Can You Overcharge a Laptop?

Overcharge a Laptop

In short, the answer is a big NO.

However, while it’s not possible to overcharge a laptop but improper usage can definitely shorten the battery lifespan. Additionally, overcharging could result in overheating of the internal circuitry, which you wouldn’t want.

To know how long your battery can retain a good charge, or whether you can overcharge it, you need to look at the type of battery your laptop is using. Most laptops and other portable equipment use the lithium-ion battery. They cannot be overcharged. However, other types of batteries, like nickel-cadmium ones, can. Let us take a look at what is the difference between the two.

When Did Nickel Cadmium Batteries Become Popular?

Until the 1990s, most portable devices used nickel-cadmium battery. What worked for these batteries were a number of things:

  • Easy shipping and these don’t require special preparations for the same.
  • Low cost
  • Good load performance
  • The batteries survived well even in cold conditions.

The biggest problem with nickel-cadmium battery was that they have a self-discharging nature. With rising concern about the environment, and toxicity inherent in Ni-cd batteries, it became a task to find a way to dispose of them easily.

Dump grounds for their disposal are not easily found and as a result, many countries have either banned or taken measures to slow down production and supply of Ni-cd batteries.

Ni-cd Batteries Can Be Overcharged

It’s worth noting that Ni-cd and nickel metal hydride (Ni-MH) batteries can be overcharged if they go through too many cycles of charging and discharging. But, the contagious charging and discharging leads to the reduction in the battery’s effectiveness and capacity.

Does Your Laptop Contain a Lithium-Ion Battery

In the 1970s, first non-rechargeable lithium metal battery hit the market. Lithium is the lightest metal known for its prolific electrochemical potential.

In order to make rechargeable batteries, non-metallic lithium batteries were released in the market which were again a big hit. And today, we use lithium-ion batteries for the majority of the purposes and applications.

With lithium-ion batteries, you don’t have to worry about causing harm to the environment.

What Happens When You Charge Your Laptop For Longer Hours?

When you leave your laptop plugged in even after the full charge, the internal circuitry of the lithium-ion battery ceases the charging process.

These batteries never get affected by overcharging. Remember, lithium batteries can’t be overcharged but they don’t get bruised on overcharging. The basic reason of high stamina of lithium-ion battery is the presence of an internal circuity.

In the absence of this, the battery may get over-heated and may possibly burn when overcharged. The internal circuitry prevents the battery from heating and if your battery gets warm while charging, simply remove it. Your battery may be defective!

The only situation when a lithium-ion battery overcharge is when the internal circuitry glitches and the battery start to heat up while charging.

The Other Advantages

It’s not just the capacity to hold on to power that works to its advantage.

  • Lithium-ion batteries possess twice the energy density to that of Ni-cd battery.
  • The load characteristics weigh reasonably same as the Ni-cd battery.
  • Also, a single cell of the lithium-ion battery of high voltage can be used for all purposes rather than embedding three cells of 1.2 volts of Ni-cd battery in series.
  • Although lithium-ion battery also has the self-discharging capability, it’s nominal or negligible when compared to the Ni-cd battery.
  • No scheduled cycles of contagious charging and discharging is to be performed for boosting up the battery life.

Charge Your Laptop For Longer Hours

Next question that arises here is, how can you boost up your laptop’s battery life?

With a few simple and achievable precautions, you can still boost up the battery life.

If your laptop uses a lithium-ion battery, never let the battery drain below 20% and keep its charging percentage between twenty and eighty. These batteries are subject to aging.

If you’re not going to use your laptop for a long period of time, simply keep the battery fifty percent charged, neither more nor less. This will reduce the aging effect. If you leave the battery discharged for a long time, it may lose its charging capacity.

On the other hand, Ni-cd and Ni-MH batteries require complete discharging and complete recharging to improve their overall performance and life.

Other precautions that can be taken are:

  • When you purchase a new laptop, charge it for at least twenty-four hours before use.
  • If your laptop is plugged into the wall, remove its battery.
  • If you’re not going to use your laptop for a long time, remove the battery. You could remove it after charging it to fifty percent to get the best results.
  • If the storage of the battery is done for a prolonged time, try to occasionally charge the battery even if it’s not in use.
  • Store the laptop under normal temperature conditions. Avoid exposing it to extreme hot and cold weathers.
  • Use system settings in order to generate reminders whenever your laptop battery drains below twenty percent.
  • Try preaching airplane mode when you’re not subjected to the use of the internet, Bluetooth, FM radio and NFC sharing.
  • It’s a good idea not to overcharge your laptop. However, it’ll not harm your laptop’s battery if your device runs on a lithium-ion battery.

If the internal circuitry of the battery malfunctions, the laptop may get overcharged and lead to overheating. This is an undesirable action, and one must remove the battery at that moment itself. Another aspect is that lithium battery’s capacity demolishes in cold weather. It must be heated up in order to charge and serve the desired work.

So, keep your device safe and don’t try to overcharge thinking that you’ll be able to use it more. Overcharging will unknowingly lead to a decline in the battery life if it’s practiced on a daily basis.
