    As Dell no longer sells genuine batteries, I just bought a generic replacement battery for my M18xR2. I rang Dell Tech Support first to check that the battery i intended buying was suitable and they confirmed it was.
    My problem is the battery life. When new my original battery would last at least 4.5 hours on iGPU. This generic one barely lasts 2.5 hours on iGPU.
    Is this normal or do I have a faulty one?

    The OEM battery was a whopping 12 cell, very few generic batteries will actually give you a 12 cell battery. More likely you got a 6 cell

    Did you buy the battery from a seller listed in China? If so, you will get a low quality battery. Not much you can do other than look for someone in some other region (not China) that is selling a used or OEM battery.

    No the seller was in Australia (where I am). The battery is a 12 cell. I have batteryinfoview running it says Manufacturer is SIMPLO, Full Charged Capacity 97,650mWh. My tech mate took a look at it yesterday and he said the specs seem identical to the original (however I guess it wouldn't be hard to make fake labels and stick them on a battery) but the stats from batteryviewinfo suggest it is the same as the original.
    Maybe I just got a faulty one.

    That's the same as the one I bought, same part number but if you read the fine print at the bottom of description it says :
    Country of Manufacture: China
    Brand: For Dell Battery
    Compatible Product Line: For Dell Alienware M18x R1 R2
    Compatible Brand: For Dell
    Compatible Model: Alienware M18x,Alienware M18x R1,Alienware M18x

    I got a reply from the seller when I complained about the poor battery life

    Hi sorry to hear that ,

    most of our battery max are about 2-3 Hours.
    only the one with come from the laptop itself is 3-5 hours


    That speaks for itself. Cheap crap :(

    Weird, the one I got lasts fine. I get 3 1/2 hours with my usage. Old battery was around 3 hours. New battery is 5% wear, old one was like 15% wear. I mainly got it to hot swap and have 2x battery life.

    Maybe you got a good battery. Sounds like I picked a bad one. Time will tell I suppose as I rarely run my laptop on battery except during power outages. I have a choice to make, send it back for a refund and buy from a different vendor or keep it and grin and bear it. 2 weeks to make up my mind.
