please recycle the batteries

We use more and more electronics, it one problem to recycle increasing batteries.

When the batteries are no longer good on your remote control, child’s toy, flashlight, power tool, or car you shouldn’t just put it in the trash and forget about it. Batteries take years to decompose and release dangerous chemicals into the soil, water, and air.

The disposal of batteries is such a large issue places around the world are starting to require the recycling of batteries. For example in some European countries they have made it a law to recycle them. In the United States many states have regulations in place requiring battery recycling. The US Congress even passed the Mercury-Containing and Rechargeable Battery Act in 1996 to make it easier for rechargeable battery and product manufacturers to collect and recycle Ni-CD batteries and certain small sealed lead-acid batteries. For these regulated batteries, the act requires:

• Batteries must be easily removable from consumer products, to make it easier to recover them for recycling.
• Battery labels must include the battery chemistry, the “three chasing arrows” symbol, and a phrase indicating that the user must recycle or dispose of the battery properly.
• National uniformity in collection, storage, and transport of certain batteries.
• Phase out the use of certain mercury-containing batteries.

Some cities and states have taken it upon themselves to ask individuals to properly dispose of their batteries. For example, California passed a series of laws called the California Universal Waste Rules, that requires these batteries to be recycled.  Seattle, WA is having it’s first Area-wide Battery Recycling Day on Thursday, June 28, 2012. By going to you can find a battery recycling center near you and answer the call to improve our environment just as these places have.

DELL VOSTRO 5460 Test

Today I recommend a article introduce Dell vostro 5460 laptop from blog.omy.sg.
At just 1.54kg, this 14-inch lappy is touted as Dell’s sleekest of its ultra-portable series.  And thanks to SAFRA, I had a chance to review one of those babies!

At only 18.3mm thick, the Vostro is housed in a brushed-aluminium chassis. The laptop is available in 2 colours; Fire Red and Graphite Silver. The computer comes with a Dell Software Backup, Recovery Manager and System Restores to enhance the security of our personal data.

The sleek machine also comes with a dual fan cooling system to minimize heat emission. However, if you’re into pin-dropped silence the fan might sound a bit too loud for your liking after a while. The full-sized keyboard deserves a mention for being well built and also for its comfort and ease.

The battery is supposed to last for approximately 4 to 5 hours. But I realise that the actual life span of each full charge can only last for about 3 hours for casual use. However, If you are a hardcore gamer, you might want to keep the charger by your side.

There’s plenty of storage space with the 500GB HDD for all your documents and multimedia files. And if you are going to opt for the 32GB SSD memory card upgrade, it can definitely boost up the performance level of the laptop.

The Intel® Core™ i5 with Nvidia GeForce GT630M 2GB DDR3’s graphical capabilities enhances the overall gaming experience. But it’s a pity that the Vostro 5460 doesn’t come with a touch screen though it was installed with Windows 8. That could possibly be attributed to the affordability of the product I suppose.

Another downside to the laptop is it’s not so reliable Wifi connectivity. I faced a hard time trying to stay connected via both my fibre broadband and my iphone wifi.  With a decent spec and price, this laptop doesn’t really burn a hole in your pocket.

My conclusion: Light on weight and pocket for daily computing and leisure needs.

The Dell Vostro 5460 is available at following starting prices (incl. GST):
•Vostro 5460 with Windows 8 starts at S$799
•Vostro 5460 Ultrabook with Windows 8 starts at S$1,099

Maintain Your Dell Vostro 1500 Battery

So many guys bought Dell Vostro 1500, but does everyone know how to take care of the laptop battery?

Dell Vostro 1500 Battery is one of the best models in the market that have long lifespan, battery life and guarantees users great value for money. This battery’s effectiveness is however mainly pegged on how you take care of it. Here are important tips you should use to take care of the batter and realize higher value for money.

Take caution from the time you go selecting it

You can only enjoy greater service from your battery for Dell Vostro 1500 if you select the right quality. If you get the wrong battery, cells could be compromised and make it impossible to store adequate charge for your laptop. Take time to identify a battery for Dell Vostro 1500 in its top condition by purchasing the model that has long guarantee from authorized dealers. Also make sure to confirm the seller’s commitment to quality by reviewing the mission in the seller’s website.

Avoid total discharge of Dell Vostro 1500 Battery

Dell Vostro 1500 Battery effectiveness is dependent on the quality of cells and Li-Ions. Complete discharge of the battery easily destroys the cells and ions which compromises the battery life. This problem can be worsened and accelerate breakdown of your battery when it occurs frequently. It is advisable that you always plug the laptop to the mains when the power meter reaches 10%.

Avoid overheating the battery

Heat is perhaps the greatest danger that can destroy your Dell Vostro 1500 adapter or battery. Overheating will destroy the cells and accelerate the tearing process. You should therefore avoid placing the laptop or the battery on hot objects such as microwaves, boilers or even ovens. You should also avoid using the laptop without cover if you are working outdoors on a hot day. Overheating can also result from running heavy programs concurrently. For example, the laptop will start overheating if you are gamming, downloading large files and playing music at the same time. If you note the laptop temperatures going beyond the range of 50-60 degrees Celsius, close down some applications.

Plug the laptop and work direct from the mains

If your power supply is stable, you can disconnect the Dell Battery and work from the mains. The process of charging and discharging contribute to progressive wear and tearing of the battery. Even though the battery is designed to allow power bypass to the laptop after it is fully charged, it can only be possible in an ideal situation. Wear and tear of the battery and laptop makes the power to release some heat that can destroy the battery and the laptop. If you follow these caring tips, you are assured of getting more from your battery.

Reduce power consumption and increase battery life

The computer consumes a lot power, but we can use some simple energy-saving methods to save energy costs as well as protect the environment. If you are using a laptop, these methods can also effectively improve battery endurance.

Conventional measures

1. Pending the computer when not in use. This can significantly reduce the use of electricity and the computer can be quickly waked.

2. Turn off the computer if you do not use it long term. Some people worry that regularly shut down the computer may result in faster loss, this understanding is not correct.

3. Turn off the external devices (printers, scanners, etc.) when you not use.

4. Reduce the brightness of the screen; laptop screen account for the main consumption of laptop. Most laptop keyboards have a button that can adjust the brightness.

5. If you do not need internet connection for short time, turn off the wireless / Bluetooth devices. These devices consume a lot of electricity. Some computers have equipped with a physical switch of wireless adapter and Bluetooth devices, and some computers have a keyboard shortcut alternative physical switch. You can select it depend on your needs.

More advanced measures

Reduce the tasks that running in the background, the more tasks that performed, the more power the computer needs. Most program that consume less power when in the minimize state, but the applications, music and movie player, distributed computing software that often need to fetch data from the network may affect the power consumption.

Laptops with the Longest Battery Life

What good is a notebook that dies two hours after it’s unplugged from the wall? Not much. We’ve created a list of the clamshells that ran the distance on the LAPTOP Battery Test (continuous web surfing over Wi-Fi).  Each machine lasts (at least) to the 8-hour marker, but some systems use larger, sold-separately batteries to stay active up to 20 hours. See for your yourself below.

Consider the Lenovo ThinkPad X230 the poster-laptop for systems with optional batteries. The 12-inch ultraportable ships with a 6-cell battery that lasts a decent 7 hours, but the sold-separately 9-cell option pushes the juice supply beyond the 12-hour mark. If that's not enough productivity time for you, the X230 also works with a sheet-battery that, when paired with the 9-cell, helped the system run an epic 20 hours!

and my friend said: I've been using the T430 for months now with the 9-cell battery, AND the additional 9-cell slice battery, and the battery life is almost unbelievable. I can easily work through the day without charging and I've yet to run out of battery on it. But it's a heavy beast with 18 cells ;).

Laptop battery optimization

Battery is an important component when maintain a laptop. When activate a laptop, many people prefer to run out of the power until the laptop automatically shutdown, and then charge it with an external AC adapter for 12-15 hours, after fully charged then discharge, repeat such process for three times to completely activate the battery. But, this is wrong!

This kind of method is for the nickel-cadmium, nickel-metal hydride rechargeable batteries, but not applies to nowadays lithium batteries and lithium polymer batteries, over charge and over discharge will cause irreparable harm to lithium batteries so we should take it carefully. Besides, keep the battery in the laptop when using an AC adapter to charge won’t cause over charge, because there is charging control and protective circuit in laptop which can stop charging when battery is fully charged.

It is recommended to charge and use anytime with lithium battery, do not over charge and over discharge is the best way to protect your battery. As for battery depletion, lithium and nickel-metal hydride battery is different at different stages that will have different behavior, how to reduce the loss? Remember, never over charge and over discharge.

The tips of maintain digital camera body

Digital camera body maintenance:

The general appearance of a digital camera is industrial plastic alloy material, usually through special processing to do some texture process on the surface to look more beautiful. But in our actual use, there will inevitably left some fingerprints, traces of oil, dust and other dirt on the surface of the camera, order to avoid further damage caused by the dirt, we need to do some basic protection and regularly clean for our camera body.

Screen protective film

This does not seem to have much to say, businesses will generally give you and paste for you, you can help your camera screen avoid of some small bump. You’d best buy some more and cheap screen protector as a backup, when the protective film was scratched you can quickly replace another one but instead of trying to find.

Screen guard

This should be an enhanced one of screen protector, Nikon SLR will supply. Though it is ugly, the protection of the screen is indeed a lot stronger.

Soft brush

It is used as a simple soft brush to clean the dust, mainly to choose one that less drop hair, and you should use it lightly.

Blowing

Blowing used in the body can also clean the dust, by using the strong gas jet to blown away more stubborn dust.

Cleaning fluid

Cleaning fluid is used in a particular case, to deal with stubborn stains and body contacts clean. Generally use a cotton swab dipped a very small amount of cleaning fluid to do the subtle position cleaning for body.

Some digital camera accessory is helpful to your camera.

Time annual best laptops: Apple ranked the first three

In October, Time magazine has awarded the best laptop batteries in 2013, the result showed that three of Apple products have occupied the first three positions, they were 15.4-inch Retina MacBook Pro, 13-inch Retina MacBook Pro and 13.3-inch MacBook Air. Both Retina MacBook Pro are last year's products, and MacBook Air is just updated for Haswell processor this year.

The editor of Time magazine Ben Taylor said that, maybe you are a geek, maybe you want to purchase a most cost-effective laptop, maybe you want to know which laptop gets the highest scores that with thin and light body, outstand performance and good reputation, then I would tell you that the two Retina MacBook Pro and new released MacBook Air are your best choices.

It‘s known that this selection by Time is a result of research and statistic of over 1000 laptops in the market, so the persuasive is self-evident. There is earlier news shows that Apple will hold a new production conference in the middle of this month, in addition to the new generation of iPad, the Retina MacBook Pro with Hashwell processor will also show up in the conference.

Buy an excellent laptop battery wisely online

I searched the ‘laptop battery’ in Google before I wrote this article and it returned about 52 million results. It made me excited but also depressed me at the same time, because I had a plenty of options to buy what I need, but too many options made me somewhat disoriented. After a series of setbacks, I finally got what I want, and now, I feel glad to share my experience of buying a laptop battery.

1. Write down the exact model of the battery. Battery model is a unique identifier assigned by manufacturers to each laptop battery. Be sure to use the battery model when you are searching a battery. For example, I want to buy the Dell Inspiron 15R battery, which shows that the manufacturer is DELL and the battery model is Inspiron 15R.

2. Check the battery capacity. Battery capacity means the battery operating time. At the time of purchase, we must check the battery capacity, which determines how long your computer can be used.

3. Check the voltage. The most common laptop battery voltage values are: 7.2V, 9.6V, 10.8V, 11.1V, 14.4V. Laptop’s voltage is fixed, and the battery voltage may have a slight deviation, such as 11.1V and 10.8V. But you can not use a 7.2V battery if your laptop needs a 14.4V one actually. The original voltage of my laptop is 10.8V, so I can also use the 11.1V battery either.

4. Do not always pursue a low price, you should focus on the after-sale service and warranty. Having taken all the basic factors into account, we can finally make a payment. We should consider the reputation and peoples’ recommendation at first when we choose a dealer, and then check the price, after-sale protection and other relevant policies. Do not buy product which is not guaranteed but only cheap. In order to facilitate everyone, I recommend a few good websites for reference.

Does rechargeable battery have a best status

Google
There is a saying that, if rechargeable batteries used properly, they will reach a best status within a certain range cycle which is to its largest capacity. This situation depends, sealed nickel-metal hydride batteries and nickel-cadmium batteries, if used properly (e.g. regular maintenance to prevent the generation and accumulation of memory effect), usually after 100 to 200 cycles can reach its maximum capacity, for example, a NiMH battery leave the factory has a capacity of 1000mAh after 120 cycles, and its capacity may reach 1100mAh. Nearly all Japanese nickel-metal hydride battery manufacturers’ technical specifications book describes the cycle characteristics of nickel-based batteries.

★ Nickel-based batteries have the best condition, generally between 100 and 200 cycles to reach its maximum capacity

For liquid lithium-ion batteries, but there is no such a cycle capacity peak phenomenon, from the lithium-ion battery leave the factory until the final battery scrap, its capacity reduced every time you use it. When I was right to do cycling performance test of lithium-ion batteries, I have never seen the signs of capacity recovery.

★ lithium-ion batteries have no best status.

It is worth mentioning that, the lithium-ion battery is more susceptible to environmental temperature changes and the performance of different properties, in 25 to 40 degrees environment it will exhibit its best performance, and low or high temperature state, his performance is greatly reduced. To get your lithium-ion battery fully demonstrated its capacity, we must be careful attention to the environment, to prevent the high temperature phenomena, such as mobile phone on the car's front desk, direct sun at noon is very easy to make it more than 60 degrees.

What is the memory effect

Battery memory effect refers to the battery reversible failure, that battery failure recovery performance. Memory effect refers to the battery for a long time in particular work cycle, automatically keep this particular work trend. This was first defined in the nickel-cadmium batteries, the bag nickel-cadmium battery does not exist memory effect, while sintering batteries have. And now the nickel-metal hydride battery is not restrained by the definition of memory effect.

Because modern nickel-cadmium battery technology improvements, the memory effect has been greatly reduced, while the other phenomenon replaces the definition, that is, nickel-based batteries "lattice", usually, nickel cadmium batteries by both effects of the combined effect of the nickel-metal hydride battery only by the "lattice" of memory effect, but also affect the relatively small nickel-cadmium batteries.

In practice, the elimination of the memory effect has the strict specifications and an operation process. Improper operation will be counterproductive.

For nickel-cadmium batteries, regular maintenance is periodic deep discharge: the average use per month (or 30 cycles) to a depth of discharge (discharge to 1.0V / each section, or call it exercise), normal use is to try to run out of battery or use other means to shut down the formation of memory effect can be mitigated, but this is not exercise, because the instrument (such as mobile phones) is not used 1.0V / per session before the shutdown, it must be specialized equipment or lines to complete the work Fortunately, many of NiMH battery charger comes with this feature.

For long-term no exercise nickel-cadmium batteries, because of the cumulative memory effect, cannot exercise to restore capacity, when you need a deeper discharge, which is a very small current to the battery for a long time discharge to 0.4V each section a process that requires specialized equipment.

For NiMH batteries, exercise frequency conducted once every three months to mitigate memory effect effectively. Because NiMH battery cycle life is far below the nickel-cadmium battery, almost no recondition this method.

▲ Recommendation 1: It is not necessary to discharge the battery before charge, and also harmful, because the battery life is shorten.

▲ Recommendation 2: Use a resistor connected to the positive and negative of battery to discharge is not desirable, the current cannot be controlled, easy to reach 0V, and even lead to series battery polarity reversal.

What if laptop battery has a problem

Most models have a battery protection circuit, when the battery temperature is too high or when the discharge current is too large, probably because it beyond the battery protection circuit standard that occur the problem of power failure automatically.

The most common situation is that the use of laptop battery when running at full speed causing excessive current automatic protection. For example, remove the content from the DVD in CD-ROM into the hard disk, then the host and peripherals are consuming a lot of power, it is possible that the current exceed the battery standard of protection, in which case do not panic, as long as disconnect peripherals to wait for about 10 minutes and then re-boot.

Another common situation is the laptop in a hot environment, high-load operation using the battery, so that the ambient temperature plus the heat generated by the battery self-discharge battery protection circuit may exceed the preset temperature, this situation may occur especially in high frequency P4 machine after high speed operation at high temperatures. Encountered such a situation you should remove the battery and place it in a cooler place (remember not placed in the refrigerator to frozen!), after half an hour it would be back to normal. For high temperature can damage lithium battery a lot, less than not you should avoid use the laptop in a hot environment and work high load.

In order to maintain the BIOS state, there are many laptop battery with calibration option, in simple terms, this functionality would charge laptop battery fully and then discharged completely , then recharge, so not completely discharged for long-term, cumulative errors caused some corrective action. However, please note that the BIOS correction takes a long time, you’d best do that before go to bed.

Many models also have discharge functions in Windows. This can save time, you can do that while working. Battery calibration should not be too frequent, frequent deep discharge will shorten battery life, we recommend two to three months once.

If all the ways do not work, you need a new laptop battery.

Is an accessory can support laptop for 14 hours really worth buying?

Laptop battery endurance is an important performance indicator; it is also what I have been considering. Recently, a supplier of accessories called Powertraveller introduced a powerful battery accessory, allegedly for notebook provides 14 hours of additional usage time.

This product called Silverback-Gorilla, which has been built in a staggering 60,000mA battery, through 240V AC outlet output, users can also adjust to the minimum 80 volts (50-60Hz) according to your need. This will provide laptop 14 hours of extra work time. When I see these data, I admit that I was excited.

However, I gave up buying this product, even though it is of good performance. 2.5kg of weight, price up to 450 dollars, any one is my reason to abandon it. Finally, I chose to buy a spare battery online.

Since I have decided, the things left are quite easy. In Google's search results, I select the www.all-batteries.co.uk for the simple reason, one year of service, 30 days refund and reasonable prices. I have made my choice, how about you?
