My Renault Zoe needs a new secondary battery - is this normal?

At my 4 year service on a Renault Zoe, I was advised to replace a secondary battery, not the one which drives the engine. The staff could not explain why this was necessary.

Can you advise please?

While electric cars have large drive batteries that power the electric motors, just like conventional cars they also have a regular 12V battery that powers the ancillaries such as heating, audio and so on.

Assuming this is the battery that requires replacing, it is not unusual for these to require replacing over time, although we would expect someone at the dealership to be able to explain why it required replacement.
