I just got a HP DV4000. Unfortunately, the battery that came with it sticks out about 3/4" so that the laptop does not really lay flat ( I'm "guessing" this is not the 6 cell battery, but the extended 12 cell. How / where can I get the regular battery?? - manzoor
here is an 6 cell hp dv4000 battery ,fellowing this address http://www.notebook-batteries.org/ [...] series.htm , may be help you!!
eBay has a crap load of batteries. I know a lot of stores with laptop technicians carry spare batteries, too. I personally have 2 DV4000 batteries lying around, but unfortunately they're not for sale unless you come up to me in person.
i found an online store is wonderful, maybe you can find what you want here http://www.goodlaptopbattery.co.uk Ture or not,you make a judge,please!
