Frequently Asked Questions

Frequently Asked Questions (FAQs) about laptop batteries

1. What battery life can be expected from a laptop battery? Battery life largely depends on how the computer is used. Several factors influence a laptop's power consumption, some of the main ones being screen brightness, processor efficiency, and other core laptop components. The brighter the screen and the more demanding the program or programs you are working with, the shorter the battery life will be. Some laptops offer several hours of use, potentially up to 8 to 10 hours of battery life, while other models, with a similar capacity battery, only allow 1 to 1h30 of use.
2. What is the lifespan of a laptop battery? A battery's life is measured in charge/discharge cycles. A lithium-ion or lithium-polymer battery typically performs between 300 to 700 charge/discharge cycles during its lifetime. This variation depends on several factors, such as the quality of the battery's components or external factors, like frequent exposure of the equipment to heat sources.
3. Why has my battery's life decreased, and now it only lasts for 5 minutes? This phenomenon of battery life loss is usually related to the battery's age and the number of charge/discharge cycles it has already completed. As a battery "ages," the internal resistance of its cells increases, and its effective capacity decreases until, finally, the battery can no longer "hold a charge."
4. LXbattery offers several options for replacing an original battery. How do I know which option best suits my type of use? Normally there are several options for replacing an original battery, whether original or compatible models. Compatible models often have options with different capacities (shown in mAh or Wh). The higher a battery's capacity, the longer its possible autonomy. For your laptop, if there is more than one replacement battery option, the one with more "mAh" will have the longest battery life. This information is always available on the original battery, so you can compare it with the replacement batteries.
5. My new battery is not providing the battery life I expected. A new battery needs some time to reach its maximum performance, usually about 15 to 20 charge/discharge cycles, between 2 weeks to 1 month of use. What you will notice is an increase in effective battery life during this "break-in" period until it reaches its maximum capacity. If the battery still falls short of expectations, it should be evaluated whether there is any factor influencing the laptop's energy consumption and/or consider purchasing a higher capacity battery.

Useful tips to increase laptop battery life and longevity

1. Myths about batteries. You may have heard some advice about batteries such as only charging them to 80%, not leaving the laptop plugged in for too long (when the battery is already at 100%), or fully charging and discharging the battery between uses. This advice is outdated and applied to older battery types, such as nickel batteries, but no longer applies to modern lithium batteries used today. However, it is advisable that, at least once every three weeks, you perform a complete charge/discharge cycle on the battery, although you should not let the battery reach 0% during discharge. When it is around 5%-7%, then plug in the charger.
2. Activate power saving mode. Most "power saving" modes activate a set of automatic changes at the laptop component level that reduce its energy consumption.
3. Disable unused components and ports. Every laptop component needs power to function; start by disconnecting unnecessary peripherals (USB mice, external drives, etc.) and others you don't need at the moment, such as Wi-Fi or Bluetooth, graphics processors, etc. Attention (!), before disconnecting any component, make sure you really don't need it.
4. Adjust your settings. Reduce keyboard backlight or screen brightness. Additionally, if you are simply typing a document, maximum screen resolution may not be necessary. Reducing screen resolution also adds some extra battery life. If you are not listening to anything, you can also mute the laptop speakers.
5. Close applications and processes, and simplify. It's not just hardware that consumes power; software also significantly impacts a laptop's consumption. As with hardware, start by closing programs that are not in use. Simplify, because having several programs running at the same time will consume more power.
6. Reduce streaming. Change how you listen to music, from an external source, streaming for example, to playing files saved on the disk.
7. Give the battery a rest. If your computer has a removable battery and you are using the computer for a period where you don't need it as a "portable" device, having access to electricity, then you can remove the battery. Always be careful not to damage the battery contacts. Also, remember that this procedure has the drawback that, in the event of a power failure, the computer will shut down abruptly.
8. Promote good ventilation. Heat reduces battery longevity, so ensure good ventilation at the base of the laptop. Periodically clean the laptop fan and do not use the laptop on blankets or cushions.
9. Upgrade laptop components. Replacing the classic hard drive with an SSD results in significant improvements, both in battery life and computer performance. If you prefer to keep the hard drive, then perform periodic defragmentation.
10. Have supplementary power. If your battery's life is not sufficient, then consider purchasing a supplementary battery or a power bank for laptops, which usually come with various tips for different computer models.

 

How to change/replace your car battery?

It's not a difficult task, but it requires some specific care.
Here's a small tutorial to help those less experienced.
Batteries are similar and all consist of a positive and a negative terminal. Depending on the size, the weight of a battery usually varies between 10 to 25 kg.

Why learn to change a battery?
First of all, you never know when you'll need to change yours. If you think taking your car to a mechanic to change the battery is overkill, that the labor for the service is expensive, or if you suspect the mechanic might install a used battery, then this tutorial is for you.

Steps to change the battery:
Important note: The positive and negative terminals of the battery should never touch each other, to avoid short circuits.

Step 1
First, you will need the equipment listed below:
- A new battery (you can find the correct battery model for your car by searching through our filters, or contact us through our support line).
- Personal protective equipment (gloves and safety glasses)
- Spanner wrenches nº10 and/or nº8.
- Socket wrench nº13 with extension.
- Steel brush for cleaning.

Step 2
With the car engine off and the key out of the ignition, loosen the nuts on each terminal, using the appropriate spanner wrench (usually nº10 or nº8), starting preferably with the negative terminal (black), and then the positive (red). The nut does not need to be completely removed to lift the terminal from the battery post.
Next, you should loosen the battery fastening device. Usually, in European brand vehicles, there is a fastening plate at the base of the battery whose nut should be fully loosened and the plate removed (a socket wrench nº13 with an extension is usually used).
In the case of Asian brand vehicles, the battery is usually secured by an upper fastening plate, which should also be removed (usually using spanner wrenches nº10 and/or nº8).

Step 3
Carefully clean the cable terminals with a cleaning tool, for example, a steel brush, until the terminals are clean and free of corrosion residue. With a brush, clean these corrosion residues. If the cable terminals are not in good condition, they will need to be replaced.

Step 4
After removing the old car battery, place the new one in the same spot and reverse the procedures.
Place the positive cable terminal on the positive (red) battery post and then the negative cable terminal on the negative (black) battery post. Make sure the screws are properly tightened, without over-tightening. Close the car hood, start the car to test for correct ignition.

We hope these tips can help, it's true that for some people this information is basic, but for most, a little information is always good!
In case of doubt, you should request appropriate technical support from qualified personnel.
