Battery Topic

Not long ago,  HP recall the HP Pavilion，Compaq presario,  HP Compaq and HP series laptop batteries which produced in August, 2007 to January 2008. The reason for the recall is that the laptop batteries may be superheating so that it could melt down the battery or laptop in the extreme case,  if this happens,  it may lead to fire.

It’s not the first time that get to problem about notebook batteries , we still remember the Sony battery problems in 2006. Well, we want to know, why the laptop batteries are so fragile?

As we know, the technology of laptop is very maturity, laptop is very convenience to our life, we nearly can not do some things such as moving business or trip without a laptop.

However the laptop battery, which is not very important to laptop, comes up so many problems frequently.

In this way, some consumers began to worry about the quality of Li-ion battery. According to expert forecasts, although thin-film battery and silver zinc batteries are claimed to replace the lithium battery, but as the replacements are not maturity, we have to use the lithium battery at the present stage.

Now that we can’t evade the problem, let’s face the problem. What we can do is just protect the laptop battery.

Take Acer replacement aspire 1410 battery for example, if you have a Acer laptop, and the battery is acer aspire 1410, you should use AC power more than battery.  Besides, it’s very important to prepare a spare battery. When you are on moving business, you job won’t be delayed.

Today I find a very good article about battery, it talk about green battery, lithium ion battery, NI-MH battery.

From http://www.brighthub.com/multimedia/photography/articles/26177.aspx

With green fast becoming the new black, it’s not hard to see why so many people are opting for Green Batteries for their digital cameras. But what are the benefits to having one for your camera, and more importantly, where can you get them?

Green Batteries

Making the transaction from regular batteries to rechargeable batteries can be daunting. However, in times of economic struggle and worry, this cheaper (and greener) alternative to buying batteries can prove justified. Albeit,rechargeable batteries do not have the best reputation, with users questioning their life spans and usability. Therefore, this guide will explain what the bestrechargeable batteries out there are and where to get them.

There are two main different types of rechargeable batteries available for your digital camera. These are named Li-ion batteries and NiMH batteries and the following will describe both in detail.

Li-ion Batteries

Li-ion Batteries (or Lithium-ion Batteries) are viewed as the ‘best’ of all rechargeable batteries. This is because their density (the amount of energy that is stored within the battery) is higher than most other rechargeables. If you want to get really technical, they also operate at much higher voltages than other batteries. This reduces the amount of cells being used and adds to the over-all effectiveness of Li-ions. They also, depending on how you choose to store them, maintain most of, if not all, of their original power after a charge. Most rechargeables, such as NiCds, lose between 1-5% of their charge a day!

However, there is unfortunately a downside to these batteries. They are known for being the most expensive types of batteries around (due to the complexity of their manufacturing). They also do not become in ‘conventional’ battery sizes, such as AA. This is because of the dangers involved by placing a Li-ion battery into the wrong charger. Li-ion batteries require their own unique chargers (another downside) and different chargers need to be purchased for different types of batteries to prevent ignition.

Li-ion rechargeable batteries can be purchased here.

Ni-MH Batteries

Nickel-metal Hydride batteries are a great replacement for your non-rechargeable batteries. Alkaline batteries can be costly and can run out fast when being used on your digital cameras. This means that if you find running your digital camera to be a little on the expensive side,NiMH batteries may be a worthy investment. They are cheaper than their Li-ion counterparts, however due to their sophisticated design, the NiMH chargers actually cost the same as Li-ion chargers do. Discharge time (how fast a battery loses power when it is not being used) is fairy fast for a NiMH battery. On average, 40% of their battery life will be lost when left sitting for a month. However, if stored in a cooler place (perhaps your fridge) then this will be reduced. Li-ion Batteries will still have a longer ‘shelf life’, but this is to be expected with the differences in price.

There are also several downsides to NiMH batteries. They work at a lower voltage than both Li-ion and most alkaline batteries, meaning they produce very little power in comparison; alkaline batteries normally start their lives with a maximum power of 1.5 volts, whereas NiMH batteries average 1.2 volts. They also may suffer from a memory effect. In short, this is a fear of batteries losing potential power, however an occasional complete discharge should prevent this from happening.

Conclusion

If you are willing to spend a little extra on your batteries then Li-ion batteries are a recommended investment due to their long lifespan. However, if you are looking for a AA, C or D type battery thenNiMH batteries are the way forward. They also cost a lot less and are perfect for a soft-core battery user. Therefore, technology aside, your choice comes down to personal needs. Pick wisely!

More and more people have digital products, the lithium ion battery is a necessary accessory for digital products, so what do you know about lithium ion battery?

Take Sony np-f970 battery for example:

About the battery capacity calculation way:

For example, if your camera digital uses a Ni-MH battery that is 9.6 Volts, 4000mAh and the new Li-ion Digital Camera is 14.4 V, 3600mAh, then you will get more run time the Li-ion.

Example

Li-Ion 14.4 Volts x 3.6 Amperes = 51.84 Watt Hours
Ni-MH: 9.6 Volts x 4 Amperes = 38.4 Watt Hours
The Li-ion is stronger and has more run time.

So as the example below, it’s easy to calculation the WH of  Sony np-f970 battery.

Sony np-f970 battery:

Chemistry: lithium ion

Capacity: 6600mAh

Voltage: 7.4V compatible with 7.2V

it’s 6.6*7.4

So replacement Sony np-f970 battery made by sales-battery.com has high capacity to work on Sony camcorder.

Replacement Canon nb-2lh battery, brand new, with the capacity of 750mAh,  7.4V compatible with 7.2V, nb-2lh battery is guaranteed to meet or even exceed the original battery. Canon nb-2lh battery is lithium ion battery, well, let’s know something about lithium ion battery.

Lithium-ion batteries are substantially better than either of their precursors, nickel cadmium (NiCad) and nickel metal hydride (NiMAH) batteries, in that they do not suffer from the “memory effect”. This means that, contrary to popular belief, you do not need to let your battery run down all the way.

In fact, it’s better that you don’t. Having said that though, I need to add that lithium-ion Canon nb-2lh battery users should allow their batteries to fully discharge on the first two or three charging cycles.

Take care of lithium ion Canon nb-2lh battery, and assort a high quality Canon nb-2lh charger, these two power suppliers will give more power to Canon digital camera, no wonderful sight will be missed.

HP pavilion dv7 series laptops, this stylish desktop replacement offers powerful graphics, great sound, and superb wireless performance. The price of hp pavilion dv7 series are not cheap, so what’s the performance of HP dv7 series laptops?

With its high-res 17-inch screen, built-in TV tuner, and Blu-ray drive, the HP Pavilion dv7 ($1,900 as tested) is particularly well suited for rigorous multimedia use. It offers a sleek design and strong performance, bringing a high-end computing experience to people who are willing to spend more to get the best.

Futuristic New Design

The dv7 is one of three new dv-series notebooks to usher in a fresh Pavilion design. Instead of the old Imprint pattern, the onyx lid now has a subtle grid pattern that extends to the keyboard deck. HP’s logo glows brightly in the upper left corner. Inside, the shiny silver deck, keyboard, and chrome speaker strip look and feel futuristic. As we noted with the 15-inch dv5t, the one downside to this new look is that the surface picks up fingerprints easily. At 8.4 pounds, the entire package is about as heavy as we would expect for a 17-incher.

Above the keyboard is the speaker strip, with a smooth touch-sensitive panel above that. The power button and QuickPlay launch key are discrete controls that are visible at all times. Other controls—mute, volume, rewind, play/pause, fast-foward, stop, and Wi-Fi—glow white only when the computer is turned on.

Occasionally, we found the keyboard slippery, but the keys were comfortable for typing and have a bouncy feel. Although we like the quiet touch buttons and the wide orientation of the trackpad, the cursor on our preproduction unit occasionally jumped to parts of documents we weren’t working on.
Display and Sound

The 17-inch display has a native resolution of 1680 x 1050. Although we generally observed good viewing angles from the top and sides, the screen is reflective when the background is dark. We noticed excellent color and sharpness when watching the Rocky Balboa Blu-ray disc (even in the climactic fight scene), but even in High Performance mode, we wished the screen were a bit brighter. The chrome speakers, backed by a subwoofer, produced thunderous sound.

For people interested in watching TV, the dv7 also comes with a built-in TV tuner, an amenity the 18-inch Acer Aspire 8920G doesn’t have yet. The included remote is lightweight, with buttons large enough to press easily, and it stows away neatly on the side of the notebook. When we watched television next to a window, the sound was excellent, but the resolution was pretty mediocre; then again, this was using the included detachable antenna, which is pretty mediocre itself. The tuner receives both analog and digital signals.

As a replcement battery, HP pavilion dv7 series battery pack is rated 4800mAh, 14.8V, it’s 8-cell high quality battery for hp dv7, lithium ion is a commonal material for batteries now.

Part review from http://www.laptopmag.com/review/laptops/hp-pavilion-dv7.aspx

Never thought that only one battery is enough for laptop, when you are on trip, on the business, on a open field, there is no external power for laptop, and one laptop battery can only last about 2 to 3 hours, the most is 4 hours, so prepare a spare battery is wise decision for laptops.

HP mini 2140 battery pack is brand new compatible battery for HP mini 2140 laptops, the battery of 6-cell, provide electric quantity for laptop, full charged both of your batteries before going out for trip.

4400mAh capacity HP mini 2140 battery feature with lithium ion no memory, don’t discharge fully. It’s a good advice for you.  Rechargeable, so benefit for environment, reduce the pollution, this is HP mini 2140 battery.

Recently, SONY, APPLE, DELL, HP, these international famous PC manufacturers, their  notebook batteries appeared problems and recalled factory. Today, I would like to talk about the  topic of extended batteries, to share with everyone.

Why the laptop battery electronic become less and less? Why using battery correction function will let electricity restore partly? What’s the correctly way to charge lithium ion battery? All of this need to be trace from the battery power calculation.

No matter the NI-MH batteries which have been eliminated, nor the lithium ion battery now we are using, for example the dell vostro 1500 replacement li-ion battery, or unusual lithium polymer battery, even future battery star of the silver zinc battery, all of these are equivalent to a storage battery power of warehouse, the difference is that the way of electronic in and out, the volume. In the notebook computer batteries, there is responsible for the management of these batteries electricity housekeeper – it is manager of managing battery, calculated chips, the calculation for the “owner” charge.

In the battery measurement technique, there are four common methods, but not different brand laptop battery use one of the way to calculate electrical, usually several methods are mixed use, one method is the main for calculating, others are auxiliary power calculation.

The first method is open-circuit voltage measurement, this method is by measuring the battery voltage values in the stationary state to calculate the residual capacity, however as the relationship between the lithium ion battery voltage in stationary and the residual capacity belong to nonlinearity, so the method measured values is not accurate, most of cell phone batteries use this calculation method.

The second method is Coulomb Counting, this method is by measuring the battery electric current of charging and discharging, integral the product of the electric current value and time value, then  the result is the electric of charging into power and the power that is released, Coulomb Counting is a comparatively accurate calculation method of electricity.

The third is impedance measurement method, it is through the measurement of the battery cell resistance values obtained the residual capacity.

The fourth is the comprehensive method, by setting up a related table, enter the parameters such as voltage, current, temperature, then get input residual capacity of the battery query.

Therefore, except battery cell, the internal structure of battery include the management of chips, chips contain one or two battery cell power measurement method, and a charge protection circuit. Notebook computer is in the chip system, through the driver interface access chip, then to establish and administer the battery.

However, why will the battery power is less and less, and execute battery correction function can recovery of capacity? Laptop batteries commonly called 6 battery cells, 4 battery cells, it’s the battery within a few battery cells. So many battery cells make up together, it’s the fundamental reason of less power: the different battery cell’s quality, discharge level is impossible completely consistent, such as when discharging, certain battery cell’s electric quality greatly reduced, in order to maintain the voltage stability, battery management according to the principle of “cask theory”,  according to the the worst day for charging protection, so battery power will naturally dropped, or even more than the battery irreversible chemical physics.
