Hi sulaiman khan,
There are several things you can do to make your battery last longer:
Choose the right battery. Under the same use conditions, a lower capacity battery will wear out faster than a higher capacity battery because it has to be charged more often.
Use the notebook's power saving controls to reduce battery use in your normal day. For example, turn the Bluetooth off if it is not needed; reduce the screen brightness when conditions permit.
Avoid exposure to extreme temperatures. If the system is exposed to extreme cold or hot temperatures, allow it to warm up/cool down before use and before charging.
Contrary to last decades' batteries, modern lithium ion batteries do not need to be fully discharged to maintain health.
All batteries wear with use and time. When you find the runtime is no longer satisfactory, it may be time to purchase a new Dell battery.
The battery charges in the laptop when the laptop is connected to an AC power source via the AC adapter. The charge time varies depending on the system. If the system supports ExpressCharge. The battery typically will have greater than 80% charge after about an hour of charging, and fully charge in about 2 hours with the system off.
Once the battery is fully charged, ensure to stop charging the battery.
All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new Dell laptop battery when the run time does not meet your needs.
Batteries tend to deteriorate over time. Keeping battery in the laptop and plugged to the power outlet at all times would actually causes damage to the battery and causes it to be more energy inefficient, not storing energy.

The above is mostly correct. However, keeping the battery in the laptop does NOT affect it's lifetime. The battery circuity stops charging when the battery is fully charged. If you take the battery out, why have a portable computer? The only time a battery gets much above room temperature is during recharge. I have actually monitored battery temps and find they run usually only several drgrees warmer than the ambient air temperature.
In addition to portability, the battery is also a power backup if you have an eelctric power failure. I have a five year old M1530 and still using the original battery. The initial battery capacity was 85% of theory, and today it is 50%.
Battery life depends on many things. Important are the number of discharge/charge cycles and how low the charge is allowed to go. In normal operation, I recommend to not go below 35% of the full charge too often before recharging. In order to get a long battery life, electric car manufacturers set the maximum discharge level to 35-50%. These batteries are warrantied for 100,000 miles.
