Working Ok so far
By Gary Jones on August 10, 2013
Verified Purchase
I bought this to replace a 3 year old Dell Studio 1558 battery that was getting weak. It wouldn't last an hour. This replacement was not too expensive and there were more positive comments than negative so I thought I would give it a try. It fit just as well as the original. I would consider it a perfect fit and it looks pretty much identical. I've only charged it once and I got maybe two hours out of the first charge. We'll see how well it does after a few full charge cycles. One odd thing did happen. After applying a windows update (Office 2010 patch IIRC) and rebooting, I did get a BIOS error that says it was an unknown battery and that charging was disabled (or something to that effect). After I rebooted to clear the message, it charged just fine. That only happened one time and it's working well now.

So Far, So Good.....
By K. Spahr on August 16, 2013
Verified Purchase
This battery arrived at my door a little over 24 hours after I ordered it....simply amazing how fast they packaged it up and got it to me. It came with very detailed instructions on how to charge it up properly as well as a battery basics tutorial....very nice. I would not have known how to go about charging and discharging it to get it to full capacity without the included flyer. So, I did the charge-discharge cycle at least three times and so far, everything seems to be going good. The battery fits perfectly, it was packaged superbly with double padding inside a padded sleeve inside a shipping envelope. Very nice. With the warranty and the price compared to a Dell battery, this could prove to be a very nice deal...if it lasts. Believe me, if this battery goes south too soon and the warranty proves worthless, I WILL be the first person on here b*tching about the situation! But as of now, I'm one happy camper!

High Performance? What a Joke.
By K. Young on January 5, 2014
Verified Purchase
I wish I could do lower than a 1 star on this battery. I replaced my old Dell battery about a month ago with this battery. It totally stopped charging a couple of days ago. I thought at least it has an 18 month warranty. Well I am supposed to pay to send it back (this company should back up their product with call tags) and pay the shipping on a new battery. To do that I was supposed to call an 800 number and pay with a credit card. When I called I was told I was first in line for customer service and then promptly sent to a message machine. No one called me back. Bad product, bad customer service. I will never use this company again. Not sure why it is an Amazon Prime affiliate.

Exact fit, worked right out of the box.
By M. Moore on February 17, 2014

First order got fouled up somehow, but once re-ordered, came quickly and works very well. This looks exactly like the OE one that I replaced.

Good battery, Great price!
By Daniel P. Huser on February 16, 2014
Verified Purchase
So far, So good. After conditioning the battery with 10 charge/discharge cycles, I am getting about 4 hours of operation on a charge. Now if it lasts as long as the original, it will be perfect.

Just fine

Fit in my laptop, did what I needed it to do. My computer randomly shuts down but I'm fairly certain it's a computer issue, not a battery one.
