As described there, this assumes slow overnight charging, and latest generation of batteries (not sure how viable that was the time of EV1).

Even LiOn batteries have charging patterns as the blocker to adoption, which means that practically, you'd get cars with less than 50% capacity by 2 years.

I mean 3-5 years doesn't sound that great to me since I've kept every car longer then that.

However, it's not like the lead went anywhere so recycling your batteries for new ones every 5 years could be very practical.

Also, not like it just keels over and dies, that's just the 80% performance criteria. Most people wouldn't need to replace the batteries at that point.
