I was just wondering from the personal experience of you all.... How long has your battery lasted so far or did it crap out already? if so, what mileage and why do you think it did?

oops i didnt see that there was other battery posts... lol
oh well... Any extra information postings would be nice though. How many MPG do you think the honda insight gets without a IMA battery on a manual tranny?

Hyper MPG (highway) will be almost identical. The city drive cycle may suffer 10% +- w/o auto stop.

The biggest "problem" isn't MPG. Since the IMA and alternator functions are integral the IMA battery will eventually require replacement to allow proper 12v operation. They 2 systems are interdependent and there have been credible reports in here that confirm the above.

Adding a conventional 12v chargins system won't be easy and even more so if your AC equipped (no location for alternator mounting).

HTH!
