>It's not as if the batteries people are paying for become their property
It is as if. The article says it's a lease agreement, and provides this link.

It's a 10 year lease agreement. You pay them, and when the 10 years is up you have to return the batteries. At no point does the customer own the batteries.
It's like leasing a car, except with a car lease you have the option to pay extra to buy it out at the end and take ownership; with this lease agreement you don't.
