What every best cordless phone has

  • Today's cordless phones are smaller than they used to be, though larger than cell phones, making them easy to carry around but more difficult to cradle on your shoulder. Remember that smaller phones also have smaller keypad buttons, which can make dialing difficult. Some cordless phones include a headset jack for hands-free use, but you'll most likely have to supply your own headset, which will cost you $10 to $30.
  • Minimal interference: You'll rarely see 2.4 GHz and 5.8 GHz phones on store shelves. Phones that operate on the 1.9 GHz frequency (DECT) are the least susceptible to interference, and they no longer cost more than older-style phones. If you live in an apartment building or other populous area, keep in mind that you may get interference from wireless networks even if you don't have one yourself.
  • Compatibility with caller ID and as speakerphones: Most new models are also expandable to include more handsets. Some have headphone jacks and belt clips for hands-free use.
  • Batteries that last from one to two years, depending on use: Some phones use proprietary battery packs, which can only accept direct replacements. Others use universal cordless-phone batteries that you can find at Radio Shack and other stores.
  • Don't place the handset of a cordless phone back on its base after each call, experts say. Charging the battery too frequently will weaken its power and shorten its life.
