Today i search HP Pavilion DV2000 Battery on google, i open the the first position then

i read the Guests Messages, find all the messages said the battery has some Quality

problems.

One problem the Shape is not suitable:

Disappointing at best. Takes forever to charge up, loses power quickly when inactive,

and not much more life than the standard battery that came with hp pavilion dv 2000

laptop. I should have looked up the word extended in the dictionary before purchasing.

The second problem not full charger:

Well, I got the battery, and it was nice at first. It was about 75% charged and so I

tried using my laptop with the battery without the adapter. It lasted a few hours, which

was much better than the 12 cell battery(8800mAh) I got with my HP dv2000 laptop that

didn't last even 2 hours.

The problem is, when I tried to recharge the battery, it doesn't work! It charges up for

a little bit (to 15%) and then stops for no reason. I'm using XP, and the battery icon

in the task tray says "plugged in, not charging." I don't know if XP has anything to do

with this, but my previous battery certainly did not have this kind of problem.

I tried taking the battery out of my laptop to let it rest, and then put it back to

charge it again, hoping my laptop will finally get used to it and charge it all up to

100%, but it stopped at 20%, 40%, 50%, 80%, 90%.

Why should they continue to sell HP Pavilion DV2000 Battery? As far as I am feeling the

12 cell 8800mAh HP Pavilion DV2000 battery should have the quality as below:
This is one of the best purchases I have EVER made. I pretty much wouldn't be able to

function without my laptop between school and work so having this battery has been a

miracle. It lasts me about 5.5 hours and also doubles as a lift on the back of my

computer. This is helpful when the little fans are going so the heat escapes easier.

Quick Test the battery(Pavilion DV6000) has a secret lies,To a large extent,you should understand how the battery is being loaded.Different short-circuit the battery load current pulse. EV088AA laptop has long and fluctuating loads, and has the power tool about intermittent heavy.

Because of these differences in loads, a battery for a digital mobile phone should be tested primarily for low impedance to assure a clean delivery of the current bursts, whereas a battery for a notebook should be examined mainly for the bulk in energy reserve. Ultra-low impedance is of less importance here. A battery for a power tool, on the other hand, needs both — low impedance and good power reserve.Some quick testers simulate the equipment load and observe the voltage signature of the (417066-001) battery under these conditions. The readings are compared with the reference settings, which are stored in the tester. The resulting discrepancies are calculated against the anticipated or ideal settings and displayed as the SoH readings.

The first step in obtaining quick test readings is measuring the battery’s internal resistance, often referred to as impedance. Internal resistance measurements take only a few seconds to complete and provide a reasonably accurate indication of the battery’s condition, especially if a reference reading from a good battery HP Pavilion DV2000 is available for comparison.Unfortunately, the impedance measurement alone provides only a rough sketch of the battery’s performance. The readings are affected by various battery conditions, which cannot always be controlled. For example, a fully charged Presario V6000 battery that has just been removed from the charger shows a higher impedance reading than one that has rested for a few?hours after charge. The elevated impedance is due to the increased interfacial resistance present after charging. Allowing the battery to rest for an?hour or two will normalize the battery. Temperature also affects the readings. In addition, the chemistry, the number of cells connected in series and the rating of a battery influence the results. Many batteries(Presario V6000) also contain a protection circuit that further distorts the readings.
