Hello, I just bought this new laptop and foolishly didn't checked the battery life, which only amount to a mere 3-4 hours for typical use. So, I'm wondering if there is a way for me to upgrade the battery or replacing it with a better one (if needed). I love this laptop, but the battery is a bit too bad.
I understand you have battery issues with your laptop.
Don't worry I'll try to help you out.
Did you make any software or hardware changes on your PC?
Battery cycle life is the total number of discharge-charge cycles (Figure 1) a battery yields before it can no longer hold a useful amount of charge. Estimating the cycle life of a rechargeable Li-Ion battery is difficult because cycle life is affected by the average operating temperature of the battery and its energy discharge rate.
Basically, higher temperatures and higher energy discharge rates decrease battery cycle life. The operating temperature of the battery depends on the air temperature as well as the heat generated by the notebook itself and by its immediate environment, such as a docking station. The energy discharge (drainage) rate depends on the type of applications running on the notebook and by its power management settings.
For example, running computer-intensive applications such as CAD, gaming, and DVD movies drains the battery faster and decreases its cycle life more than running word processing applications.
A cycle for a rechargeable lithium-ion battery is the cumulative amount of discharge approximately equal to its full charge capacity. For example, 10 occurrences of a 10% depth of discharge or 2 occurrences of a 50% depth of discharge represent one cycle.

Also, try the steps recommended below.
If the original battery charges too slowly, but a replacement battery charges as it should, the battery might not be at fault. Before replacing the battery that appears to be defective or worn out, use the following instructions to determine if the battery needs to be replaced.
Search for and open Device Manager.
Click next to Batteries to expand the battery options.
With the options expanded, right-click each ACPI option and in the menu, click Uninstall.
Restart the computer.
