Boston-Power isn’t really a household name at this point, but the company has some very cool battery tech that promises to make the battery in your laptop work for three times as long before you need to get a new battery. The average laptop battery starts to storage capacity in only a year, yet the Boston-Power Sonata battery promises to last for 3 years with full charge capacity.

I mentioned in December 2008 that HP would be the first computer maker to offer the Sonata batteries for sale. At the time, HP didn’t offer any pricing information for the upgraded battery packs.

HP has now announced that it is offering the Sonata batteries for sale on its website for $149.99. The battery is available to fit 18 different HP models covering 70% of the HP laptop portfolio. HP talks up how long the batteries are operational, but it fails to mention that the original big feature of the Sonata line was the claim that the battery could charge to most of its capacity in a few minutes. The lack of HP mentioning that as a feature leaves me wondering if Boston-Power found that their recharge speed claims didn’t live up to real world use.
