The Capacity of Laptop Batteries Explained
Laptop batteries are rated by, Voltage (V) and Milliamp-hours (mAh).
Voltage
is the rate at which energy is drawn from the battery and Milliamp-hours Represents the capacity of the battery. The Milliamp-hour rating Corresponds to the run time of the battery.
A battery with a high Milliamp-hour rating has a relatively longer run time than a battery with a Low Milliamp-hour rating.
Batteries with different Milliamp-hours can be used on the same laptop provided the voltage rating is the same. The voltage rating has to match that of the original battery or as recommended by the computer manual. Using a battery with a different voltage setting can seriously damage the laptop.
The power ratings of most compatible/replacment batteries are higher than the original manufacturers’ batteries. This will not damage your laptop, in fact, it simply means that these batteries in many cases last longer than original manufacturers’ batteries.

The run time of a laptop battery will vary on individual notebook computers, based on the applications being used (i.e. high graphics, games),
the number of times something is saved or retrieved from the hard drive and/or CD Rom drive, the memory of notebook, and chemistry and capacity of the battery.
A ‘realistic’ average run-time for a battery is 1.5 to 3 hours. Using devices like a wireless adapter on the laptop also drains the battery considerably.
The life of a battery under normal use is around 500 to 900 charge-discharge cycles. This is about one and a half to three years of battery life for the average user. As the rechargeable battery begins to fail, the running time of the battery begins to decline.
Laptop Batteries are More Than a Black Box
More than meets the eye.
Laptop batteries are the most important battery in the field of rechargeable batteries, but they are also the most complicated and regulated of all rechargeable batteries.
The process alone to manufacture a laptop battery is long. How laptop batteries interact with the computer to function properly is another lengthy process. Manufacturers are also working constantly to improve laptop battery technology.
The process used to created laptop batteries involves a system of tests and re-tests to insure safety and reliability.
Inside that plastic case that is the finished product, there are a number of components besides the battery that make it work.
Inside the casing, there are safety fuses, breakers, thermistors, and charge electronics which all aid in the functionality of laptop batteries.
The battery pack casing is welded together in a specific process and is then sent on for final inspection. During final inspection, tests are documented for form, fit and function and once the battery passes the test, it is labeled with a lot and date code.
All those extra components added to the battery pack are essential for laptop battery functionality.
The thermistor controls the resistance of the battery and tells the computer to stop charging when the battery heats up as it completes charging. The circuit breaker helps protect against over charging and short circuits.
Laptop batteries are built with the best quality battery components that can be found. Battery cells are ensured to yield the highest capacity and safety qualifications, whether the battery cell is NiCD, NiHM, or Li-Ion.
Some batteries are even equipped with their own microprocessor that communicates important charge information to the computer.
Information about laptop batteries proves that they are some of the most advanced rechargeable batteries available.
Now when choosing a laptop battery, you won’t just see a black box, but rather a mini-computer that helps your laptop to run reliably and effectively.
Which Laptop battery is right for you?
The short answer is: “Whichever type fits your laptop.”
Laptop batteries vary according to the model and type of laptop computer for which they’ve been designed.
All laptop batteries do, however, share some common characteristics that differentiate them from regular household batteries:-
• Laptop batteries are rechargeable
• They are composed of multiple internal cells
• Within each laptop battery is a small printed circuit board
• Shape and location of terminals differ from model to model.
As is the case with all batteries, laptop batteries create an electrochemical reaction, forcing a stream of electrons from one position to another. Also like other batteries, laptop batteries have positive and negative terminals that receive and send electrons.
Rechargeable batteries are more complex, however, than standard batteries. This is because the electrochemical reaction that provides power must be reversible. Care has to be taken when recharging them to ensure they perform at their best.
Frank McLarnon, Lawrence Berkley lab’s staff scientist explains it this way to Scientific American.com:
“When a battery is discharged, an electrochemical oxidation reaction proceeds at the negative electrode, and an electrochemical reduction reaction occurs at the positive electrode.
When one attempts to recharge a battery by reversing the direction of electric current flow, the opposite takes place: a reduction reaction proceeds at the negative electrode, and an oxidation reaction takes place at the positive electrode.
In the case of the rechargeable battery, the electrochemical oxidation-reduction reactions are reversible at both electrodes.
In the case of the non-rechargeable battery, when one attempts to recharge the battery by reversing the direction of electron current flow, at least one of the electrochemical oxidation-reduction reactions is not reversible.
When the battery is charged, the overall reduction reaction that proceeds at the negative electrode may not be the true reverse of the oxidation reaction that proceeded when the battery was discharged.
If the laptop battery process isn’t exact, then unwanted build up can take place on either terminal over time, which can cause a dangerous short-circuit.”
It is so important to ensure that your laptop battery or notebook battery is the one designed for your particular model and type.
Only buy Dell laptop batteries for a Dell laptop computer, Gateway aren’t compatible with Compaq laptop batteries and Toshiba laptop batteries won’t sit well in a Sony.
It is also wise to remember that old adage: “You get what you pay for.”
Some companies offer used “cheap laptop batteries” for sale, saying that they have refurbished each battery and restored most of its useful life.
The fallacy of this is that, although possible to refurbish a second-hand laptop battery, the cost to do so would be more than the price of a new battery. So, “Buyer beware,” and if you must buy discount laptop batteries, buy new discounted batteries.
Laptop computers are a boon to business, large and small. As a wise person is just about to say: “Look after your laptop and it will look after you.”
repair your laptop easy and by your self
Take care of your laptop battery and ensure that it will be ready to work properly when you need it most.
Some general tips for laptop care from LaptopRev.com include: avoid extreme temperatures, don’t leave a laptop outside in cold weather or leave it in a hot car. Cold batteries can’t create very much power and hot batteries will discharge very quickly.
Use electrical power when available to keep battery charged. Don’t let your laptop go for long periods of time without using the battery.
1. Smaller Is Better
Consider an ultraportable or thin-and-light rather than a desktop replacement laptop. Smaller displays use less power. Going with a hard drive that runs at 4200rpm uses less power than a hard drive running at 540
2. Power Control
Use as little power as possible by adjusting laptop settings. Use the Power Options to set to the laptop to go inactive after a set amount of time. Set adjustments so that the display goes off first, then hard the hard drive stay active a bit longer and store the system content’s to the RAM.
3. Turn Down the Lights
Adjust the display brightness to a lower setting, make sure you can view the screen without squinting. You can also adjust the brightness of the display to suit the conditions you are working in.
4. Watch Your Battery Use
Keep an eye on your battery consumption and know how much power you have remaining. Use the battery power icon on the system tray or you can purchase batteries which have LED gauges on the outside of the battery itself.
5. Charging It Up
Whenever you have access to a power source, charge the battery. Before you leave on any trips, fully charge the batteries, especially if you don’t know where or when you might have access to any electrical outlets.
6. Get Another Battery
Some laptops are capable of running with two batteries. If you cannot run two batteries, check with the manufacturer to see if there are high capacity batteries available. External batteries can also be used to extend operating time.
7. Drain the Battery
The first time you use your laptop with battery power, allow the laptop battery to completely discharge. Do this at least twice and don’t try to charge the battery when it is half discharged.
8. Clean Batteries
Keep the battery and its connections clean and free of debris. Clean your battery terminals on a regular basis using a cotton swab with rubbing alcohol on the tip.
9. CMOS Battery Check-Up
The backup battery is a CMOS battery which is a secondary battery to power the clock and can drain a main battery if it is dead. Check with your User Manual or manufacturer’s web site for the location of the CMOS battery and where to get a replacement.
10. Turning It Off
Don’t run programs or devices that you aren’t using. Remove PC cards and turn off Wi-Fi software. Using your laptop to watch movies or play games will drain the battery quickly as well.
Why Are Laptop Batteries So Bad?
If you are like most people with laptops you know that they are only as portable as the nearest outlet. The companies advertise like their laptop batteries make these machines so that they can go anywhere with you and there will be no problem but there is a problem.
You only have a couple hours max of normal word processing type use and then you are toast unless you either have a backup battery or you can plug in somewhere and recharge.
The other problem is that lots of places that you go and that you would love to use a laptop at aren’t able to supply outlets to everyone and so you are up a creek as they say.
So my main question for this piece is why are laptop batteries so bad?
To answer this question I am going to do a quick search on the internet and try to quickly glean as much information as I can in the next few minutes and then I will proceed to pack it in to the next 2 paragraphs or so. Here I go….
Well we will start with what most batteries are made of and that is Lithium Ion cells (older laptop batteries were made of nickel cadmium).
These batteries have several advantages including no memory and no scheduled cycling (That does not mean however that it is a good idea to repeatedly run your battery dead).
These batteries are therefore low maintenance. However because their cell oxidation can not be reversed through cycling there is a definite and short lifespan for these batteries.
This turns out to be around two to three years and is not necessarily lengthened by not using as oxidation goes on in the form of self discharge even when stored.
Now it is recommended that one stores the battery at about 40% capacity and in a cool place.
The 40% capacity gives it the ability to self discharge slowly without going all the way dead (which is bad for these laptop batteries, if you recall). These batteries will oxidize more slowly in cooler temperatures which prolongs the life.
These power cells are not meant for long term storage as already mentioned because the self discharge will drain it sometimes to the point of no return.
The reason why these new laptop batteries are so much more expensive than they used to be is because they require an internal circuit that prevents it from overcharging. Overcharging can cause the battery to heat up and actually burst into flames.
