Highly doubtful you still looking for a battery 2 years later but I post my advice here for future fixers lol.

Sadly dell no longer sell the official battery, I recommend trying Amazon and if it doesn't work return it for a refund and try again.

Amazon has the best refund/return policy.

Don't trust eBay I had multiple batteries expand within minutes after powering on and I was left in the dust with no refund.
