HP has branded Boston Power's Sonata batteries under the Enviro name to emphasize the environmental attributes. With a longer-lasting battery, consumers need to upgrade less often, which reduces the number of batteries that need to be recycled, HP said in a statement.

Last year, an HP representative estimated the Enviro line costs about $20 to $30 more than traditional batteries.

For start-up company Boston Power, the product release is a significant milestone.

Company founders started three years ago with a fresh design to improve the performance and environmental sustainability of laptop batteries.

While typical laptop batteries start to lose performance after 100 or 150 charges, Boston Power says that its batteries can be charged 1,000 times and get "like new" performance.

Boston Power also sought to use the environmentally conscious materials, eliminating the use PVC plastic andheavy metals cadmium, arsenic, or mercury in the manufacturing process.

In January, Boston Power raised a series D round of $55 million in capital in a difficult financial environment. It plans to expand its laptop battery manufacturing and move into different product categories, including mobile gadget chargers and transportation.
