I cross posted this inquiry as a reply in the thread titled hybrid battery grid charger but thought I should also make a new post with same info. sorry if this is bad form- just a desperate Newby. I am having a problem with my Honda Insights IMA batteries dying. Here is a summary. I gratefully welc…

It makes no economic sense drive a hybrid 2-6,000 miles a year. 6000 miles at 70mpg and $2.50 per gallon is $214 fuel cost. Same with 35mpg is $428 fuel cost. So a regular Civic, Corolla etc. will cost an extra $214 per year in fuel. Insignificant IMO. I drive a Toyota Matrix ~6,000 miles per y…

For those who don’t know (I had to look it up), “IMA” is a brand-specific acronym that stands for integrated motor assist.

Buy the grid charger. Hook it up once a week for about 36 hours. Terrific device that brought back 16 year old batteries after being dead and sitting in a field for over 2 years. Grid charger is the best.

Same problem with my 2003 Insight. Its third IMA battery lasted 3.5 years, just until after the end of the warranty. IMA and CEL are on. The car is running fine. The 12V battery is charging and its battery light does not come on. Gas mileage is ok, 30+mpg short distance city driving, I haven’t ta…

Disconnecting the 12 volt battery for a short time and then reconnecting it resets the IMA and CEL lights, and everything works fine for a few months, and I passed smog inspection. I have done this maybe a dozen times in the past two years, the IMA battery is now 5.5 years old.

I read your previous post Your car doesn’t even get a tailpipe test . . .

Btw, unless you are talking about some custom IMA charger, hooking a trickle charger to your hybrid wont make any difference to your IMA battery. It only affects the 12v battery. Two separate systems.

I’d replace the car, too. My Ford hybrid cautions against any long periods without driving. I image that’s contributing to your frequent battery failures.
