Today, the portability of a gadget is the main reason customers purchase laptops. The portable computer is always ready to help you with business or studies. It is quite easy to carry and use while on transport, at the seaside, in the park, etc. but, as you know, there are some problems connected with laptop battery calibration and recovery.</p> </p>
How to understand when a battery needs to be restored</h2> </h2>
Likely every laptop user has at least at once faced a problem connected with their laptop battery. If not, be sure one day it will happen, because in most cases, a battery is the first thing that fails on the laptop. The laptop battery is a component which has a restricted energy reserve and it’s considered great if it works more than 5 years.</p> </p>
Usually, the battery loses its capacity over time and even a full charge allows the laptop to work less and less. Also, there are some situations when your laptop doesn’t power on and the battery is not charging. Quite often laptop users ask what to do when my laptop battery is not charging? How to restore a laptop battery at home? Answers to these and many other questions will be discussed in this article.</p> </p>
Before starting the repair, it is important to know when it is needed. Most laptops these days use lithium batteries and now we will talk about this type.</p> </p>
</p>
- The battery’s elements have lost their resources. Sometimes not all the elements are missing, just some of them. In such a case, you’ll need to remove old elements and insert the new ones.</li> </li>
- Battery elements are completely out of charge. That means that battery elements are OK, but the battery controller blocks the charging because of low voltage. In this case, you need to balance the elements. A little bit later we will tell you how to do this.</li> </li>
- The controller is broken. Likely it needs to be replaced. </div>

When laptop battery recovery is impossible</h3> </h3>
Obviously, no battery is good forever. Sooner or later every laptop owner has to purchase a new one. Let’s consider some cases when it may prove impossible to repair your laptop battery:</p> </p>
- If none of the attempts to recover the accumulator has given any result.</li> </li>
- If the battery had exploded because of incorrect actions or storing conditions.</li> </li>
- Wrong identification of the battery’s type. There are several types and almost each of them requires an individual approach and methods while the process of reconditioning.</li> </li>
- After 3-4 years of usage. All the batteries have restricted term of usage and the capacity will slowly diminish over this time period.</li>
</ul>
Actually, laptop producers claim that the battery is able to be charged and discharged about 400-500 times (3-4 years). However, this depends on how much the computer is used and how long it is left on.</p> </p>
After the number of cycles has reached 400-500, the capacity decreases twice. And the length of time the battery can handle becomes about an hour or even less. When this happens, it is better to buy a new battery.</p> </p>
Of course, the laptop battery restoration may help it to live a little bit longer. But such an approach just won’t compare to a brand new battery.</p> </p>
The laptop battery types</h2> </h2>
Different brands use different materials and technologies while producing their laptops and batteries. There are two basic types: nickel and lithium. Let’s have a more detailed look at each type:</p> </p>
Nickel batteries</h3> </h3>
Nickel-cadmium (NiCad);</p> </p>
Nickel-metal hydride (NiMH).</p> </p>
NiMH has a higher capacity in comparison to the nickel-cadmium battery, which has the same sizes. This type of battery is much more environmentally friendly and that is quite important nowadays. One more advantage is that these ones are not so influenced by the so-called “memory effect”.</p> </p>
What does it mean? Memory effect is a result of different chemical reactions inside the battery, that make it “accustomed” to the level of wasted energy during the last charge cycle and equals the capacity according to the level of regular energy-waste. As a result, every following charge will lead to a lower and lower level of energy inside the battery. After some time, it will lead to enormous decrease of the charging limit. Memory effect is common only for NiCad and NiMH batteries. But now all the gadgets are being produced with lithium ones.</p> </p>
Lithium batteries</h3> </h3>
Lithium-ion (LiIon).</p> </p>
Available in 30% smaller sizes, the Li-Ion batteries have a much higher capacity for energy than the Nickel-Metal Hydride ones. The main problem of this type is that they are rather sensitive to high or low temperatures. In the heat or cold, their capacity can be extremely decreased. Also, the price for such batteries is quite high in comparison to the other types.</p> </p>
Lithium-polymer (LiPol).</p> </p>
This is the most modern kind of battery, which hasn’t fully caught on yet. Developers have solved the problem of temperature resistance. Also, LiPol-s are much safe and long-lasting than previous types. Now the latest models of laptops are equipped only with lithium –polymer batteries.</p> </p>
How to identify the type of battery?</h3> </h3>
Each type has its own features and internal quirks. So, before starting to fix a laptop battery, it is important to find out what kind is it. It is quite easy to do. All you need to do is eject the battery, turn it to the opposite side and find a special marker with a sign corresponding to the type.
In most gadgets, there are used Li-Ion batteries and this is the most likely result for your laptop, as well.</p> </p></p> </p>
Why is the laptop battery not charging?</h2> </h2>
As you can see, a lot of users face the problem of a non-charging laptop battery. The problem may be connected not only to the battery but also to your gadget’s software. Before buying the new charger it is important to be sure that the problem is actually the batttery, not something else. Let’s look at the main reasons a laptop battery might not charge.</p> </p>
