Not sure what Dell was up to here. My last Dell lasted quite a bit and hence gave another shot with Dell with XPS. Within 18 months the battery was at about 2 hours and after that the battery error started showing up and battery lasts at most 1 hour. I have lost faith in Dell and it's capability to produce great products.
After looking over several configurations of new Dell laptops (new 7000 series), I compared what was available vs. my 2012 XPS15 and decided to upgrade my current laptop . . and purchase a new battery as well while they are still available. I decided on the full 9 cell battery with the 'raised' section to get the most for my $$'s. After several weeks of cycling through the full charging/discharging of the new battery I am happy with the 6 hrs or so performance. This is a back-up to the battery I have from the original laptop purchase which still works fine (I don't use the laptop as much as most individuals I am sure).
The battery is easy to install and offers up to 6 hours of battery life. I don't have to carry my charger anymore to school. Also I don't have to worry about being around a power outlet to charge everywhere I go due to the longer battery life. The battery adds a little bulk to my computer but it is better than dealing with a charger.
My less than 3 year old Dell XPS (my third XPS and the last Dell I'll ever buy) battery died completely. It started being a problem just after the warranty expired (go figure). I never was really able to use it unplugged. Hopefully this battery will hold up (the replacement on my previous XPS never really performed as it should). In any event, after buying Dells for more years than I can remember, I finally really mean it when I say NEVER AGAIN.
I had to replace the original 90 WHr 9-cell Lithium Ion battery on my XPS laptop, which is three years old. Had heard some horror stories about after market products, therefore decided to purchase Dell replacement. Very happy and satisfied with my purchase.
Had an older 60whr battery, despite that this battery is only 30whr more it lasts more than twice the battery life of the old one. I am sure part of that is due to the lithium battery being used up some and not storing as much charge as when it was new, but regardless it the battery lasts 4-6 hours depending on what I am doing, and I am very pleased with the purchase.
I bought my computer January 2012 and the battery lasted a year. Now it only charges to 61%. For the money, that's unacceptable. I would have saved money buying generic batteries and just replacing them every year. Never again.
This has been the worst computer I've ever bought (xps 702x). No wonder Dell stopped making them.
My original battery died after a 1 1/2 so I bought a battery from a aftermarket supplier and it died in 3 month's so they pro rated the battery and I got some money back. I bought this battery from dell with a one year warranty. I asked a dell rep why the original only lasted 1 1/2 and they said it was because I use the computer so much. I guess my point is that the computer is large and has the best processor on the market at the time I made the purchase so the battery life is going to be poor. Buy Dell for the extra cost it's worth it.
I've only had my XPS L702x for about a year and a half and I'm already receiving the "battery has experienced a permanent failure" message. This upsets me because I have a 5 year old Dell Vostro 1500 with the original extended battery still holding strong. On top of this failure, Dell now wants $156 for a replacement.
I got the 9 cell battery when I bought my laptop a year and a half ago and it was fantastic! It could hold a charge for numerous hours, while doing energy draining activities.
However, about 3 weeks ago I woke up, turned on the laptop and suddenly the battery would not charge beyond 60%. Over the next 3 weeks that max charge limit slowly dropped to 52%. Fast forward to 10 minutes ago, I was in the middle of a movie and suddenly the laptop turns off. When I plug it back in, an error message came up saying "Your battery has experienced a permanent failure and needs to be replaced". I was doing absolutely nothing, and somehow in the course of a month, the battery just died on me. Dell's customer support was absolutely no help and they kept telling me that they could do nothing for me, except charge me another $156 for a new battery.
Complete trash, and it makes me think that this battery had built in obsolescence. Only worth your time if you're willing to shell out an extra $150 every year or two, to have the extra battery size/longevity.
Awesome product when I received it. Lifts the back bottom side of the laptop up and a little space for air circulation. Pros: Much better than the 60. Long Battery Life. Cons: Cost. Dell Agents couldn't give me a discount on this because it was replacement, spare parts.
The only "con" I have is the cost. My old battery was starting to fail, so I needed a new one. But...the replacement is so darn expensive. I'm beginning to think that these are being viewed as "consumables" like printer toner cartridges. Unfortunate if true.
I recently purchased a replacement batter for my laptop (90 WHr 9-Cell Lithium-Ion Battery for Dell XPS 14 (L401X)/ 15 (L501X)/ 15 (L502x)/ 17 (L701X)/ L702X Laptops). I chose the slightly more expensive battery that has a longer life. I have had the laptop unplugged while using it for 3 hours at a time and haven't run out of battery life -- which is a welcome change! I recommend paying a little extra for the longer life. Nothing more annoying than running out of battery power and having to go back and plug in when you're in the middle of a project.
Great to have an extra battery for travelling especially but the weight to carry around is so heavy in my bag...shame battery design can't be smaller nowdays! Cost is way over what I expected, but no choice I need it! Terrific shipping time thanks Dell!
