Hi, Does anyone know how much it would cost to replace the main battery on an MG car, if it gets damaged, for example, a 2020 ZS ev

The original post is nevertheless very specific about damage and this can theoretically occur within warranty as a result of hardware (or perhaps even software) failure.

I could theoretically drive 600 miles without stopping.

And the original poster in their subsequent comment was querying outside of warranty.

With a similar likelihood to a petrol engine blowing a major gasket, seal, or piston, and with a similar cost associated therewith.

You are all missing the point.
The OP didn't ask about age related degradation, he cited battery damage.

yes but afterwards went on questioning 10 year battery state and incentive to drive EV; bit confusing but either way - not worth changing the battery unless covered by warranty or insurance. New one too expensive, second hand ... - no thanks, not keen on roasting myself due to a dodgy battery someone recovered from a submerged MG ...

Hi I was just thinking that if the car was say 10 years old and out of warrantee i think the battery would cost more than the cars worth, so where's the incentive to buy an eclectic car

Unless we are talking widespread damage by water or something, it's unlikely the pack is a write off. 3rd party repair to replace affected cells, at a fraction of the cost, rather than replacing the whole battery, will become much more common place - as it is in countries like Norway with widespread take up.

Replacing an entire battery due to damage, or degradation of a one or a few cells, will be akin to replacing an entire engine because a spark plug is damaged.

If we are talking water damage or fire damage, why not ask the same question of an engine replacement in a car such as a BMW 3 series? You'll often find cars written off in that scenario.
