How to Buy a Laptop Battery?
by toshibasatellite on Dec.11, 2009, under Toshiba satellite laptop

When you have finally decided to purchase s new replacement battery for your laptop you should ensure that the manufacturer has a reliable reputation. If the battery is manufactured by the maker of the laptop then you can rest assured that the battery will be reliable. However, it might come as a surprise to you that most manufacturers of laptops, even the most reputed ones do not manufacture batteries but have an ancillary unit doing so in their name. For instance, if you were to open a genuine Sony battery (not recommended) you will find that he cells inside are manufactured by Toshiba, Exide or some other battery manufacturer. So in the final analysis you are, in fact, buying third party batteries for your laptop. The third party manufacturers of laptops are also buying their cells from the same manufacturers that are supplying the so called OEMs and so is a good bet to buy your replacement battery from. Besides the lower price you will get additional benefits such as an extended warranty and replacement offers. A one year replacement warranty is a must for your replacement battery, so never settle for less.
The other thing to look for when buying a replacement battery is the type of battery. Manufacturers will use many different technologies however, for laptops there are four technologies used. These are Ni-Cad, Ni-MH, Li-Ion, and Li-Poly out of these Ni-Cad or nickel cadmium batteries are a very rare commodity and are being phased out gradually. Don’t go in for a Ni-MH battery if you have a choice between this and a Li-Ion or Li-Poly battery because the Ni-MH battery weighs much more than the rest and have a lower power to weight ratio, meaning it delivers less power than its lighter weight counterparts. Li-Ion and Ni-Poly batteries are the most advanced and last longer. So try for one of these two technologies. Some laptops are designed to use the kind of battery it originally came fitted with, this means if it came with a Ni-Cad battery it must be replaced with a Ni-Cad battery. This is because the internal circuit of the battery must match the laptop hardware for optimum charging and discharging. However, this is not always the case so check with your manufacturer of the laptop if the battery can be interchangeable.
Finally you must study the power ratings of the battery you are buying. Batteries are growing smaller and the power capacity is increasing. Batteries have two ratings marked on them. One will be the voltage and the other Amperes. When buying your replacement battery buy one with the same voltage rating as the old one but try to get a battery with a higher ampere rating. This battery will have longer charge cycles.
Many batteries are rated in watt-hours. This is perhaps the simplest way to rate a battery. The wattage of a battery is calculated by multiplying the voltage by the amperage so a battery with a 14.4 volt rating and an ampere rating of 3600mAh (3.6 Amps) will have a watt rating of 51.84 watts (14.4X3.6 = 51.84).
If the power rating on the battery reads 51.84 watt-hours it means that the battery can supply 1 watt of power continuously for 51.84 hours or 51.84 watts of power for one hour or any combination of the two. No suppose your laptop runs on 17.28 watts (which is pretty unlikely) a 51.84 watt battery will power it for 3 hours. SO divide the power ratings in watts of the battery by the watts of your laptop to see how long the battery will run your laptop.
Sometimes the power ratings in volts and amps on a battery vary. For instance a laptop that runs on a Li-Ion 14.4 Volt, 3600mAh battery may be able to run on a Ni-MH battery with a 9.6 Volt, 4000mAh rating. The Li-Ion battery will be stronger even though the amperage ratings are lower. Here is why:
Li-Ion: 14.4 volts multiplied by 3.6 amps will deliver 51.84 watt hours of power and a Ni-MH battery will deliver 38.4 watt hours of power because 9.6 Volts multiplied by 4 amps will equal 38.4 watt hours. Naturally the Li-Ion battery should be your choice for a replacement battery.

Tips Laptop Battery Life

Laptop battery life is to make sure that your laptop doesn’t overheat. Don’t put use your laptop on a cushion or pillow as this will stop the airflow that keeps your laptop cool. Instead, use a wooden or glass table, which cools part of the air completely. For extra insurance, you can put a book underneath your laptop to make sure that the fan will work and that the air can effectively cool down the area. Putting your HP laptop into hibernate mode may be a slower boot than simply putting it on standby, but this will also save your battery.
Putting your computer on hibernate mode saves your desktop on the last time you use it, but it also shuts down your computer so your battery won’t take up much power. Extending your HP laptop battery life requires that you take good care of your batteries so it won’t get worn off quickly. Make sure that you drain your batteries once a month, and use it at least once a week until it drains.
If you have another laptop battery, keep it charged but store it for only one or two days before using it as the other one charges. Don’t keep your laptop plugged and charging when the Toshiba laptop battery is already full. Doing all these will not only be extending your laptop battery life, but will also make sure that you won’t be spending us much trying to get your computer fixed, or buying new laptop batteries.
Toshiba Laptop battery life is an important consideration if you are likely to be away from a power source for a period of time. Laptops use a rechargeable battery, which can give up to 5 hours of continuous use (models vary) before they need to be recharged. Watching a movie will use up more of your computers battery life than running basic office applications.
Laptop battery life is to lower the brightness of the screen display? its been known that lowering one level of screen brightness will yield up to 10 more minutes of battery life. You can easily do this by going to start > settings > control panel > display and clicking the settings tab. You can also disable those cool effects like cleartype fonts and fade effects to reduce the cpu’s power consumption.
As you may know, many modern HP laptops have a wi-fi built in. Unknown to many people, that wi-fi connection is a power guzzler. Make sure you turn off the wi-fi connection using the external wi-fi on-off switch. If your HP laptop does not offer such a switch, you should go to the control panel > system > hardware > device manager and disable the infrared transceiver, ethernet adapter and bluetooth radio.
