Trying to get a little background info on battery life. I am looking at the Civic Hybrid and notice they warranty the battery for 4 years or 80,000 miles. At 80,000 or there abouts should I expect to have to replace the batteries at a cost I can only guess at of 1500-2000 dollars. Appreciate any help I could get. Thanks

Figure that a waranty, like any form of insurance, is actually a form of gambling. In this case, they are betting that the battery will last at least 4 years or 80,000 miles and you are betting that it won't. Since they are making up the terms, and they know that different batteries will last different amounts of time even if conditions were the same, and in these cars conditions will NOT be the same. They have to figure they can afford for some of the batteries to go bad, but they want to minimize that number.

Some batteries might make 8 years, 160,000 miles or more. Some might make 3 years, 60,000 miles. The waranty just tells you that you can depend on getting that much out of the cost of one battery. It is a "limited" waranty, so, I believe, you pay for the portion of the battery life you got and get refunded the portion of the expected battery life you didn't get. If the battery lasts half as long as they guarantee, you pay half for a replacement.

Apparently, exceptionally hot climates shorten battery life, unless you actively defeat the heat buildup in the car while it is parked (hence all the discussion here about tinting in Florida).

It seems to me that the Insight came with an 8 year battery warrenty. I wonder if Honda is secretly replacing packs?

But honestly, I wouldn't worry too much about the batteries. Most people expect them to last the life of the car, and from what I have heard there have been very few documented Insight pack replacements...

Though the cost of the pack will certainly be more then $2000...

People have gotten individual batteries (pairs?) replaced after the IMA light has come on in their Insights. It has been reported on the Yahoo! groups.

I had My battery pack replaced at about 60000 miles and it was totally covered by waranty. But heat is a definate factor in battery life, I notice with summer coming on and temps hitting 100+ I tend to show a lower battery charge on My Insight and on the wife Insight but after the day cools down they both tend to hold a higher charge.

I notice the same thing in Arizona, but I think it perhaps has more to do with the demand put on the car by the AC. It's not that the Insight uses any more power for it's AC than any other car, it just makes more of a difference on such a limited powered car. You tend to push down the gas pedal more while accelerating to keep the same acceleration that you did without the AC and that results in more assist.

The assist seems to cut out after 3000 rpm when not in heavy throttle positions so I try to keep it reved while accelerating durring the summer and try the best to keep it on the cam and not the IMA. There is an art to it, but you can keep the charge up durring the summer by keeping it reved while accelerating and then eeking every last bit out of regenerative braking.

It hit 107 yesterday so I was just trying to get back in the summer driving groove and I did end up down to about half charge showing in the meter and some force charging at a couple points of the journey.

Still, due to the heat I would not be suprised at all if I need a new pack before the 80,000 mile warranty is up. I have heard of another owner in the valley that also needed a battery replacment done. Not sure the exact mileage, but I think it was more like 50,000 miles and it got to the point where he was having one or two recalibrations on his way to work each day and it finally triggered a IMA ligth which was the dead battery code so they replaced his pack finally.

See my theory is the Japanese built this car for their climate more and never really considered the desert southwest very much. Ideally some sort of water jacket on the batteries would be awsome as it is not hard to get the pack in to thermal cut back as it is. I think heat is one issue that may need to be addressed.

The Insight compensates for extreme cold by charging the battery pack and thus heating it up. It cannot compensate as easily for heat.

This is definitly true. I have seen very aggressive charging when I start the car in the morning during winter. Accellerating down my street (which would normally be under assist) results in 4 or 5 bars worth of charging...

If Honda has lowered the warranty period on the Civic Hybrid, that should tell you something. Maybe they have had to replace more battery packs than they realized they would.

Now your only protection will most likely be an extended warranty. Meaning, you buy this in the hopes that something goes wrong, to get your monies worth.

Wait, I know we retired this post, but I'm seeing 8 years 80,000 miles on the civic's hybrid components. Where did you see 4 years?

The engine warranty ends at 36,000 miles. Does that mean the engine will die immediately afterwards? Of course not! :) Today's engines last 200,000+ miles.

Same applies to the battery. I fully expect my battery to last the life of the car. It might be a little "weak" at 200,000 miles, but it won't be completely dead or need replacement.

I live in Southern California. Should I consider getting a car cover to protect from heat while parked on the street. I work nights so my car sits on the curb all day before I head to work in the evening.

Try covercraft. They even make a custom fitted cover for the insight. I've got one to help battle the heat, but I think in the end there is no winning against the desert, but it helps.

Anyway, they make several types. I got t tan flannel one because it is the softest most gentlle to the paint. Only problem is it can't get wet.

I don't use a car cover but do use the vent shades and reflective tint? The vent shades allow you to keep your windows down about a inch without worrying about rain so the heat doesn't build up as bad. The reflective tint also cuts down on the heat entering the car. I wish I had put them on before my first summer with the Insight. Have fun, Rick
