Hi, I'm new on the list, just having bought my 2001 Insight 3 weeks ago. Does anyone have experience with how many weeks you can leave an Insight sitting without running the IMA battery down to the point of damaging it?
I have a spare IMA battery that I had sitting in my garage for over a year before I started using it. No harm done, it even had some charge left!
I think unless you are talking about a year or more, I wouldn't do any maintenance on the battery while stored. In fact, the little lead-acid 12V battery would need more maintenance than the big 144V NiMH.
Only suggestion: charge the battery to full before storing the car if it's more than a couple months.
