Have you ever wondered what is the current battery mAh’s capacity of your laptop compared to the original capacity when you first bought it? Here are 5 simple software that will calculate your current capacity and display the original capacity of your notebook. Modern batteries are more durable, thus it doesn’t make any sense to replace them if it has a 50% capacity, unless you are always on the go.

There are three main types of batteries used in modern laptops, they are nickel-metal hydride (NiMH), lithium ion (Li-ion), and lithium polymer (LiPo) batteries. Long story short, lithium polymer is the best among the three. To increase a battery’s lifespan, avoid extreme heat in temperature, battery operates more efficiently when cool, and also refrain from keeping their batteries plugged in all the time, as this significantly reduces the overall lifespan of the battery.
How To Calibrate Laptop Battery ( Or Smartphones )
If you always charge your laptop or smartphone before it is fully discharged, you will not damage your battery because modern batteries are designed to be used that way, the only problem you will face in the long run is accuracy of the battery life. This is why you must calibrate your battery after a year or two. No software or app required. To calibrate your device’s battery:
- Discharge your phone fully until it turns itself off.
- Turn it on again and let it turn itself off until the power button doesn’t respond.
- Plug your laptop / smartphone into a charger and, do not power up your laptop or smartphone, let it charge until the on-screen or LED indicator says 100 percent.
- Unplug your charger – done. Your battery is not 100% calibrated.

Sir,
Please refer to your advice quoted below – So do you mean I should take battery out from laptop when I am working on my laptop plugged in AC power socket. In fact I rarely use laptop away from power socket so my battery is 100% charged.
“However, as said in the manual book, do not leave a fully charged battery plugged in at all time to the AC power, this will damage the battery and its capacity. Happened to my Motorola phone (Charged while I was sleeping) and Acer Laptop (Battery is always slotted in with the AC Power on).
Never over charge a bettery!”
Robin,
The author is correct. One of the worst things you can do to a laptop battery is continue charging it at 100%. You’re invoking a mechanical cycle (when the battery realizes it is at 100%, it breaks the circuit) over and over again, which tends to wear down the battery quite quickly.
Believe it or not, it is better to have an additional battery cycle (i.e., from 100% to 0-5% and back to 100%) than to leave it plugged in for that duration.
@Anthony – That’s a common myth, a lithium battery is not continually charged when the device is plugged in. Lithium batteries cannot be trickle charged as lead-acid batteries, unless with “extremely low” current, otherwise it can be damaged, catch fire or explode. Most devices will stop charging the battery when full and just use the external power. It’s actually one of the best things you can do to your battery. While it will be degraded by keeping a 100% charge, it will be degraded less than discharging/recharging. Using your battery is what really degrades it. I tested it over the years, both with laptops and smartphones, and there’s whitepapers of batteries manufacturers confirming this. I’m a computer technician and usually see laptop batteries going bad after a year or two because of this misconception. My laptop (Lenovo\original Sanyo Battery) is from 2010 (8 years old) and is constantly plugged in. According to AIDA64, it’s current “wear” is just 24%, just 3% a year, actually around 4% a year (30% total) because it withhold 46Wh when new, while it’s designed power rate is 42Wh, almost 10% more (that’s common in Lenovo laptops). My customers laptops/smartphones has 30% or 40% wear after 2 years because they believe this myth and used their devices unplugged all the time. Deep discharging a lithium battery is one of the worst things you can do to it. Even when I use battery power I never allow it to go under 25% charge.
