The point is that new computers use lithium-ion batteries, which don’t have the “memory effect” that older nickel-cadmium batteries did. In fact, you should try to avoid completely draining your battery. Lithium-ion batteries last longer when partially charged and discharged.
Myth 2: Always plugging in your laptop will drain the battery.
Truth: Today’s computers know when the battery is full and stop charging. But keeping your laptop plugged in all the time puts a lot of strain on the battery (high power), shortening its lifespan. Usually it is best to let the battery drop to 40-80% before recharging.
Myth 3: Charging your laptop overnight will overcharge the battery.
Laptops are even designed to prevent overcharging. When the battery is fully charged, it will stop charging until the voltage drops below a certain value. Leaving your laptop to charge overnight will not overcharge the battery.
Myth 4: Using your laptop while charging will drain the battery faster.
Using your laptop while charging is not a bad thing for your battery. The only problem that may arise is that the laptop may become warmer during use, especially when performing high-performance tasks. Over time, this can slightly degrade battery performance due to thermal stress.
Myth 5: Make sure your laptop is always fully charged.
Truth: Leaving your laptop battery fully charged for extended periods of time can damage the battery. If you do not plan to use the battery for a while, it is best to charge it to approximately 50% capacity. This amount of power reduces the load on the battery and extends its lifespan.
Myth 6: Never use chargers from other companies.
Truth: It’s best to use the charger that came with your laptop, but using a charger from another company isn’t always a bad thing, as long as it matches the voltage, amperage, and connector type of the original charger . But an inferior charger can damage your battery or your laptop.
Myth 7: Batteries don’t work well in cold weather.
Cold weather can temporarily harm a battery’s performance, but usually does not permanently damage the battery. It turns out that high temperatures are more likely to damage batteries than low temperatures. However, don’t leave your laptop outside when it’s freezing.
8: If you have more batteries, it will work better
Truth: Adding more cells to a battery can make your laptop last longer on charge, but it won’t always make your laptop work better. The design and type of battery and how energy efficient your laptop is can affect how well it works.
In summary
Knowing the truth about these myths can help you take better care of your laptop battery and ensure it works well and lasts longer. Be sure to consult the manual that came with your device for specific maintenance instructions, and try to use the accessories and methods recommended by the manufacturer.
