Question: is this actual HP unit? I have HP pavilion DV6-2173, will this work?
Document: This is the second battery I bought based on the product description which is disingenuous. This battery is NOT compatible with HP Pavilion DV6. I was quite upset when I found this out and had to send it back in for a refund. Hopefully, no one else is duped by the product description like I was.
I own an HP Pavilion DV6. This battery advertises to be compatible with my laptop, so I purchased it. When I received it, I found it does not fit my laptop. It doesn't even line up the same as the battery currently in it. I would think the battery should be checked for compatibility prior to advertising it does. I'm sure if it were compatible...I would have had a five star rating!
I ordered this when my original 12 cell battery died after 4 years (HP Pavilion DV6-1247cl). This one definitely doesn't last as long as the 12 cell (usually about an hour on light usage) but I just needed a functional battery to keep my computer from dying when someone kicks the power cable out of the wall plug.

The battery works fine as long as you are using an actual HP power cord with it. When I first got this replacement battery it did not work with the cheap power cord I bought for $15 off here. If you need to replace your battery and/or power cord (as I had to after less than two years), this battery is fine but spend the extra money ($25 on Amazon) and buy the right HP power cord.
Ordered this product for my HP Pavilion DV6. The connectors are in the wrong position so it is not physically possible to use with this laptop.
Ordered this for my HP Pavilion DV6 as the original battery had lost its ability to hold charge. This new replacement battery fitted without any issues what so ever. Cheap price, does what it says on the tin and was delivered faster than expected, what more could you ask for... Well recommended!
Had to replace OEM HP battery in my in my DV4 and this battery fit the unit perfectly. It charged right up(I let it charge fully overnight before using it)and it seems to work fine. It is a good value, probably better super batteries out there, but this was affordable and works fine.

It did not work for my HP Pavilion DV5, I don't know what else to say. Not what it said it was
Answer: It is not an official HP battery, however... I bought this replacement battery about 6 months ago for my HP dv6 and it has no given me any problems at all. I am very pleased with the battery and well worth the price.
