A Guide to Selecting Dell XPS Laptop Batteries

The Dell laptop battery you choose for your XPS will affect factors such as weight and how long the battery will last. Having the right amount of charge when you need it can aid in productivity as well as mobility. The type of Dell laptop battery pack you choose can also influence how often the pack needs to be replaced.

Over time, rechargeable notebook batteries wear out. It takes approximately 18 to 24 months before a reduction in operating time is noticed. For someone who frequently operates a Dell XPS on battery power, this reduction might be noticed earlier than 18 months. Its ideal to replace the pack when you notice the performance isnt meeting your needs.

Higher watt-hours will give you longer battery life than one with lower watt-hours. For example, a 53 watt-hours unit, when compared to a 32 watt-hours unit under identical usage conditions, is going to give you approximately 60% more operating time on a single charge. Choosing a unit with higher watt-hours than the original isnt going to damage your XPS, so its a viable option if you will be using the XPS on cell power for hours at a time.

When choosing the right battery for your XPS, think about how you will use your laptop. If weight is a primary concern, youll want to opt for a lower watt-hour battery. If you need to use your laptop for long periods of time on battery power or use multiple programs or run software that is graphics heavy, youll want to select a higher watt-hour battery.

Replacement is very easy when you follow a few simple steps:

1. Turn the computer off.
2. Disconnect the AC Adapter cord.
3. Close the Dell laptop.
4. Find release latch on bottom of computer.
5. Trigger the release latch and remove the old battery.
6. Place the new pack into the designated space.

Dell batteries have LED gauges on the bottoms of the batteries. Simply push the button and the LED lights will reveal how much charge is left. If the unit has been charging for a while and the LED lights never show a full charge, this is a sign that the overall battery life is declining.
