Replying to: gagrice (Nov 22, 2004 10:55 am) I have been told that you may replace the battery a small section at a time, for about $150.00, if and when the battery fails///told to me by a Toyota manager. I found no reference in the USA article about $5000.00 for a battery, or any shortage...Toyota has been adding production an a high rate which was not anticipated and thus caused the battery pack backup....All the conjecture really is just that;;;conecture, and what if's....

Replying to: bjrich (Nov 22, 2004 12:10 pm) read the 8th paragraph. The whole article is about battery shortfalls. My experience with batteries tell me you may be able to exchange one cell at a time. However they usually go bad at about the same time, so you may be spending a lot of time replacing one cell every few weeks. |

Replying to: larsb (Nov 22, 2004 1:47 pm) You are right that we have not seen people complaining about battery failures. If they are like lead acid batteries they go bad about a month after the warranty date. :=) |

YOU DON'T NEED TO REPLACE THE BATTERY. Sorry to shout, but it seems to be the only way to get people's attention. The battery in a hybrid only uses ~30% of the capacity, so as to avoid causing internal damage, and therefore extend battery life = engine life. You won't have a problem replacing the battery, because you won't need to. Troy |

Replying to: electrictroy (Nov 23, 2004 7:42 am) You won't have a problem replacing the battery, because you won't need to." Hmmm, have any studies to support that statement? Specifically, ones that use the batteries in the same manner as the Hybrids? Just because they aren't drained like camera batteries doesn't mean they won't fail eventually, which is what you are saying.

In the lab - Toyota tested Prius to 200,000 miles with no degradation of the battery. In the field - Insights/Priuses exist with over 200,000 miles (see ebay for some examples). Expert opinion - I'm an electrical engineer. I've read all the research I could find, and it shows that a battery will last indefinitely, as long as it's held within 30-70% of capacity. This cycle avoids the under-and-overcharging that kills batteries & extends life indefinitely. . Now I admit that if you abuse your car (example: drag racing) it will kill the battery. But such abuse will also kill the engine. And the transmission. And the suspension. I don't think anyone here would abuse their car in that fashion. For us, the battery/engine/et cetera will last well past 200,000 miles. In fact, I expect the battery will last longer than the engine will.

Replying to: electrictroy (Nov 24, 2004 2:21 pm) "In the lab - Toyota tested Prius to 200,000 miles with no degradation of the battery." I'd like to see some independent studies, rather than from the manufacturor. "In the field - Insights/Priuses exist with over 200,000 miles (see ebay for some examples)." We do not know the state of the batteries in the Ebay Priuses. Hopefully, your independent analysis will prove true for the Hybrid implementation. |
