Laptop Batteries - Why Do They Have A Short Lifespan?

If you do own a laptops you should know that they are simply as portable as the next discount store. Most companies that promote their laptop batteries manufacture these equipments so that they may be used any where and there will be no setback but there is a setback. You just have a few hours maximum of usual word processing type and then you are done except if you have a backup battery or you have a place to plug it in to revive it. Again, the other trouble is that so many places that you go and would love to use your laptop do not have enough power outlets and so you are stocked. This is just the simple truth.

Therefore, my key question is why on earth are laptop batteries so bad? In other to obtain an answer for this question, i am going to do a search online and try to find as much details as possible and then I will go ahead to pack it into the next 2 paragraphs or so. Well we will like to begin with what nearly all batteries are built of and that is Lithium Ion cells (older laptop batteries were built of nickel cadmium). Honestly, these batteries possess a lot of benefits such as no memory and no scheduled cycling (That does not mean exactely that it is a useful perception to frequently run your battery dead). In fact, these batteries are very low to maintain.

Nevertheless, just because their cell oxidation can not be changed through cycling, there is a definite and little lifespan for these batteries. This should be around two to three years and is not necessarily lengthened by not using them as oxidation goes on in the form of self discharge as well as when stored. Indeed, it is advised that we store these batteries at about 40 to 45% capacity and in a cool place. Be aware that the 40% capacity gives it the power to self discharge gradually without going dead completely (which is actually bad for these laptop batteries).

In fact, these laptop batteries will oxidize very slowly in cooler temperatures which prolongs their lifespan. Moreover, these power cells are not intended for long term storage as previously said because the self discharge will drain it every now and then to the point of no return. The basis why these modern laptop batteries cost so much than they used to be is for the reason that they do need an internal circuit that stops it from getting overcharged. Furthermore, overcharging might as well induce the battery to high temperature and as a such they could burst into flames.
