It may not feel like it just yet, but colder weather is coming. And when it does, some drivers will inevitably find out they need a new battery the hard way—when theirs fails to start the car.

We’ve just completed our latest round of battery testing, and we’re working on a story with our latest car battery Ratings and buying advice for the November issue of Consumer Reports. And here’s where we need your help.

Do you have a car battery story to share? Perhaps a sorry tale about being inconvenienced by a battery failure? Part of what we're reporting on is why car batteries often go dead in cold weather, so stories along those lines would be helpful. It doesn't have to be a "dark and stormy night" sort of thing, but that might not hurt, either.

Stories and authors chosen will be mentioned in our report in the November issue of Consumer Reports.

You can submit comments here, or use the Cars forum threads in the Aftermarket discussion and in John’s Tool Box (free to read, subscribers-only post).
