Get your batteries here!
It's always fun to mark a milestone at a company I'm involved with. Today, Boston-Power and HP are formally shipping the Enviro battery pack which works in 70% of HP's notebooks. You can check out Enviro at the HP online store. Aftermarket batteries (purchased after you already bought your laptop) are expensive. The Enviro battery is only $20 more than the standard battery for these same models. But, the Enviro battery has a 3-year warranty vs. a 1-year warranty on the standard battery. Judging by the comments the standard battery has received on the HP site, it seems like the $20 premium is a very modest extra cost for the 2 extra years of warranty.
The Boston-Power battery addresses the cycle life problem with Li-ion batteries. The battery does not lose capacity over time and through charge cycles. It also has a fast charge feature which allows it to get to 80% charge in 30 minutes. And, since it is not made with hazardous chemicals and has a very long cycle life (you won't have to throw it away when it loses capacity), it has received the Norid Ecolabel for environmental friendliness.
If you own one of these HP laptops, you should consider the Enviro for your next battery:
HP Pavilion dv4, dv5, dv6; HP HDX 16; HP G50, G60, G61, G70, G71; Compaq Presario CQ40, CQ45, CQ50, CQ60, CQ61, CQ70, CQ71
And, if all goes well, you'll soon be able to order an Enviro battery with a new laptop purchase or buy one at a local HP retailer.
Congratulations to Boston-Power for becoming the first US vendor to get a battery certified by a major laptop manufacturer!
