8) :) :shock:

I'm curious whether anyone has done any battery maintenance on their Insight (if so, what?) and /or has noticed a problem like this:

I bought a used (2000) Insight in April '03 (now about 33, 000 miles). At that time, it had a lifetime mpg of 52.1, which seems pretty low for an Insight. I was getting about 58-59 avg. mpg (in mixed driving; 62 on longer highway trips) after I bought it, so I figured that I was a smarter, better driver than the folks I bought it from. Ha! Eventually, the lifetime mpg peaked at 53.8.

Since then, I've noticed a significant drop in my average mpg (I generally hit the trip button each time I fill up gas), down to 49-52 when doing mostly city driving (lifetime mpg is now at 53.5). I wonder if my mileage drop has to do with the batteries. When I did a 50 mile highway trip 3 days ago, my batteries were well charged and I got great mileage (58). Ever since, my battery meter has stayed at 3 bars and I've been getting lousy mileage.

Note: the mpg decrease seems to coincide with cooler weather. I live in Ohio.

I'd love to hear your thoughts and experiences on this matter. I've read posts about the effects of a/c, tire pressure, and climate on mpg; here I'm wondering specifically about batteries and mpg.


Thanks! :D

Hey, Ricky, you're so fine...

Ricky,

Thanks for replying to my post about batteries and mpg! I really appreciate your time and suggestions. I will give the force charge a try. The battery level has been going up and down some, but last night I noticed it was at three bars again.

To my knowledge, the batteries have not been recalibrated. This task is not on the maintenance schedules I have (Insight Central, owner's manual); the only way it would have been done is if it's part of the regular maintenance schedule at 22,500, 30,000, 25,000, etc. that the dealers do. If so, then it would have gotten done between April of this year and now.

I've lived in homes with batteries hooked up to solar and wind equipment, and we always had to maintain and check the acid level; that's why it surprised me that it's not on the maintenance schedule.

I have 33,000 ish miles on my 2000 Insight, so I am still under warranty.

What is the hot air mod you spoke of?

Thanks,
Chris
