Laptops Battery Life

The battery life and the laptop battery care is another most important topic which one must have to care so as to have longer battery life. Normally the batteries which the manufacturers provide with the Laptops are Li-Ion or Li-Polymer these are rechargeable batteries and can give you optimum backup even you are working on battery packs. But the main thing is tat how to optimize it to make it work more efficiently.

The common term when we talk about Battery in Laptops is the Depth of Discharge (DOD). Depth of Discharge (DOD) is the amount that a battery is run down to before it is put back on charge. For a notebook this can vary enormously. Many machines are only run down to 70% battery during short stints of battery power (known as a shallow DOD), others are discharged completely to 10% or 5% (known as deep DOD), this is when the notebook switches off or warns about low battery.

Now another technical aspect is the charge cycle. A charge cycle is a cycle of running the battery down and then charging it up again. One charge cycle is classified as when the battery is run down to 70% or less and then charged again to 90% or more. A battery does not have to be discharged until it is flat before a charge cycle is used.

The other main factor that affects battery life is temperature, the hotter the battery the less charge cycles it will run for, the industry suggestions are that a battery is run at between 10 and 30 degrees centigrade. It should be noted that it may be hotter inside the notebook where the battery is than in the room where it is being used.

The battery life and rechargeable ability of a particular type of batteries like Li-Ion varies but these are more than enough for you before going for its replacement. Always try to have a look at your battery packs how much backup they provide and time of full charge. This is done so as to check if the batteries are becoming old or demanding for the replacement or what. If possible always try to use Power Supply while working on Laptops.

Always carry with you an extra battery pack so as to use it when you are traveling and where it is not possible to lug in to the Power Supply. If you have found that the batteries has gone old then immediately replace it with new one and never keep the old batteries in the Laptop thinking of buying the new one. This will damage your internal circuit.
