Charged the new battery overnight, about 13 hours, after I installed it, turn my Bose speaker on, played for about 15 hours non stop, until red light (low battery) came on. Seems to be a good battery!!! Pleased with performance of it. It was easy to remove the old and install the new one, takes about 5 minutes.

This battery was a perfect match for my Dell Latitude laptop. Super easy to install, works great, fast shipping and great price!

Worked perfectly! Easy to install.

The item was delivered on time and in good condition. Fit perfectly in my Soundlink III speaker and seems to hold a charge. I have only had it a couple of weeks so I can’t say anything about it’s longevity.

My battery on my computer was dying and could not go above 98%, with this one I finally got to 100%.

Currently, I gave the product a max review. I've only had to use the battery a handful of times thus far, but from what I've gathered it is working just fine. The packaging the device came in was well prepared and protected. They even included a small screw driver and separator tool, which I thought was incredibly thoughtful of the company that sold it. On a side note, I would consider it 'Easy to Install', but I work in IT and I've installed quite a few batteries in laptops, macbooks, etc... The particular model I replaced the battery in, requires about 9 screws (Note: The screws are different sizes, so you will want to record the placement of the screws in some manner so you can put them back into the propre places) to be removed from the bottom of the laptop, then you use the separator tool to 'unsnap' the top plate with holds the keyboard, and mouse touchpad. After the top plate is loose, you need to raise it enough to get visual on 3 cables, disconnect the power button cable, the mouse touch pad cable, and the keyboard cable. From there, the battery just comes right out, it has a connector on the left-hand side, and only fits in one way. I also swapped out the mechanical hard disk drive for a SSD while I had it open. All that said, it is really only something I would suggest to someone comfortable with doing so, easy for some, perhaps a bit intimidating for others, never attempt something you are not comfortable doing.

Two batteries, both bad. 1st battery would not charge past 70%. I returned it and got a replacement. The replacement was completely failed. I attempted to contact the seller via the support link. The web site does not exist. I tried to call the seller on the listed number. It was always busy.

Works great! Wish it came with a tiny torx screwdriver.
