Why My Asus G73jh The Battery Works For One Hour Only?

Because you did not properly protect your laptop battery, I'll teach you some of the ways:

1. New batteries must be fully charged before use

To put your laptop battery in optimum condition for long-term usage, please fully charge the battery before its first use. Very importantly as well, for the first 3 charge cycles, always fully charge before use and fully discharge before recharging.

2. Calibrate the laptop battery
every few months

Almost all notebook batteries are created with an internal microprocessor, which provides an estimate of battery conditions such as number of charges, discharges, full charge capacity and cycle charge count. The full charge capacity will become a little inaccurate after a few months and calibrating it can help restore the battery’s performance.

 

3. Use your battery in the proper conditions

Generally speaking, batteries work best at around 68°F (20°C), but temperatures between 32° to 95°F (0° to 35°C) will allow a laptop battery
to works in good condition too. Allowing your battery to work in conditions that are too hot or cold can lower its performance. It may also have a negative influence on the battery’s lifespan as well.

4. Store your battery in the proper conditions when not in use

If you don’t plan to use your notebook for a month or more, we recommend the laptop battery
be stored separately in a clean, dry and cool place. Please also ensure that the battery has about a 70% charge remaining. During storage the battery will perform a slow self-discharge, so we do not recommend storing it for a very long time (3 months or more), because it can impact the wellbeing of the battery.
