, but it can be mitigated if you keep a spare battery on hand. I know that’s kind of overkill, but sometimes you have to do it.
