>You can "increase" your battery capacity by ordering a $9,000 software update. Thats only for certain specific model and delivery time combinations. i.e just before they introduced the 90kWh option in production, some 85kWh cars were shipping with the 90kWh pack. If you ordered a particular pack before the next step size started shipping, then that's all you got. >Tesla batteries only show very little degradation because their capacity is limited by software Not true. It's mostly to do with active management of the battery, and keeping it within the optimal conditions for much of it's life. These are things your phone and laptop can't (or rather: don't) do. Everyone tends to plug in their laptop/phone and charge to 100%, then leave it there for long periods of time. Plus, laptops and phones tend to get very hot, and there's no active cooling of the battery. This combination of conditions tends to reduce the life of batteries significantly.

    Leaving lithium batteries at their extremes of charge state reduces their lifetime. Tesla recommends that their customers to charge to only about 80% for normal daily driving, and that if they need the full 100% range that they should start driving very soon after it reaches 100% charge. They also recommend not leaving it at empty for very long too as empty cells are more likely to drop below their minimum voltage, and die.
