Extended HP Pavilion DV6000 Battery Buying Guide

Research Your Battery Buy

Aside from portability, is there any feature more important in a notebook than battery power? For many users, a notebook purchase is dependent on the machine's ability to run for the desired amount of time on battery power. Some people know they won't have access to an outlet while on the go while others would simply rather not deal with the hassle of cords and plugs even while in their own home or office.

Everyone uses a notebook differently. The right battery can make an otherwise lackluster notebook into a great traveling companion and can change the way you use your notebook. We recently used an HP dv4t notebook with the 12-cell extended battery, which made all the difference (you'll see how on the following pages).

If you've been thinking about getting an extended battery for your notebook or have wished many times that your notebook had more juice in it after it went dead, this article will give you a better idea of the options available and what you should take into consideration when choosing an extended battery.

Do You Really Need An Extended Battery?

Your work (or play) may already define how you spend your day, and throwing a notebook into the mix will certainly change your existing routine. If you already have a notebook, think about how you use it and where you use it. Do you keep it on your desk plugged in constantly or grab it with coffee before you bolt out the door every morning? Do you need five to eight hours of battery power every day or do you spend the same amount of time running around town with your notebook and only use it sporadically? Do you carry just the notebook or do you carry a multi-compartment case crammed with accessories?

If you're still shopping for a notebook, you may want to keep those same questions about your future behavior in mind while you're scrutinizing the size, features, and prices of your new laptop. Remember, just because a notebook has the features and price you want, doesn't mean it has the battery life you want. Similarly, just because a notebook is rated at eight hours of battery life in the marketing literature doesn't mean it will have the features and performance you need.

The bottom-line question is: how long do you intend to keep your notebook powered on while you're away from an outlet? If the answer  is "not long," or if you know there will be an outlet close by, buying an extended hp pavilion dv6000 battery will not give you any tangible benefit.

If, however, you know you are going to be nowhere near an AC power outlet and/or need juice in your notebook for several hours to an entire day, you will definitely be better off getting an extended battery or perhaps even two.

Run Time

A battery's run time depends on three main factors: your usage habits, the notebook's components, and the battery itself.

 ZoomLight activities such as Web surfing and office apps will give you much longer run time than multimedia tasks will, such as movie playback and 3D gaming. Indeed, the differences in run times can be staggering when using my own laptop, the HP dv4, with its extended 12-cell battery. I can get five solid hours of online surfing, for example, but that battery time gets cut down to just over four hours for movie watching and only two and a half hours of gaming. If you tend to take breaks frequently while you work, you may find that your battery lasts longer than if you work constantly, since the notebook will run on idle more often. Of course, you should check your Windows power settings and make sure to have "max battery" enabled to get the most from your Dell Inspiron 6400 ac adapter battery.

 ZoomWhen looking at hardware, higher-end components are not always battery friendly. Take Intel's mobile Core 2 Duo CPU. Intel's T-Series processors have a 35 W thermal design power (TDP) rating, but its similar speed P-Series processors run at just 25 W. With 10 W less power, there is more juice left in your battery. In a similar fashion, integrated graphics will consume less power than dedicated graphics processors will because of the relaxed feature set. If your display is an LED backlit screen, it will use less power than the same display that is non-LED. Alternatively, opting for a more expensive, higher-end solid-state drive (SSD) drive that uses 1.5 W will also boost your battery times compared to regular mechanical drives that typically run at 2.5 W.

If you intend to wring every bit of power out of your notebook's battery, you should thus take these hardware issues into consideration when configuring your notebook.

Quoted battery run times are also almost never what you end up getting in real-life conditions. That's because manufacturers will run a common synthetic benchmark, such as MobileMark2007, in order to establish measurable comparisons between different batteries and different notebooks. That's good when trying to compare a Sony notebook to a HP, but the catch is that a manufacturer's testers will often perform these benchmarks on a model that has the minimum hardware that the OEM sells, while using its biggest battery under predefined settings, and quote a simulated maximum battery time. So don't be surprised if that eight-hour rated Dell studio 15 battery only gives you six to seven hours in the real world.

Finally, while it is beyond the scope of this article, the practice of "undervolting" can also yield significant increases in battery times. Undervolting is the technique of lowering the CPU operating voltage at a given clock multiplier in order to consume less power. Results have shown that undervolting offers up to 25% longer performance, which translates into a full hour or more of batter life in some cases. And unlike overclocking, undervolting is nearly foolproof as the worst thing that will happen is that you get the infamous Blue Screen of Death (BSOD). Two great side benefits to this trick are that you will also get an incredibly quieter and cooler running notebook.

home made battery?

What would be the best materials for a time traveler to the early 1800's to build a battery to recharge a portable tape recorder? Electrodes, eletrolyte, and how many cells would be required if the normal recharger puts out 12V @ 100ma? Also please discuss assembly, recommended electrode surface area, distance of separation, etc.

Thank you

If one were to use the right materials (copper and magnesium electrodes), you can squeeze up to ~400mA@1.5V out of a lemon battery.

You would probaby need to put 8 lemons in series at least, but then you would be getting ~400@12V.

Electrode size and seperation should be adjusted to achieve the required voltage/current.
