The lead-acid battery in my car holds 660Wh (12V, 55Ah) and costs less than $100. That puts lead acid at a quarter the price of the Tesla powerwall (admittedly without an inverter).

If you tried to use it like a PowerWall it would fail before it had reached 1/4 of the PowerWall's rated cycle life. Lead-acid is not a good chemistry for grid tied storage.
