SpareOne mobile phone has comes up with a new mobile phone which has a battery life of 15 years. Basically the phone is designed for emergency cases. The good thing about this cell phone is that it won't cost you that much. The phone costs around 50 dollar.
It operates on a single AA battery, and they claim that the phone will remain on for 15 years. Consider buying this phone and throwing it in car's trunk, you never know when you would need it in emergency.
The SpareOne can be programmed for instant access to phone numbers of key contacts, including emergency services in any location.The Phone will also transmits its location automatically and it has a build in torch.
Though i seriously doubt if it has been tested to last so long, i am sure they have not tested it by maintaining it for 15 years, anyhow it is a good gadget and should be in a car trunk.
