HP has launched a new Long Life Battery for its commercial notebook PCs. HP claims that the new batteries provide customers with increased battery lifespan and reduced cost of ownership versus standard batteries.

Based on Boston-Power’s Sonata Lithium-ion (Li-ion) battery cell technology, the HP Long Life Battery can be charged over 1,000 times before the battery’s capacity begins to noticeably degrade, the company said. Additionally, the battery can be charged to 90% of its capacity in 90 minutes, which is useful for travellers who only have a limited amount of time near an electric outlet.

According to HP, the new battery also offers environmental benefits as the need to replace batteries less frequently means that fewer batteries need disposal and fill up landfills.

Christina Lampe-Onnerud, founder and CEO of Boston-Power, said: “From the beginning, our goal has been to help notebook computer users benefit from optimal mobility with dependable, high-performance, environmentally sustainable batteries. HP’s endorsement of Sonata is a great step forward in popularising this battery technology.”

HP said that its customers with compatible notebooks can purchase Sonata-powered batteries to replace their existing batteries or use as a spare on long trips or plane flights. No system changes are required.

The HP Long Life Battery is reportedly available as an accessory throughout EMEA, from September 1, 2009 at a recommended street price starting at €139. It supports the HP EliteBook 6930p and HP Compaq’s 6730b, 6530b and 6735b Notebook PCs. It will also be available on future selected commercial and consumer notebook PCs.
