There are many ways to go about buying laptops now-a-days. Pretty much what this means is that many different people buy used laptops. Whenever you go to buy a used laptop, one of the main things that you are going to worry about is the quality of the battery. Testing laptop batteries is one of the best things that you can do before you buy a laptop, and if you are not able to you should test it as soon as you get it. If a laptop has a bad battery that does not mean that you should not get it (because you can just buy a new one). But it’s good to know if you are going to need to get a new one or not.

There are many different ways of testing laptop batteries. If you look around online you will see that many different people test their batteries in many different ways. However, either way you choose to test your battery, you want to have something running. Many people think that they can just turn on the laptop and let it sit there. Then after a hour or so they come back and see if the laptop is still on. This is not testing your laptop battery. You have to have the computer running something, and it helps if it’s using the CD-ROM drive as well. The more things that it has going on it at once will let you see if the computer can hold a charge. After testing the computer you will be able to make a good choice on whether you would like to keep the battery that you have or if you are going to need a new one. Please keep in mind if you buy a new computer you should aways fully charge the battery first before using the computer. Otherwise you could damage the laptop battery.

Mitch Bartlett has written in several times before with tips and tricks. They are always excellent advice. This time, he is giving me a few pointers about extending the life of my battery in my laptop. I wanted to share these with you.

Whenever you get a laptop one of the first things you want to know is how good is the laptop batteries that it has. Well unless you buy a real top-of-the-line laptop, the battery is probably not going to be that great. Of course worry not, because you can buy better laptop batteries online or at stores. I have never had a laptop that had a great battery to start with, but after buying some laptop batteries online I found that this is the way to go. This way you can spend as little or as much as you want on your laptop batteries. Some of the laptop batteries can cost a lot to almost nothing, but remember that you get what you pay for.

Buying laptop batteries is not something that has to be hard, however, it seems like if you buy them online you can get a better deal than you can buying them in stores. I think this is because you can compare prices to other stores online. It is hard to run around town comparing different laptop batteries. Not only are you not going to save very much money, but after all the driving around your savings will be eaten up buy gas prices. Of course, I think that is why I like to buy everything online, and this includes laptop batteries.

A whole desktop computer is equivalent to a laptop and I suppose the reason why laptops are preferred instead of desktop computers is because of their mobility which is only possible through laptop batteries. The portable machine can be moved around from one place to another without going through any hassle. Due to the laptop batteries, the machine is ideal for businessmen and college or university students to make their presentations, projects, business dealings and assignments while having a combine study at a friend’s place or colleague. Thanks to the laptop batteries, light weighted and their miniature size, life is now easier than it used to be.

A notebook computer which is completely correspondent to a desktop computer is always preferred for multiple reasons. First there is the fact of a laptop being portable which is ideal for students and businessmen for their daily assignments or presentations respectively. Now with wireless internet connection you can stay logged on to the internet at all times from everywhere and anywhere. The touchpad on the laptop is used as a mouse and the compact keyboard is great and comfortable for typing. Just for the reason that a laptop is small in size does not mean that the comfort of using a laptop is compromised. The best feature that keeps laptop in the spotlight no matter what kind of modern desktop computers is in the market is laptop batteries that make mobility possible in the first place.

Earlier when laptops were new to the market and was still being experimented to make them even better for use, nickel-cadmium laptop batteries were used. But due to being temperature sensitive and highly expensive the use of them was substituted by lithium-ion batteries. These batteries are also temperature sensitive but can resist a lot more heat than nickel-cadmium batteries in addition they are not that expensive making the prices of laptops affordable. Now if you are planning on purchasing a laptop batteries here are a few things that should be considered. First of all make sure that the battery is new and original as used or counterfeit laptop batteries may be cheap but will be a waste of money due to their short life and flimsiness.

Laptop PCs need longer battery life. I used a flash-disk based laptop for much of the ’90s and loved its 10-hour laptop battery life. You just have so much more freedom when you don’t need to worry about keeping a laptop battery charged.

I’ve been very interested in how flash drives could extend notebook battery life. Using a Kill-a-watt power meter I ran some experiments with an Intel Core Duo notebook. Power use is a little more complex than I’d thought. Here’s what I found.

Laptop config:

• MacBook with the 2 GHz Core Duo,
• 2 GB RAM,
• Intel 950 integrated graphics,
• 13 inch screen,
• 8x DVD Drive,
• 160 GB Western Digital Scorpio 2.5″ 5400 RPM HDD,
• Bluetooth,
• Wi-FI

One of the nicest things about the MacBook is that disk drive removal is easy (see the 1 minute video here). I ran the tests with the internal Scorpio drive removed and ran the MacBook off an externally powered FireWire drive.

Instrumentation
In addition to the Kill-a-watt power meter, which sits between the wall power and the MacBook’s power adapter, I also used the most excellent open source MenuMeters utility. MM shows CPU, memory, disk and network usage, typically sampled over a user-selectable 1-2 second period…

While the portability of laptops is the main reason they’ve grown increasingly popular, that portability comes a price, namely rechargeable batteries. Not only do these batteries limit how long you can use the computer away from a power outlet, they gradually lose their ability to hold a charge.

Battery Health Monitor: Another freeware option, not quite as pretty as CoconutBattery, but gives you most of the same information. Battery Health Monitor has a grid at the top that shows you the power status of the laptop. When plugged in, the word “A/C Power” is bold for example; when on battery power, the word is grayed out.

Other indicators include “Battery Depleted” and “Not Chargeable,” neither of which you’ll want to see bolded. Battery Health Monitor also tells you how many charge cycles the battery has gone through as well as the current voltage the battery is delivering.

SlimBatteryMonitor: This piece of freeware is essentially a fancy replacement for Apple’s laptop battery icon.

While it does not provide any of the supplemental data the other options do, SlimBatteryMonitor’s main attraction is that it takes up less space in the menu bar than Apple’s built-in version and is much more customizable, particularly in the colors you can choose for the battery icon…

Lithium Ion notebook batteries wear down because of two factors:

1. active usage in your notebook battery
2. natural aging of the notebook battery

Both will wear down your notebook battery over time; the trick is to minimize their impact while still getting the performance out of your laptop battery that you need.

The most important thing to understand about laptop batteries is that they are always losing a small bit of their charge. The hotter the temperature, the faster notebook batteries loose their charge. So rule number one is: keep your notebook battery cool. Notebook battery manufacturers store their products at around 60F.

The second most important thing to understand about notebook batteries is that their capacity decreases with each cycle of charging and discharging. By itself, this is not surprising - but when combined with the previous point, it leads to a surprising conclusion.

When laptop users leave their laptop battery inside the machine but leave the computer plugged into the wall, the laptop battery is going through a constant charge-discharge cycle. The notebook battery is sitting unused inside the notebook, discharging a little faster than normal because of the notebook’s heat. Once its charge level drops to a predetermined level, the AC adapter provides extra juice to “top off” the notebook battery. As the laptop battery gets older, it tends to self-discharge a little faster, which accelerates the process even further…

There are three refurbished notebook battery types, each named for its component materials:

Nickel Cadmium batteries (NiCad battery) are hardly ever seen anymore. They have dismally low capacities (2000-3000 mAH) and contain heavy metals that harm the environment. Worst of all is the dreaded “memory effect”. When you recharge a Nickel Cadmium battery before it is completely drained, the longevity of the laptop battery is compromised. That is the memory effect.

Nickel Metal Hybrid batteries (NiMH battery) have twice the capacity of Nickel Metal Hybrid batteries (4000-6000 mAH) and are half as susceptible to the memory effect. But these too are becoming rare.

Lithium Ion batteries (Li-Ion battery) are today’s laptop battery standard. They have all the capacity of a Nickel Metal Hybrid battery, but zero memory effect and zero toxins. Bonus: Li-Ion notebook batteries weigh half as much as Nickel Metal Hybrid laptop batteries. In purchasing a notebook battery, the consumer has three options: used, refurbished, or new.

Used notebook batteries that are not refurbished will probably only last you 30 minutes to an hour before needing recharging…

Laptop users love to complain about how their notebook batteries don’t last long enough. But what if you could get more life out of your laptop battery?

Peter Robbins knows when he turns on his two year old laptop, he doesn’t have long to work.

“My laptop battery dies within a half hour,”

Robbins said.

And when he forgets to watch the power meter,

“all of a sudden it will just go into standby mode and you lose whatever you’re working on. It’s pretty frustrating,”

Robbins said.

Pc Magazine’s Cisco Cheng says no matter if a laptop user has an old, fast dying battery or just can’t plug in, there are simple ways to squeeze out more power when running on a battery. One easy tip: dim your screen.

“Dimming it by 50 percent or even to a level that you can tolerate, can have a profound effect on battery life,”

Cheng said.

Cheng says if you don’t need to be online, disable the wireless connection. Also, pick your programs wisely. Avoid using music and video players, and doing things like watching a DVD, or playing games.

“They can tax your CPU and your battery,”

Cheng said.

“If you’re running a web browser, if you’re running word processing programs, those don’t usually take a toll on your battery.”

Make your battery stronger with regular exercise. Cheng says do something called conditioning everyday…
