Latitude E5570 - Replacement Battery

Hi,

I need some advice re: replacing the original battery in an 8 year old Latitude E5570 laptop.

The specs on Dell support for my service tag says:

but when I'm searching for a replacement I'm presented with such a plethora of different choices I'm totally confused. And I'd rather not spend $80 for a "genuine" Dell battery on an 8 year old laptop.

Can someone please recommend a compatible battery for the E5570?

Please and thank you.
