Battery question

[oldwheels]

I have bought a used trike with Shimano Steps and an E6000 battery. I would like to get another battery but am bamboozled by anything I can find online.
Can any other batteries fit?
I would like perhaps an E6010 for example but cannot get any sensible answers anywhere.
Anybody got experience of using different numbered batteries?

Thanks for that. It tells me more than I had before as the trike is pre 2019 and so only a E6000 will fit I think.
