Cannot Recommend
This battery looks identical to the original manufacturer battery, but the fit is not perfect on one end (see photo). While it is supposed to be compatible with the model of my laptop, when the system starts I always get a warning stating that the battery is not recommended for my system and will not be able to be charged. The battery DOES charge, however, and the charge lasts for 3-4 hours; not quite as long as I would expect for a brand new battery. I will keep it, rather than go through the return hassle, but I'm dissatisfied. It is very annoying to have to click through the "not recommended" warning whenever the laptop restarts from sleep.

Best
This was one of the best services I have ever received. I really loved the battery unfortunately my computer couldn’t accept the battery. However, the seller tried all their best to help me get the battery working, unfortunately it couldn’t work out. I got a refund from the seller. I am still looking forward doing business with this seller. You will have no regrets doing best with them.
