6 Rumors about Laptop Batteries You Need to Know Before Buying

Increasing the lifetime of your Laptop battery is greatly based on us practicing famous life support advice. The things that we were asked to follow what if they were incorrect? That could be the problem with your laptop and its battery. So, to take better care of them, let’s debunk the 7 most famous fables about laptop computers’ batteries.

Rumor 1

When it’s charging, using the laptop can lessen the battery’s lifetime.

A famous myth that even your IT guy in the neighborhood will tell you. This is considered the main reason for their short lifetime.


While you’re busy at work, keeping your equipment plugged in doesn’t lessen its lifespan; rather, it’s the heat. It is arguable although that plugging in heats the battery up quicker, but in reality, the heat is because of the high workload use. The overworking processor is what causes your device to become intolerably warm sometimes.

Rumor 2

“Over-charging” your battery will make it a desktop computer.

You may have noticed that sometimes notebooks are not able to turn on when unplugged. Does it mean that laptops are now desktop computer?


NO. Opposite to famous belief, your battery neither gets “addicted” to AC power or AC adapter nor does it follow a charging/discharging pattern. Charging after a laptop is already charged is a contradiction since the new batteries offer a feature of no more charging when the battery is fully charged.

Rumor 3

If you charge it after full charge, you will damage the battery.


This is another long-circulating technological misconception. Today’s computer batteries stop charging as soon as it becomes full because they are designed with internal circuits which stop the overcharging of batter, which could have caused burning in previous devices. Batteries overheat now if the system is flawed itself.

Rumor 4

Changing flawed batteries is simple.

All big companies, on their website, sell replacement batteries for their equipment. Before ordering these replacements, you should know one thing.


Replacing your battery isn’t as simple as it seems. If you are unfamiliar with the technical aspects of the battery, you may simply order the incorrect model. If you own an Apple laptop, it gets even more complicated. Unless you’re a licensed IT professional, you are unable to replace them yourself because they come with built-in batteries. You will have to see if your equipment is out of your warranty, or you may be charged if the developer supports end-users like you to send back your device to be fitted with new batteries.

Rumor 5

Charge the battery to full power immediately.

This myth probably still applies if you own gadgets that run on the previous batteries. However, you shouldn’t wait for it to follow by the same rules because we’re talking about notebook batteries today.


If your device’s manual says that it has lithium-ion (LI) batteries, it is not important to stick to this tip. Almost every new battery is self-calibrating and is set so you can use the device as soon as you power it on. It’s still good to charge the device beforehand to make a proper calibration, which is a process for the system to determine how the battery must act. 

Rumor 6

Wait for it to run low before you charge your laptop battery again.

This only applies to old battery technology. The latest notebook computers work a lot better than their predecessors.


New batteries live longer if you never let your batteries drain fully. Such extreme discharges may confuse the laptop, and the laptop will start showing incorrect estimations on how long the battery may last. So, make sure that you are aware of these myths before you make a laptop purchase.
