You don't understand how the battery in a hybrid car works.
They last VERY long because they are NOT deep-discharged like your rechargeable batteries.
Rechargeable batteries wear out because of all the full-charge-then-full-... cycles. Hybrid car batteries DO NOT do that.
The Prius hybrid computer is always trying to keep the charge state of its hybrid battery between 60%-80%, where it has a life span measured in decades. Even when you see the charge state in the Prius MFD display a low charge state of just 2 red bars, the battery is still 60% charged.
Purely Battery-powered electric cars like the Tesla do go through full-charge-then-disch... cycles, which is why their battery life is problematic-- Tesla recommends replacing the battery pack in the Roadster after 5 years. Non-plug-in hybrids do not suffer from this problem because they don't deep-discharge their batteries.
