What is the best way to maintain the electric battery in an Audi A2?

I recently purchased an Audi A2 and I am unsure how to properly care for the electric battery. Can someone provide some guidance on the best practices for maintaining the battery?

To maintain the electric battery in your Audi A2, make sure to regularly check the fluid levels and clean any corrosion on the terminals. It's also important to avoid overcharging the battery and to replace it when it starts losing its ability to hold a charge.
