Battery Alarm Clocks – Mobile time keepers
There are many cases when you don’t have access to power so battery alarm clocks fit the bill nicely. Once upon a time, long ago you would have to wind up a clock if you did not want to plug it in. If you forgot to wind it, oh well, you were late for work.
Winding the clock was not the only thing that drove people crazy. Some of these clocks would make an insanely loud ticking noise.
Anyway, those days are over and you can get a clock with all the features you could ever want and everything is portable because all you need is one battery.
The new clocks are also very energy efficient so replacing batteries is not done very often at all.
So what types of battery alarm clocks are available now? Well, there are many styles to choose from. The first and probably most recognizable style is the old round clock with the two large brass bells on top.
The nice thing about this new clock is the fact that it is quiet. The solid state movement makes absolutely no noise so you only get noise when you want it. The bells ring just like the old style clocks. If you want to get away from the original style alarm clock, then there are all sorts of alternatives.
As far as solid state displays goes, there are LED clocks and LCD clocks. LED stands for light emitting diode and you cannot miss it.
They come in bright red or green or amber colors and must be plugged in because LED clocks consume too much power to be really useful as battery powered devices. LCD stands for liquid crystal display and LCD displays are very efficient power-wise.
The only time you use a significant amount of power is turning on the backlight when it is dark out. The drawback is that you cannot see an LCD display in the dark without a light source.
There are lots of other features that modern battery alarm clocks have such as temperature readouts, automatic time adjustment with built in radio receivers and other goodies.
