Laptop Batteries - Taking Care of Them

Do you always end up hurrying to a closed wall power outlet to charge up your laptop batteries simply so you can use it? And irrespective of fully charging prior to leaving the home, you still run low when employing it while you're out?

Taking Good Care of Your Laptop Batteries

Well, I am certain these questions make you think about how to take good care of your laptop batteries so here are some useful points.

First, when you use a laptop as a desktop computer substitute, check that you don't leave the batteries within the unit for a long time since naturally; the laptop will discharge the battery after a few hours. Nevertheless, should it occur that your battery has become discharged, remove it immediately and make sure that it is charged to half of its capacity. After which, wrap the battery in a dry fabric and put it in a warm and dry location and check that that it is in a secure place.

Re-Install Your Laptop Batteries Regularly

Exercise your batteries and put them back in on a frequent basis. This will permit them to exhaust the right way as leaving fully charged batteries inactive for a long time will fully drain them and will adversely affect the batteries' useful life. Use the batteries a minimum of every two and three weeks.

Keep The Laptop Batteries' Metal Connections Clean

Clean the metal contacts of your batteries. Do this regularly every few months using a cloth dampened with alcohol as this helps your battery to transmit power more efficiently.

Keep the Operating Temperature Low

Your laptop will function more efficiently if it is cooler. This is why you need to always inspect your air vents by making use of a fabric or a cleaning agent made for cleansing keyboards, or better yet, you can invariably look online for more helpful hints on attending to your laptop battery.

Refine Your Power Options.

Laptop Batteries - Why Do They Have a Short Lifespan?

If you do own a laptop, 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 anywhere 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 order to obtain an answer for this question, i am going to do a search online and try to find as many details as possible and then I will go ahead to pack it into the next 2 paragraphs or so. Well, we would 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 exactly 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 cannot 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 reason why these modern laptop batteries cost so much than they used to 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.
