Boston Power Inc created these lithium ion batteries, apparently what they do is act like new for up to 3 years. That and they will charge to full capacity in 30 minutes while delivering longer, on average, run-times. The batteries will provide 4.4 amps per hour as apposed to 2.6 amps from the standard lithium ion batteries. These batteries will be manufactured to be backwards compatible with all pre-existing notebooks and laptops. HP has also stated that using an optional ultra-capacity battery in its EliteBook will net you a run-time of up to 24 hours without needing a charge!
If people pickup these batteries it will help out the green movement just because people wont be replacing batteries as often.
You will start to see these batteries on the market in the next little while.
