Do you need a new laptop battery? Is your laptop’s battery performing at 100% load? You ought to know by now that all batteries tend to lose its rechargeable capacity or load when used frequently. This may not be important for those who already own these laptop, however, as a secondhand laptop buyer, you may want to know the status of the battery. How to perform a rechargeable battery test?
Imtec Battery Mark is a laptop battery test software. As the name implies, it uses a simple algorithmic to calculate possible notebook battery life and capacity. By using the forecast Windows Time and divide it with the original capacity time, you’ll roughly know the status of the battery.
The program is designed to test the battery laptop. Some features:
- At the time of testing construct a detailed schedule of changes in the level of battery power. After testing all the data stored in a log file for later viewing and / or analysis.
- After the testing, the total assessment system power notebooks, calculated by a unique algorithm, taking into account not only the time of the battery, and laptop performance during testing.
How To Extend Laptop Battery Life
From what I understand and read off the manual books from both my Nokia handphone and Sony Laptop, today’s batteries canbe charged regardless of its current capacity. Meaning to say if it is 50% charged, just plug in the AC adapter.
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!

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).

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.
