Same physical size and shape for either chemistry--your choice. Interchangeable.

20-yr sodium battery good for cars everywhere, especially in colder climates.

Lithium battery for warmer climates and higher power.

Car wears out before battery, especially given the 20-yr battery life. Replace car every 10-12 yrs, just transfer the existing battery from the old car.

Trucks and delivery vehicles will use sodium due to cost to buy AND operate.
