Battery operated alarm clocks combine the best of the AC world with the best of the DC world. For the most part, battery operated alarm clocks are powered by the AC current from your mains. Yet, in case of power failure, they switch instantly to battery power. This is especially important during the night. You are counting on your alarm clock to wake you up on time and with a battery backup this will still happen even with the loss of power in the house. A clock that works like that is called a battery backup alarm clock. In this article we will review two battery operated alarm clocks, Sony ICF-C318 and Sharp SPC019F. By reading through you will know whether a battery operated alarm clock is something that would be suitable for your home.

Sony ICF-C318 Automatic Time Set Clock with Dual Alarm (Black). This clock's call to fame is that it comes with its time factory pre-set. No wonder as it is indeed a battery backed up clock. All you have to do when you receive it is change the time zone and plug it in. If your time zone is EST, you are all set as is. This battery operated dual alarm clock features dual alarms, which will enable two people (him and her) to use the same alarm clock to wake up at two different times. The alarm clock features a well-lit 0.9 inch green color LED display. The AM/FM battery operated clock radio included is adequate for casual listening and to wake you up in the morning. The reception is superb. The clock has a built-in calendar. As with many Sony products, the placement of buttons on the Sony battery alarm clocks is highly intuitive, so you may not need to read the manual to operate the alarm clock. The LED light brightness can be adjusted with three levels for those of us who need maximum darkness in the room to be able to sleep. The buzzer volume has two levels of volume. Plus, as stated, if the buzzer is still not loud enough for you, you can set up the radio to wake you up.

Sharp SPC019F Red LED Alarm Clock with a Wedge Style Case (Silver/Blue). This battery operated alarm clock features a silver and titanium color combination and a modern geometry which will both add flair to your bedside table. The control settings are conveniently placed on the front top of the curvy shaped encasing. The features are standard for the modern alarm clock: snooze, calendar, temperature reading in degrees Celsius or Fahrenheit. As per customers feedback, the modern looks of the alarm clock are much better when delivered to your home. They can not adequately be represented in an online image. Other customers who considered themselves technically challenged, found Sharp SPC019F easy to operate and its large, 0.9 inch LED display easy to read.
