Haters love to claim that the Tesla car batteries, the ones that power the car, will only last 2 years or less. Well, now we have some data coming from actual owners and their experiences.

Maarten Steinbuch blog about Tesla Model S battery degradation data - https://steinbuch.wordpress.com/2015/...
As the data shows owners are experiencing greater than 93% battery retention after 220,000 miles of driving. This is incredible as many owners aren't likely to drive their car this far nor retain the car for much after.
These data are encouraging that owners of used CPO Teslas, like myself, will have a great time ahead of ourselves without any worry about replacing the battery.

// Tesla Model S Batery (src: wikipedia.org)
In 2012, the EPA range for the 60 kWh battery pack model was 208 mi (335 km) and the 85 kWh battery was 265 miles (426 km). According to Musk, the Model S has a battery with twice the energy density of that on the Nissan Leaf, but the difference in range is more than double. This is also due to other factors such as drag coefficient, weight, motor efficiency and rolling resistance. Musk stated that driving at 65 mph (105 km/h), under normal conditions, gives a reasonable range of 250 miles (400 km).
The energy-saving sleep state powers off the display and other vehicle electronics, after the car goes to sleep. This increases the time it takes the touchscreen and instrument panel to become usable. This mode can decrease the loss of the car's range when not being used (2.3 mi, 3.7 km per day, as of 2013).
The 85 kWh battery pack weighs 1,200 lb (540 kg)[better source needed] and contains 7,104 lithium-ion battery cells in 16 modules wired in series (14 in the flat section and two stacked on the front). Each module contains 6 groups of 74 cells wired in parallel; the 6 groups are then wired in series within the module. As of June 2012, the battery pack used modified Panasonic cells with nickel-cobalt-aluminum cathodes. Each cell was of the 18650 form factor (i.e., an 18 mm diameter, 65 mm height cylinder), similar to the Panasonic NCR18650B cell that has an energy density of 265 Wh/kg. Analysts estimate battery cost to be around 21–22% of the car cost. List price for a replacement battery was US$44,000 in February 2015.
The battery is guaranteed for eight years or 125,000 miles (200,000 km in metric countries) for the base model with the 60 kWh battery pack. The 85 kWh battery pack is guaranteed for eight years and unlimited miles. A poll among drivers indicate that accumulated battery loss steadies around 5% after 30,000 miles (50,000 km), decreasing further about 1% per additional 30,000 miles. Unlike Nissan, Tesla does not specify a limit for battery loss, but some early battery packs have been replaced.
A separate battery replacement guarantee takes effect after the eighth year at a cost of US$10,000 for the 60 kWh battery and US$12,000 for the 85 kWh battery.
In 2013, Tesla canceled a 40 kWh version of the car due to lack of demand, stating that only 4% of pre-orders were for the 40 kWh battery option. Customers who ordered this option instead received the 60 kWh pack, with charge software-limited to 40 kWh (139 miles, 224 km). It has the improved acceleration and top speed of the bigger pack and can be upgraded to use the full 60 kWh for US$11,000.
On April 8, 2015, Tesla discontinued the Model S 60, and replaced the base model with the Model S 70.
In 2015, Tesla introduced a 70 kWh battery to replace the existing 60 kWh batteries and base 60 kWh Model S vehicles, as the 60 was low margin and not sufficiently welcomed by customers. All 70 kWh cars can be had with rear-wheel drive or all wheel drive. The 60 was re-introduced in 2016 as a software-limited 75, upgradable to 75.
