Li-Ion: From time to time many medicines are written that aim to increase the lifespan of rechargeable batteries Li-Ion on smartphones, tablets or laptops. The truth is that if you pay a little attention you can make a difference, without this meaning that you should treat your batteries like sick pets.
They are all designed and built to do a specific job. So most of the time you need nothing more than to let them do their job.
Όμως με λίγη προσοχή, μια επαναφορτιζόμενη μπαταρία μπορεί να διαρκέσει χρόνια. Πόσα χρόνια; Από την εμπειρία μου, η απάντηση είναι "πολλά".
I have a first generation iPod touch that I got in 2008 and it still works with its original battery. Yes, all batteries will wear out, and they will not be the same as the one you purchased, but they will most likely continue to work.
What to look out for in all Li-Ion rechargeable batteries?
Κατανοήστε τον όρο "κύκλος επαναchargingς"
Κάθε μπαταρία έχει μια περιορισμένη διάρκεια ζωής που αναφέρεται σαν "κύκλος επαναφόρτισης" ή "κύκλος ζωής μπαταρίας".
Με απλά λόγια, μιλάμε για τον ο αριθμό των κύκλων φόρτισης - αποφόρτισης που αναμένεται να έχει μια μπαταρία πριν δεν είναι πλέον κατάλληλη για χρήση.
Ορισμένοι κατασκευαστές hardware αναφέρουν αυτόν τον αριθμό ενώ άλλοι αποφεύγουν να το κάνουν. Για παράδειγμα, η Apple διαθέτει αυτές τις πληροφορίες, και αναφέρει ότι η μπαταρία του iPhone έχει σχεδιαστεί για να διατηρεί μέχρι και το 80 τοις εκατό της αρχικής της χωρητικότητας σε 500 κύκλους πλήρους φόρτισης και αποφόρτισης, ενώ στο MacBook Pro ή στο MacBook Air η μπαταρία έχει σχεδιαστεί για να παρέχει έως και 1000 πλήρεις φορτίσεις - αποφορτίσεις πριν φτάσει στο 80% της αρχικής χωρητικότητάς της.
You can find out how many times your MacBook's battery has been recharged by clicking the Apple logo on the menu και στη συνέχεια Σχετικά με αυτό το Mac - System Report. From there, click on choice Power and look for Cycle Count.
For a system running Windows 8 or Windows 10, run the following command from a command prompt:
powercfg / batteryreport
The command will create a report in HTML format and save it in the account of the user who ran it.
Myths and reality:
Charging cycles
Some believe that they can avoid the charges and discharges mentioned above by systematically recharging their battery before it is fully discharged.
Unfortunately, you can not change the laws of physics. Let's see why:
Εάν αφήσετε την μπαταρία σας να εκφορτιστεί μόνο κατά 25%, και το κάνετε τέσσερις φορές, 4x25% μας κάνει 100% δηλαδή μετράει σαν ένα μόνο κύκλο. Το ίδιο συμβαίνει αν κάνετε πέντε φορτίσεις στο 20 τοις εκατό αποφόρτισης της μπαταρίας, ή και 20 επαναφορτίσεις μετά από 5 τοις εκατό αποφόρτισης.
So from the above we see that smaller charges allow us to put in the charger more times in our device.
What does this mean; But what can you do to prevent unnecessary charging cycles? It's simple and rather easy if you know the above. You can connect your devices and charge them where possible, and you can only leave the devices connected when they are in use.
It is advisable not to let them charge constantly, as this can cause heat to build up, which can damage the battery. Putting your device in the charger and going to bed should be avoided.
In other words, I'm not saying you should constantly charge your device's battery, because it also needs full charge to keep its internal chemistry in good condition. You just have to be more discriminating with the help you render toward other people.
Full or partial discharge?
Some say you should not let a Li-Ion battery run out of power before recharging, others say it does not matter.
The truth is, with modern Li-Ion batteries, it does not matter, because their discharge is regulated by the built-in circuits.
This was a problem with old NiCd (nickel-cadmium) batteries because there was a point where it would be impossible to recharge them if they were discharged. These batteries did not need to be charged very often and were much more sensitive to temperature. The same goes for lead-acid batteries.
Li-Ion: The temperature
A room temperature of around 20°C is the best temperature for him latest technology equipment charging. However, we don't all live in air-conditioned rooms, and the temperature range changes. High as well as very low temperature can damage the battery. This is especially true for charging the battery at temperatures below 0°C, which can permanently damage the battery.
Battery chemistry can play an important role. There are some batteries that have better temperature tolerance than others (check the specifications).
Exposing Li-Ion batteries to extreme temperatures can also cause distortion or cracking. This of course can also damage the device that contains the battery.
If you want to monitor the battery temperature on your laptop there are many utilities: for example the Passmark BatteryMon (Windows) or for Mac systems the TG Pro.
Li-Ion: Avoid Stress
Yes the batteries do not want to be stressed. Avoid loads that forget the device in the charger, and falls. A fall, which is something that has happened to everyone, can damage the battery, causing corrosive chemicals to leak, which in turn can damage electronics, not to mention our skin and eyes.
Do not use the device
If you do not intend to use your device for a period of time, avoid fully charging it before storage.
A charge of about 50% is what most manufacturers recommend. On the other hand, storing a discharged battery may prevent it from being rechargeable (usually due to the safety features built into the battery or charger). Storing a fully charged battery can shorten its life by causing it to swell, which in turn can damage the device.
You philosophize
After all of the above you should also be a little philosophical: Everyone dies one day! If this happens, (which will happen) please do not shoot the pianist, or in our case the columnist.
