I am replacing the batteries in my Force and will soon (a few weeks) have 13 Deka dominator 8G27 group 27 gel batteries for sale. They were made in late 2001. I can use about 20 AH over the course of an hour driving. One of the batteries appears to have leaked (or perhaps it was a previous battery in that spot).
I live in Sharon, MA. The easiest would be for you to pick them up here, but we might be able to deliver them somewhere in the Boston area.
Make me an offer. I'll take the best offer I get before the new batteries arrive.
