Not really. On a battery unit, the time and number of charge/discharge cycles [wear] can be measured and used to calculate the depreciation of the battery during the time it spent in any particular car. The user can then be billed on a swap.

The benefits to this are that the cost of the battery is spread out over time for the customer. And since the customer is always effectively paying the difference in cost of the deposit on the battery, the battery in their car will never exceed the value of what they have paid already. This also makes it way easier to recycle batteries once they have reached end of life as well.
