I havent read through all of this posts on this page, just the first one. As in a previous thread I read that the hybrid batteries are not like cell phone batteries in that the car keeps the battery charged at least 50%. Once it gets to that level, it's supposed to recharge. Apparently you used it to the extent that it couldnt recharge fast enough and it dropped below 50%. As the other thread stated, this makes less wear on the battery. However, you have to look at the battery like a muscle. If you work out a muscle it stays strong. If you dont, it gets weak and can fail. I have found that you can ruin cell phone batteries if you do not run them dead once in a while. You are supposed to use all of the battery to give it a good workout and remain healthy. It's the case with a cell phone battery, and it sounds the same with your car battery. It still functions properly, hasnt really failed. The problem is just that the system in place doesn't allow the complete battery to get a full work out, only the upper half.
I am considering purchasing a 2007 honda hybrid now, and it is very good to know about this issue. Thanks!

Wow, it seems like everyone is having issues with the hybrid. Funny thing is i got 3 different prices for the battery w/ labor from three different Honda Dealerships. They want to take you for everything you got. Then you tell them you got a voucher and they say "oh i cant give you that price if Honda if going to pay $2400 of it" Really? Really? 4 Hondas later, IM NEVER BUYING FROM THEM AGAIN. TIME TO SWITCH TO THE LESSER EVIL bc they all are nasty dealerships.
