19th Century invention

Without the invention of the battery, I'm not too sure how today's life would be able to work the way it does.
Without the battery, I wouldn't wake up to an alarm clock every morning. Without my alarm clock I'm always too tired to wake up. We wouldn't be able to tell time the way we do, for that matter. Cd players wouldn't be able to work away from an outlet. Pretty much anything that is electrical would not exist, or would but without efficiency.
Although, hindsight kind of makes me wish the battery wasn't invented. Without my alarm clock maybe my sleeping patterns would be more steady, causing less health problems. Maybe without the option of meesing around with technology for hours on end would increase work and production. Maybe the ideal of things being "easier" for us only caused prolonged hardship. I guess what I mean to say is the idea of living without the power of a battery is unimaginable, and maybe that isn't such a good thing that we have something so easy to take for granted.
