Nope, the typical £10k to £12k on cars costing £30k, something like a Zoe for example, a Tesla Model S is around £20k to £30k depending on size with the Tesla being £60k to £100k to buy new.

The old battery is still worth a significant chunk of change as well, they certainly do not need to go in the bin. We haven't even started refurbishing old batteries yet, just repurposing them.

Couple that with more modern batteries often being bigger capacity for same sized packaging. Model S 60kwh with 70% usable is approx. 42kwh usable. Upgrade that to 85kwh and you've doubled your usable battery, so better than new.

Oh, and you'll often get another 7 to 10 year guarantee on the battery as well.

So nothing like a phone battery, well maybe one from Apple replaced by apple with an actual enforable warranty
