Ever had a dead car battery, reach for your cellphone to call for help, and find that your cellphone’s battery is dead, too? If you kept a SpareOne cellphone in your car or purse for emergencies, you wouldn’t have to worry about that scenario. The SpareOne is a Dual band GSM phone with patented technology that allows it to be powered by a single alkaline, NiMH, or lithium AA battery – the most widely-available battery. When powered with an Energizer Ultimate Lithium AA battery (included), you’ll have 10 hours of talk time, and it can keep its charge up to 15 years when unused. The SpareOne is a very reliable phone to leave in your car for emergencies and as a means of keeping in touch with your children or older relatives. SpareOne, equipped with an Energizer Ultimate Lithium battery and a micro SIM card, will be available in Q1 2012 in the US for $49.99. Different versions (US, Europe, and Asia) will be available with WCDMA frequency options for selected regions. It will also soon be available in customizable versions for businesses, events, and other uses.
