There are many different beliefs of how you should charge your laptop battery, when you should charge it, or even where you should charge it.
A laptop battery is not going to last you forever; we all know that. However, there are a few things you can do to ensure a longer, healthier battery.
The tips that I am going to highlight in this article are not some crazy séance voodoo trick that take 3 days to perform. They are small steps that can pay major dividends to your battery life if you give the battery just a little more attention than normal.
Tip #1 - Turn laptop over and gentle blow on the back for 10 to 15 minutes daily Keep it cool
Most people overlook this one. Excess heat is not only bad for your processor (and your lap), but your battery as well. A hot battery will degrade in health much quicker than a cool one.
It is best to stay out of heat when using your laptop but it's also just as important when it comes to storing your laptop. Battery University states that the best way to store your battery is in a cool temperature. If you store your laptop in 32-55 degree temperatures and use it every day the battery will only lose 4% of its overall charge after 3 months
On the contrary, if you store your laptop in temperatures of 80-100 degrees while using it every day the battery will lose 20-30 percent of its overall charge.
Remember: You wouldn't leave your dog or baby in a hot car. Don't do it to your laptop
Tip #2 - Don't Leave It Fully Charged
If you have ever heard the 40/80 rule. It applies more towards nickel-based batteries saying that you should keep the charge between 40% and 80%. Although, that rule is said to not be direct towards the newer lithium-ion batteries it is still a great guideline.
When possible, keep it in that range to prolong its life as long as you can. And, if you do charge it to 100%, DON'T LEAVE IT PLUGGED IN. This is something most of us do, but it's another thing that will degrade your battery's health. If you need to charge it overnight, use something like the Belkin Conserve Socket to stop it from charging after it's full.
Tip #3 - Perform Shallow Discharges
Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit.
The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
Tip #4 - Fully Discharge Once a Month
This may seem contradictory, but hear us out.
While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries", which means that they can tell you how long you have until your battery dies (e.g. "2 hours, 15 minutes remaining"). This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.
Keep these 4 simple tips in mind for the next time you are complaining your battery is dying. You'll remember that you left it in your leather seated Smart Car for a week and then think about this article.
