What’s the optimal way to charge the battery from your laptop?

It is one of the greatest mysteries in the universe: How often – and for how long- do you REALLY need to charge the battery of your laptop? We know that batteries deteriorate over time, but there are certain things we can do to extend their lifespan.

We know that technology improves with the passing of each generation. “Now the useful life of a battery is between 3 and 5 years, in which it can complete up to 1000 charge cycles,” says Ashely Rolfe, UK Chief Technology Officer at LENOVO.

“Letting a laptop battery always charge to 100% is safe, but it will affect its useful life a bit,” says Wolfe. Laptops made by LENOVO use sensors and control logic to ensure they don’t overload or overheat. “

Phil Jakes, LENOVO’s chief engineer and chief technology officer, agrees with Wolfe. “With the higher density chemistry adopted in recent years, we found that batteries degrade faster if they are held at full charge in high temperatures.”

Given this, the question arises that we all care: how should I use a laptop?

“The one hundred percent of the charge (100%) is the heaviest condition for a laptop and its battery could degrade because this is the highest voltage. If the battery is kept far from 100%, it could be much better preserved, ”explains Kent Griffin, a technology researcher at Northwestern University.

The company HP, a leader in sales of computers and laptops, agrees. “Most new batteries have the technology to avoid overcharging once they reach 100%; however that does not prevent the higher state of charge from creating an additional voltage that increases the deterioration of the battery. “

The recommendation of these experts is to limit the amount of time the laptop remains fully charged or instead of charging it up to 100%, only charging up to 80% each time it is plugged in. “Batteries are happier with 50% charge, while they suffer more stress when they are at 0% or 100%,” says Rolfe.

The Microsoft Company, another giant of the technology industry, also alerts on its website that its Surface Laptops specifically lose capacity quickly when the batteries are constantly at their maximum charge. “You can prevent this deterioration by not leaving your laptop connected for long periods. If you need to keep your laptop plugged in continuously, we recommend that you use the limit mode for battery charging.”

HP is one of the brands that already have a configuration for its equipment called “Maximize the health of my battery”, which allows it to be charged up to 80%.

Although these recommendations make us run to unplug our equipment every time they reach 100%, LENOVO asks that we remain calm. “All laptops have control circuits to protect the batteries and prevent overcharging. Leave your laptop 80% charged and you will be fine. “

Laptop batteries, which are made of lithium, last so long that it’s not worth losing sleepover.”If you need to use it and you don’t have close access to an outlet, charge it to 100% before you leave home. If the laptop is going to stay on your office desk, put a charge limit on it”. Do what you have to do and ¡ don’t worry about it anymore!

Even better news is knowing that everytime the battery of your laptop dies and needs to be replaced, you can count on eSmart Recycling to take care of the recycling of batteries, laptops and any other electronic device, save them from the landfill, nearby water sources, or even worse, polluting the air. Whether it is one battery, a handful, or hundreds of them due to a technology upgrade or refresh, trust the experts on IT Asset Disposition to handle your end of life equipment at the highest compliance standards.
