Yep, my battery is leaking. My tractor is a 2006 and noticed over the winter the corrosion. It's still under warranty but thought I would clean it up and replace the battery myself. I logged on to search about the Optima but all I can find are the threads about it being discontinued. Figured Deere would just replace with a new battery which would just leak again. Are there any options for replacement batteries that wont leak? Also has anyone had any luck with new batteries from Deere? Thanks for any help.
