When you buy a dell you are stuck with their battery too. At first the battery seemed to work okay. In less than a year it does not hold power for longer than 45 minutes with light use. Dell will give you a replacement that carries you for a period that extends beyond the warranty period(if under 1 year from purchase). Basically, expect to pay $100+ every year.
I love my xps laptop, but i can't believe that such a high-end laptop would come with such a low end battery.
I had an inspiron before and the battery kept it's normal life-span for the 3 years I used it.
This time with the xps, it has been only over a year, and the battery won't last for more than 30 minutes. It can't be because of my usage, since 80 % of the time I have it plugged in.
Life is too short...especially for this battery!!!
I ordered the 6-Cell Lithium-Ion Battery from Dell. The battery was was delivered even earlier than expected. I was glad it did cause I was about to travel. This battery is however a replacement for the one that came with my laptop and so far its working great. On full charge I get close to 4 hrs, which works fine for me.
I bought this smaller battery after getting the 9 cell battery with the original purchase. The combination provides over 9 hours of run time, but this smaller battery is good for about 4 hours with a full charge in place.
The battery woks fine. Does not hold charge for any longer than and factory battery. The main reason I am giving this product a bad rating is because when I purchased my laptop I expected it to come with a battery, which it did. I was forced to buy an extra one. When I purshased my laptop (online from dell.ca) there was NO option to NOT choose a battery so I chose the cheapest one! Now I have 2 battery and only 1 laptop that it fits in! Waste of money!
This battery came with the XPS 17 for free as part of a promo deal at the time which was great! The battery lasts about 3 hours playing multimedia (Almost 4 on low performance word processing) and is a great option for back-up power at the end of the day. The ability to check the charge of the battery with a press of a button without having to power on your laptop is quite the bonus. However, the battery was on call-back and I waited about a month before receiving the battery. That's quite a long wait, but Dell kept a follow-up on the order and assured me that it was going to come eventually over the month. The battery also sits flush with the back of the laptop which makes it easier to transport as opposed to the over-sized battery that comes with the XPS 17; although this puts a bit of strain of my cooling mat as there is less space for the air to flow (taken into account that the XPS 17 lacks enough intake vents on the bottom of the laptop). Also, I haven't got any numbers but it seems to charge slower than my over-sized battery which was surprising!
Pros:powering my l702x (xps 17), back-up power option
Ok, overall.. the battery gets a 6.5 out of 10 reasoning.... very sleek,, fits nicely into XPS 1502..BUT.... Run time: varies.. usally no MORE than 2hrs 15 min.. apps running.. Media Palyer.. and a "scrabble game" it would be nice if it had an longer runtime
If the 9 Cell was more afordable, im pretty sure i would purchase it..
Bought my XPS 15 with the 9-cell battery, got this one for times when the added bulge of that one would be a pain. I get 3.5 - 4 hrs on this 6-cell. It works and it works pretty well.
I rated it 3 stars because although it is labelled a 56Wh, the Dell Support Center software indicates it's only 52Wh. If you multiply the labelled nominal voltage by the rated Ah (11.1 x 4.84) you get 53.7Wh...so no matter how you slice it, it's not really 56Wh. Oh, I called tech support and the only answer they could give me is that no matter what the labels and software say, it's 56Wh - but they couldn't offer any proof or explanation of any sort.
I bought my XPS14 with the extended (9-cell) battery, which has a hump sticking out of the bottom for the extra 3 cells. This is the "standard" battery you'd get with the XPS14 (and some other Dell laptops) and is totally flat & flush with the rest of the laptop body.
Performance varies based on what you're doing (anything CPU intensive will run down the battery much faster than say, reading a PDF). Playing a movie gets me about 2 hours, while the extended battery gets closer to 3 hours.
