Mobile Phone That (Almost) Never Dies: SpareOne is a no-frills mobile phone that, if unused, can hold a charge for up to 15 years, according to its manufacturer XPAL Power. What's its power source? This dual-band GSM handset comes with an Energizer Ultimate Lithium L91 battery, but it also works with off-the-shelf AA (Alkaline, NiMH, or Lithium) power sticks. Talk time is ten hours. The price: A very nice $50. Not bad for an emergency backup phone.
