How To Save Power Battery

Batteries are present in every device : laptop, mobile phone, MP3 player. But after a time (depending of the quality of the battery and the usage), the battery goes down, and you can only use it for 5 minutes. At this moment, you go to Google to find some advices on "how to restore my battery", but... it's to late.

Keep in mind that your battery is a consumable : you will not be able to keep it for ever. Knowing this, you can get some good practises to maximize the lifetime.

This article will teach you how to preserve your battery and how to keep it as long as possible.

Ventilate it

The battery hates heat, so when you are using your laptop at home, do not put it on a pillow or in the bed. Place something flat and rigid below it, to keep a good airing in it.

Also, get used to blow your computer regularly (1 time per year). You can go to a computer store, or buy a dry air bomb and do it yourself.

Avoid extreme temperatures

A good-temperature for a battery is between 10°C and 20°C. Below 10°C and above 20°C can damage your battery.

If you let your computer in a car, you can damage it : if the weather is sunny, your car will become a oven : high-temperatures damage your computer. At the opposite, if it's winter, your car will become a freezer, and low-temperatures damage your computer, too.

Do not use it below 10%

When you go below 10%, you are consuming a lot your battery. The whole battery is exhausted of the previous 90%, and now she has to concentrate a lot to find the rest of energy contained in it.

Take the habit to stop using the machine when it says "hey, my battery is low". At this moment, find a power supply and fill your battery.

Recharge it when it is low, because keeping the battery at a low level is bad.

Do not keep it full-charged

Keeping the battery full-charged for a long time is a bad factor. This fact is meaningful for people who always plug their computer to the power supply : if you don't remove the power supply, remove the battery with 80% in it.

As demonstrated above, there are some factors :

Intensive usage

An intensive usage of your battery is also painful for your battery, especially when the level is low.

When you are on battery, try to minimize activity : minimize the light of the screen, do not do 3D-processing, avoid video games, and so on.

Conclusion

Your battery is a consumable, you will not keep it for ever. But keep in mind those factors (temperatures, intensity, low/high levels), and you can maximize the lifetime of it.

Intéressant ! Et la fameuse histoire de la première charge/décharge complète c'est toujours d'actualité ? Ou c'est un conte pour enfant ?

@Jérem : la première décharge/recharge, ça n'est pas un mythe, c'est effectivement bon pour la batterie, car ça lui permet de "voir ses limites".

"L'effet mémoire" sur les batteries Li-ion n'est plus vérifié. C'était le cas sur les batteries de type "Ni-Cd/Mh" (accus de piles rechargeables encore de nos jours). Cependant, les constructeurs préconisent de faire une décharge/recharge complète et régulière de la batterie pour que cette dernière retienne quels sont les secteurs/cellules endommagées. L'intelligence de la batterie fera en sorte de recalculer sa capacité de charge et, à fortiori, de donner une information réelle au système d'exploitation.
