The BMW 318i is an older 3-series (E30 or E36 in the US), and it uses a conventional 12V flooded lead-acid battery, roughly 60 to 90 Ah depending on the application, to start the engine and run the electronics. This is a used battery, load tested before it ships, with a typical service life of about 4 to 6 years depending on use and climate.
Two notes from cleaning up the live page. First, the live copy went back and forth between lead-acid and AGM; for this older 318i the correct battery is flooded lead-acid, so that is what we describe. Second, unlike the newer X1 and X5, the 318i predates BMW's battery-registration system, so you do not need to register a replacement to the car. Confirm your group size and CCA by VIN.
