HP Long Life Notebook Battery (HP MU09)
on June 9, 2014
I ordered this HP MU09 from this seller because they posted the OEM picture of the original product with the battery meter on the side. (The meter is the four little lights on the bumpy side of the battery with a push button which allows the user to check if the battery is still good or need to be replaced.) When the push button is pressed, all four lights should turn green for a battery to be considered new. This fact does not for certain guaranty that when your Laptop is running on the full charge, you will get the 6 to 8 hours run without wall power because batteries loses capacity for being stored for a long time.
After receiving my battery from this seller (WICOO E-Mall) i noticed that the battery was different from what they have posted on Amazon for sale. The battery looks similar to the OEM posted but doesn't have the four lights with the push button to check the capacity. After inserting the battery on my laptop ( HP DV 7 Quad edition) there was a little gap on the side where the pins are located letting me believed that the lip was little short. Knowing all this facts, i wanted to keep the battery. I gave a full charge and checked the battery sign on my task bar which shows the user how long one can run their laptop without refueling. To my surprise, a full charge on the battery they sent me was 2 hours and 13 mns power life. A new and fresh battery of this kind last about 5 to 8 hours on the single charge.
When i contacted "WICOO E-Mall" to address my concerns with a replacement, someone responded to my inquiry by saying this, " hello, if you do not need the battery, pls kindly return it to the following address:....when you posted it, pls give us the tracking no. of the parcel and when we have received the parcel, we will refund the payment to you..."
Here is the bad news; you would have to pay for the return shipping fees. I will not recommend buying from “WiCOO E-Mall” because they are selling Chinese copy of the HP MU09 Long Life Batteries unless you had a pleasant experience with them. The battery i received cannot be covered by any warranty from HP because this product is not genuine HP Long Life Notebook Battery MU09.
