Notebook computers. At this point in the 21st century, they have become an indispenable part of many people’s everyday lives. From the commuting business executive and the busy college student, we all want to be mobile with our computers. The big drawback of that is the fact that there is not always a plug around when you need one. A notebook computer’s battery is its life-blood. Without proper care, your notebook battery could fail much earlier than anticipated. By following a few simple steps, you can expect to get the greatest amount of usage possible out of your notebook battery before a replacement is needed.
1. Upon purchase, charge the battery to full capacity. Whether you have purchased a new computer have purchased a new battery for your laptop, charging it fully as soon as you open the box is the best recommendation. This allows the battery to reach a full capacity before you begin to use it “unplugged”. Most batteries come with a partial charge, enough to get you going if you absolutely had to. Giving that battery a full charge when it is brand new will help set the charge capacity for the battery at its highest possible level.
2. Once you reach a full charge, leave the computer plugged in for at least 2 hours. This action lets the battery “rest” at a full charge for a fairly lengthy period of time. At this point, the battery is not drawing power from your wall socket to charge, and it is also not supplying any power to your system. Letting your battery rest for a time after a full charge helps to “lock-in” that full charge capacity.
3. Unplug the computer and drain the battery. It might sound silly, but now that you have gotten that battery to a full charge, you need to drain the power almost completely. Again, this will help determine the charge capacity of the battery. Leave your computer unplugged and use it until you get a warning telling you that the battery is almost completely discharge. Then save whatever you are working on and power the computer down. Plug back into the wall socket for a fresh charge. Then use the computer at your leisure.
If you follow these steps about once a month, your notebook battery should last a nice long while. Not to say that you will never have to replace it, but at least it will be a long time before you need to.

Will Bio Batteries Over Smart The Commercial Batteries
Due to global warming conservation of the environment is the need of the hour .Hence various bio changes have been made over the commercial ones. One such discovery is the Bio Battery.
Concept behind the latest Bio battery:
Every battery has an anode and a cathode which aid to produce electricity at the expense of chemical reactions. However in these bio batteries glucose molecules are consumed to generate electricity. The anode of a Bio battery contains sugar digesting enzymes and a mediator to connect with the source. The cathode of the battery contains oxygen reducing enzymes and mediator. A cellophane separator is used in the Bio battery to separate the electrodes. Glucose molecule produces hydrogen ions and electrons due to the process of enzymatic oxidation. At the end of oxidation glucose molecules are converted to glucano lactones, hydrogen ions and electrons.
Then the hydrogen ions move through the cellophane separator to the cathode. Hydrogen ions and the electrons react with oxygen and produce water. These electrochemical processes generate electricity, when the electron passes moves through the electric circuit.
The electricity generation process in the Bio battery is very simple when compared to the other commercial batteries. At the same time these Bio batteries use a renewable resource like glucose to generate electricity. Most of the commercial batteries consume non-renewable resources to generate electricity. This makes the Bio batteries to oversmart the commercial batteries.
Key features of this bio battery research and development:
1) Principle behind on how to induce the mediator and the immobilization process:
Bio battery has a specific principle to induce the enzyme immobilization process and the mediator. The anode should have oxidizing enzymes and the mediator both in high concentrations, to oxidize the glucose molecules effectively. This increases the efficiency of the process. Two polymers are used to attach the enzyme molecules and the mediator to the anode. The charges of these polymers are opposite to each other. The electrostatic interaction of these polymers induces the binding of the molecules with the anode. Optimized ionic process induces the effective use of elect

rons.
2) Structure of the cathode:
The intensity of water present at the cathode ensures the efficiency of the enzymatic reduction process. Porous carbon electrodes bear the mediator and immobilized enzyme. Cellophane separator used acts a partition between the electrodes . The optimized electrodes maintain the water level at the electrode surface and it induces the cathode reactivity.
3) Optimization of electrolytes:
Normally 0.1 M phosphate buffer is used in all kind of enzymatic reactions. High concentration of phosphate buffer increases the efficiency of the Bio batteries. 1.0 M concentration phosphate buffer is also used in Bio batteries. The concentration level can be determined only based in the process of maintaining the enzyme activity on the electrodes. At a higher concentration level the Bio batteries generate more electricity.
4) Test cell is combining compact size and high power output:
Bio batteries require sugar solution to accumulate glucose molecules at the anode surroundings. These Bio batteries do not require any complex solutions to act as electrolytes, a simple sugar solution is enough to generate electricity. A Bio battery generates electricity up to 50 mw, highest output among the all kinds of passive batteries. By connecting a series of cubic cells, you can increase the power output. This is an eco friendly product, the body of the cell is made up of natural plastic polyactate (plastic produced from the vegetables), since its is biodegradable.
The above said features make the Bio batteries to over smart the commercial batteries. Most of the commercial batteries use chemicals, which are very hazardous to the eco system. These bio batteries are very easy and more efficient to use when compared to the normal commercial batteries.
