Replacement batteries for a Prius were selling for $900 installed at independent shops in the Boston area last year. The $5000 figure is a) a myth and b) ten or fifteen years out of date.
$300 is obviously a projection but at the rate battery capacity is increasing will be true in a year or two. We're talking hybrid battery, not EV. Maybe something in the range of 1amp/hr capacity. Enough to recycle the energy from braking or coasting down a hill.
The Prius battery is small and the quoted price is after the core charge payment of the old battery. Not to mention the company subsidizing the "new" battery cost for public relations reasons.
