Extended Capacity N856P New Laptop Battery for Dell Studio 17 1745 1747 1749 Series, P/N: U164P M905P U150P 312-0196 [11.1V 85Wh]

I bought this battery about one month ago and use my laptop one per week at the most. The first charge was amazing! Lasted a few hours. After the initial use, I am now lucky if I get 40 minutes before I have to charge again. I also get misleading and conflicting battery stats as far as time remaining and battery percentage. Odd. I do not recommend and must hunt for a better option. I am disappointed because this one seemed most reliable after hours of research one month ago.Update: Although it took a few months to receive, the seller reached out to me and sent a replacement battery. I am getting about 1.5 hours now and it has been almost one month of use. I appreciate the customer service and better battery. Hope this replacement lasts at least one year. For the cost, one year is decent in my opinion. If you are not happy with your purchase, reach out to the seller for a replacement.

I ordered this as a replacement battery for a Dell Studio 17/1749, and it fit perfectly, and performed as described. I especially like the fact that it has a built-in “stand”, which elevates the back by nearly 3/4”, which while it may not sound like much, does provide a noticeable-enough difference to make typing on the keyboard a bit easier when you have your laptop sitting on a flat surface. I will say that the stand may not be the best feature to have if you’re accustomed to actually using your laptop on your lap, as opposed to on a desk/table etc., because it probably wouldn’t be very comfortable against your legs when combined with the weight of your laptop. Overall, a good buy though...

I bought this back in December 2017 after a failed purchase from another seller. I am only writing this product review due to I almost bought another one from this same company. The battery from the start would only hold a charge for 3 hours, but I thought that I would chalk it up to guess they are all like this. The battery now after being fully charged only lasts about an hour, if that. The delivery and sellers were prompt so nothing bad to say about them, just a bad purchase.

Not as good as last replacement I purchased. Decent price. Time will tell on longevity.Skyvast contacted me and asked what could they do to help me on my battery issue and they sent me a brand new battery !Now that is customer service ! Thanks Skyvast !

this is a great battery , it not only has a lot of capacity but it holds the computor up and allows air to circulate under it for cooling. Much better than original

Having a battery that actually charges all the way up is great. This battery has been a life saver!

Replacement battery for Dell Studio 1747 laptop. Works great.

Put this battery in a Dell Studio 17 laptop and it worked perfectly. Battery life with normal use is approx 3 hours but a little less with more intensive use such as playing games. Would definately recommend as a replacement battery.
