the life of the original battery is about one year, for the original battery,if you use in the right way,one years later,the full charge battery can be used about 2 hours;but if you use random,it can not,so as myself,i buy one more chargers,and put them in the place where i use them beside my car.. Cheers.

Full Answer. Without a battery, the laptop will not work on its own. It must be connected to a wall outlet in order for it to work. If the charger disconnects, the laptop will shut off. Laptop owners should not keep their laptop on the charger at all times. The battery needs to naturally drain before being recharged, and this is the only way to keep the battery working for a long time. However, power users should consider replacing their batteries once every 12 to 18 months.

For example, if you draw 1 mA for 1 hour from a battery, you have used 1 mA · 1 h = 1 mAh of charge. If you draw 2 mA for 5 hours, you have used 2 mA · 5 h = 10 mAh. You can approximate how long a battery will last by dividing its total charge (in mAh) by your nominal load current (in mA). Say you have a 1800 mAh battery, and you connect it to a 20 mA load:

The mAh of a battery, IS a general indicator of how long a battery will last. a 3000 mAh battery will last 3 times more that a 1000 mAh battery (in the same circuit/application).

Protect the screen and body of your laptop. Your laptop will last much longer if it doesn't get damaged. Don't attempt to twist the screen on its hinges, as this could crack the screen. Do NOT attempt to close the lid when a pencil or pen is left on the keyboard. This could crack the screen.

The recommended charging time should not exceed 1 hour. Typically, this should charge the battery to between 80% and 100%. (Some discharge will take place over time. Stored batteries are expected to discharge 10-15% over a four month period, for your information.)

So the amount of charge you're supplying and the amount the battery will absorb are in the same ball park. In the middle, the silver NiMH battery recommends a charge of 200mA (milliamps) for 7 hours, which gives us a charge of about 1400mAh. Again, the battery itself claims its capacity is lower than this (1000mAH). At the bottom, the green and orange NiMH battery recommends a charge of 63mA (milliamps) for 18 hours, which gives just over 1000mAh. The battery is rated slightly lower (970mAH).

Battery Life on mine. my battery life is about 2 hours on a Compaq Presario F769WM with 2 Gb of RAM and a 150 Gb Hard drive. I did have an Acer 3502 WLCi that only had about a 30 minute battery life and it was only running 512 Mb of RAM and a 60 Gb hard drive.

Caring for laptop parts. 1  1. Make sure your electrical cord helps your laptop, and doesn't hurt it. Treat your laptop's electrical cord as an extension of the laptop itself. 2  2. Remove disks with care. Small pieces are easy to snap off if you are not careful. 3  3. Extend the life of your battery.
