 @Greg -  I didn't know that the operating temperature affects the battery life. If so have the battery manufacturers looked at taking necessary steps to maintain the required temperature?

@Greg –yes as you said I wonder if these batteries will last that long. Is this just to make the sale or does the battery actually stay alive for this number of years?

@Charles - I wonder why they decide the durability of the battery in miles, why not in years. Does cheap material again reduce the durability / life of the battery?

@Charles – It could be a miracle if it could be done, it would definitely reduce the price of a hybrid vehicle making it more affordable. Most of the users are afraid to by a hybrid due to the battery replacement cost.

@davetrowbridge – It sounds interesting, we a re all looking for ways to reduce the cost on these systems. As technology develops I'm sure there should be an affordable way to do the same thing in a different way.

@apresher – I don't think the battery manufacturers would provide a service agreement to protect against catastrophe. It's not that they can't do that but simply they don't want to take the burden. I am using a Toyota Prius Hybrid but didn't get such service agreement.

@Charles – yes replacing a battery costs a lot, you feel better when you hear that a battery could be used for 15 – 20 years. I wonder if this is the same for all the brands in the market. I am sure the cheaper ones are low in quality and would not last this long.

@Rob – Yes its indeed good news that we could use a hybrid battery for 15 – 20 years. As you said we might use a car for 8-10 years maximum, and the battery costs a lot when it comes to a hybrid car.

Accelerated Testing

There was speculation that accelerated life testing increases temperature which artificially shortens battery lifespan. Would it be possible to incorporate cooling during accelerated testing to determine life span data at more reasonable temperatures?  I'm thinking that life testing has already been performed at cooler temperatures (which would prove/disprove this hypothesis).

Can EV Batteries Last 20 Years?

I'd be suprised if Lithium ion batteries made today will last that long.  They have made giant leaps forward - particularly in terms of weight to power ratio when compared to lead-acid or nickel-cadmium.  Eight years sounds more realistic if they are maintained and kept cool...
