    no you will need 38 gen 2 modules!

    Yes. It looked great.

    Re-Involt paints it on the packs that have NHW20 modules. Considering there is a cost difference of several hundred dollars, it may help in inventory control.
    It has 38 modules and just as heavy! But getting a rebuilt battery pack from one or two rebuilders makes a lot of sense. They are able to carry the 10 extra modules as inventory and have enough after every four, NHW20 backs to build out another NHW11 pack:

    • 1st NHW11 = two, NHW20 packs, 10 left over modules
    • 2nd NHW11 = two, NHW20 packs, 20 left over modules
    • 3d NHW11 = two, NHW20 packs, 30 left over modules
    • 4th NHW11 = two, NHW20 packs, 40 left over modules
    • 5th NHW11 = 38 modules, 2 left over modules
    Daryl, the 2001 owner, installs solar heating and photovoltaic systems and called Re-InVolt. One of the things we both appreciate is Re-InVolt tests the modules, measuring their Ahr capacity and builds matched packs.

    One of the risks of buying any two NHW20 packs is having mismatched modules. This can lead to an early failure for the individual, pack builder and something that bothers me.

    Hi Bob & FWD,

    I realize that the Re-InVolt Classic battery has 38 modules and will weigh around the same as the original equipment battery.

    What I meant to ask was that the 2G traction battery should weigh around ~75% of the Classic traction battery, since the former has fewer modules. Do you agree?

    I would expect:
    73% - relative module weight for NHW20 under NHW11
    equal weight control electronics
    slightly ligher case - less length

    The term "full charge" is misleading.

    The Gen 1 battery pack will not see 100% charge during normal operation.

    Four bars does not indicate 100% charge.

    Yes, I understand that means ~80% state of charge, just as no bars means <=40% SOC.

    However, it is "100%" from the point of view that the gauge won't read any higher.

    It would have been easy for someone to read your previous post, in which you had posed the question:

    and incorrectly infer that 100% SOC can be attained by the Gen 1 battery under normal conditions.

    This really is a two man job (Ok, girls too) but not just because of the heavy lifting:
    It is so much more fun when folks collaborate on projects and build something.

    I was showing pictures of the battery replacement at work and one of the biggest hybrid skeptics was at first mute. The 250,000 miles and $1,700 for the battery including shipping kinda pole axed him. But he dredged up, "Well you still have to calculate that against the mileage."

    So let's see:

    • 10 years of service
    • $170/year accumulated cost of traction battery
    • 25,000 miles per year of driving
      • 46 MPG - mileage estimate from users at EPA site
      • 37 MPG - Echo mileage, another 1.5L Toyota
    • 133 gallons avoided per year, 676 - 543 gallons
    • $266/year fuel savings per year at $2/gallon
    • ~$100/year saved per year including battery
    This is a conservative estimate. If I used a Corolla, 30-33 MPG, the savings become even greater. Although this one car history is anecdotal, it punches a $100/year hole in this common, hybrid skeptic claim.

    The Echo and Corolla both cost thousands less than the Prius in 2001.

    The important thing is that the owner is happy with their car.

    There are many ways of dealing with hybrid skeptics but as a general rule, address what they know and relate you're hybrid experience to something they can understand.

    Explaining that the traction battery is part of the transmission goes a long way to helping them understand what is going on. They can then relate the $1,700 to their own experience with automatic transmission repair costs. They were especially impressed with the 250,000 miles.

    That's all well and good, but if you give them funny numbers, and they catch it, they are much less likely to be impressed.

    You had stated that a ~$100 per year savings is achieved by driving a Prius that gets a rebuilt battery at 250K than by driving a Toyota Echo for the same mileage over the same amount of time.

    While most folks don't keep a car for ten years or 250K miles, those that do may note:

    2001 Prius MSRP: $19,995

    2001 Echo MSRP: $12,000 if you really loaded it up

    With the Prius selling at a ~$7K to 8K premium over the Echo, the ~$100 per year savings is more than erased by the ~$700-800 per year initial cost premium, not including the cost of financing.

    The Echo will have slightly higher maintenance costs than the Prius, but nothing to overcome the MSRP.

    The 2001 Prius numbers are:

    • 250,000 miles - exceeding the often claimed 109,000 miles from CNW Marketing
    • $1,700 traction battery cost - well under the often quoted $4,000
    • 4 hours, two owners - a half-day effort to replace the battery
    The office skeptic wanted even this much lower battery number to be counted against the milage. If he brings it up again, I'll be able to 'napkin' the numbers easily enough.

    As for your concern about total cost of ownership:

    Interesting, it turns out the Consumer Reports article for 2010 is available here:

    The 2004-2009 Prius info doesn't apply to your comparison of a 2001 Prius with a 2001 Echo.

    The only numbers that matter are:

    • 250,000 miles on the Prius
    • $1,700 battery replacement cost
    • two people, four hours labor to swap
    The office skeptic wanted the traction battery price factored into the fuel costs ... problem solved. The Consumer Reports article is for your benefit.

    If the topic is total cost of ownership (now opened in another thread) then the similarities among Prius models is much more important than their differences.

    I'd fully expect all Prius models (except perhaps the NHW10) to do very well in depreciation, fuel cost and maintenance costs. All data I have seen for Prius supports this. These are the categories where different car models can offer different TCO.

    Except insurance, should one select a car model that is red lined there.

    Hi Doug,

    This had been true until recently. NHW20 models have taken a pretty big depreciation hit with the introduction of ZVW30, bad publicity, ~700K units produced over six model years, etc.

    For example, take a 2007 Prius package #3, MSRP of $25,350. Three years later, and having logged only 18,600 miles, KBB dealer trade-in value ranges from $13K - $15K.

    You are almost certainly correct in that assumption.
    No one in this thread suggested that anyone do that.

    But you don't have to be a millionaire to go to a Toyota dealer.

    No. On his initial visit, he concluded that the battery pack was marginal. However, he was unable to condemn it. The battery pack failed soon afterward. But had he understood the system, he could have performed a comprehensive HV battery test using only his miniscanner gadget and the owner's printed service information.

    And although his device apparently cannot read freeze frames, it is possible that a quick look at that information would have made even the correct battery test unnecessary. His solution, however, was to erase that information, although there was no benefit in doing so.

    Actually, it's a wee bit more complicated than that.

    Again, this vehicle could have been diagnosed correctly the first time, using only the equipment at hand.
