In Dell website the Dell 9 Cell extend Dell Inspiron 1520 battery can last 7 hours (so long time). But in our daily use the battery only can run 5-6 hours. Where did the rest 1 hours go? In fact the 7 hours is the standard time that the battery run in the strict situation.
Below the battery4.us list the strict situation for you to get back the lost 1 hours. To increase the Vostro 1510 battery discharge time (maximum running time), try the following tips:

3. Reduce the screen brightness as much as you can.
4. Switch off the wireless card whenever you are not using it that can save Dell inspiron 6000 battery power.
5. Disconnect any peripherals eg if you use a USB flash memory stick, copy any files you need and then unplug it. This can give an extra 20 minutes or so of use.

7. Change the Control Panel - Alarm settings to their absolute minimum (eg 4%). This can gain an extra ten minutes of use (but the notebook may cut out suddenly if you have a degraded Dell Latitude D830 battery).
