What You Should Know About Replacement Batteries

If you need to be connected to a power outlet to be able to work for only 30 minutes, that is no longer a laptop.

Surfing the Internet, I have come across a lot of questions from users from all over the world, but there was one that left me with a big question: Why do we have to change the battery of our laptops frequently?

For some reason I was not left with the doubt and I decided to investigate, indeed I found a very peculiar answer; a user answered “Because the manufacturers classify them as consumables”.

I could not believe it! When I saw this I continued investigating and certainly, the Apple brand considers that the battery is a consumable and for that reason its wear is not covered by AppleCare, unless it is a defective battery. 

Similarly Dell considers batteries as consumables, despite their many warranty coverage rules, they do not cover short term wear and tear, this is considered normal, unless, as I mentioned before, it is a defective battery.

Perhaps you have already taken a dip in the Internet and explored various online stores to review the different models that you can find, all batteries are generally very good, but you should analyze some points before making your purchase, criteria and above all, features that you may need to know before making the decision to purchase a battery for your laptop.

If you are not an expert of the subject, then this might interest you, so, get comfortable and take note, because everything mentioned here will serve you much more ahead.

What Are Laptop Batteries and How Do They Work?

It is called battery or accumulator, to the device that stores energy using electrochemical procedures and that later returns it almost in its totality, this cycle can be repeated a certain number of times.

Laptop batteries are made up of batteries (also called cells), which are connected together in series to increase the administered voltage. In general, laptop batteries are usually made up of 6 cells, each of which supplies electricity with a voltage of about 1.8V – 2v (although they are never exact), so that together they deliver 10.8/11.0V.

It all depends on the voltage and the number of batteries, the total battery may vary.

Batteries can have several voltages and several sets of batteries or cells.

There are batteries that contain 3 cells, 6 cells and 9 cells.

Likewise, there are also batteries with different voltages: 7.2 V / 7.4 V / 10.8 V / 11.1 V / 14.4 V / 14.8 V. 

When Should I Replace the Laptop Battery?

This will always depend on the brand, laptops do have a program that is responsible for monitoring the status of the battery, a criterion that you can take as a reference is the following: “Can your laptop stay on for at least half the time compared to when it was new?

Tips or rather, conditions that you should evaluate are the following:

If you need to be connected to an electrical outlet to work within 30 minutes, it is no longer a laptop, it has become a desktop computer with some mobility.

In our modern times the average life of a laptop is approximately 5 to 7 years, but it is very likely that after 5 years of use, the manufacturer will stop producing parts for that model, so this is where you should start thinking about replacing the battery or purchasing a spare, while they are still available.

Knowing the Date of Manufacture of the Battery

It is important that you do not be fooled by the low prices that you can find in various online stores, maybe you can find the battery you need for a price less than 100 USD, big mistake!

Remember that well says the phrase “cheap is expensive”.

This is very true, because taking as a reference the year in which we are, they can sell you a battery that was manufactured in 2012, that is the most likely reason why the price may be low, so it is better not to be guided by the economy that you see, because the batteries that are stored for long periods, can deteriorate for lack of use. They can even offer you recommendations on the level of charge and how to store it so that it wears out as little as possible.

Model

Keep in mind that a single battery model can be functional for many other laptops and even for other brands. For that reason it is important that you check the Part Number that is silk-screened on the battery label.

The most convenient and safest thing you can do when buying a battery is to do it by the model, once you locate what model your laptop is, you should focus on the voltage.

Voltage

It is of great importance that the voltage of the battery that you are about to acquire is the same voltage that your laptop needs. In the case of batteries with 10.8 V or 11.1 V both models are compatible, they work indistinctly. But if your laptop uses a 14.4 V or 14.8 V battery, we can NOT use a 10.8 V / 11.1 V battery.

The battery voltages that you can find in the market are: 

  • 7.2 V / 7.4 V
  • 10.8 V / 11.1 V
  • 14.4 V / 14.8 V
  • 15 V / 15.4 V

MilliAmperes Are They Important?

As you will notice, the capacity of the batteries is measured in mAh (milliampere hours), which is the capacity of the battery to supply energy to our computer so that it can work properly without being connected to the electric current.

See Also: Laptop RAM Review

There are 2200mAh / 4400mAh / 5200mAh / 6600mAh / 8800mAh / 12000mAh batteries. Remember that the more mAh capacity the more autonomy our laptop will have.

Normally the batteries that are included when you buy a new laptop range from 4400mAh capacity or other equipment usually bring 2200mAh.

It is advisable that before you make your purchase, check on the silkscreen of the battery, how many mAh it is, because later it will serve as a guide to avoid making a mistake when choosing and you have to regret it later. Take note of this and you will make a safer purchase.

Battery Life and Charge Cycles

Lithium-ion (Li-ion) batteries generally have a lifespan of 300 to 500 cycles. With moderate use we can make them perform up to 60% longer than expected. Batteries wear out or lose their capacity over time, therefore, after a year or two, they usually reduce their life, all this depends on the use you give to the battery.

If in your environment there is a higher or lower temperature during operation can result in a loss of 70% of its capacity. Therefore it is always recommended not to leave a battery exposed to the sun, or in extreme heat or cold environments. This is for the safety of you and your laptop.

The rate at which your battery discharges will depend on your laptop’s power management settings and also depends on the applications that are running.

The number of times your battery is fully charged and discharged is also a factor in performance.

Internal Elements That Influence Battery Consumption

For your battery to have a good performance and long life, you should know some factors that come from the system of your laptop, and that have as a consequence, the higher battery consumption.

As you know, it is not the same to use your laptop and work with a Word document, which does not consume much battery, or to be surfing the Internet (where the workload of the components is much lower) to run a game that requires a lot of power and therefore greater workload for the system, as a result generates a higher power consumption from the battery, if the laptop is not connected to the mains.

Some elements that generate higher power consumption are:

  • Processor (CPU)
  • Graphics card (GPU)
  • Ram memory
  • Type of hard disk (HDD or SSD)
  • WIFI
  • Bluetooth
  • Speakers
  • CD/DVD drive or burner
  • Screen brightness
  • WebCam
  • Applications with higher power consumption: 3D games with higher graphics, applications for graphic design, video editing, image editors.

Applications with lower power consumption: Office suite, PDF, Internet browsing, music playback.
