Will the battery in my hybrid keep going?

With gas prices still relatively high, more and more people are considering hybrid cars. But some readers are wondering how long the batteries in a hybrid vehicle will last.

…The battery pack in a hybrid vehicle contains hundreds of cells. Unlike the lead-acid battery under the hood of a conventional gas-powered vehicle, these cells contain a chemical mixture called nickel metal hydride (NiMH).

These NiMH batteries generally come with a standard warranty of 8 years or 80,000 miles. In California and several other states, the warranty is required to be 10 years or 100,000 miles. From all indications so far, these batteries have been very reliable.
