Absolute rubbish, where's your link to ev batteries continually being replaced? They will lose capacity over time depending how it's treated, but those losses won't make the battery non usable, it will just limit the range. Leaf offers a 8 year /100,000klm warranty on the battery to maintain at least 70% of it's capacity. Tesla offers 80% capacity. If batteries were being replaced in ev's like you claim then it would be common knowledge. If your link is from a Mobil website don't bother posting it. The graph below, which is NOT from Tesla, it's from a group of Tesla owners and charging networks, shows historical depreciation of Tesla batteries compared with number of recharges. If you can understand the graph it shows that after 500 charges the battery capacity is still greater than 90%. With close to Zero maintenance other than tyres and a good buff.
