I got a brand new replacement battery for my alienware laptop, it lasts an hour when gaming which is fine, problem is that after 30 minutes the battery drops down to 0% critical level and then it stays there for another 30 minutes before shutting down, normally the laptop would sleep at 5% but i disabled this to test.

Done at least three full discharge and recharge cycles, battery health has also dropped to 91% already which seems crazy, is this just either a faulty battery or perhaps because it is non genuine?

My original battery was 44T2R (68wh) and new is 9NJM1 (99wh).

I purchased from - https://www.delllaptopbattery.co.uk/dell-alienware-15-r4-batteries.htm

That is the problem with non oem equipment. Repair shops buy them to reduce final cost to the consumer. It may have sat on a shelf for a few years. Batteries always degrade over time. You don't mention whether you installed it yourself, but I would make an effort to return it. Clearly it is out of spec.
