Re: What will happen to my IMA battery if I dun drive for more than a month?
Based on things I've read on the interweb (so you know they are true), it is a good idea to start your car at least once a month and run it for a while. I seem to recall someone who posted here about a battery failure that happened in a car that was driven very infrequently.
I understand that NiMH batteries don't like to be fully drained, which is what will happen with time if you don't drive. I don't know how long it would take for a failure to occur, it's not worth messing around with when all it takes is a drive around the neighborhood every month to prevent this kind of battery strain.
