Boston-Power says that it is coming up with a new notebook battery named Sonata. The company claims it is safer, lasts longer and can be charged faster. Although the Sonata will not offer greater energy capacity per use–with a four-hour run time, its performance will be average for the market–the company hopes that the battery’s three-year life span, innovative safeguards, and ability to recharge quickly will help it gain a foothold in the battery market. As opposed to existing notebook batteries, which can take an hour to recharge to 80 percent capacity, the Sonata can reach that same level in just 30 minutes, according to Boston-Power. And whereas current batteries degrade very quickly, permanently losing up to 50 percent of their capacity within months, the Sonata retains up to 80 percent of its capacity over three years.
