Need a battery. Never boondock. Recommendations?

You know, I went back and went over the OP word for punctuation and I could not make out heads or tails of the year, type of rig, or anything else. So for the life of me try as I might I cannot asssssssssssssume whether the battery was overcharged, undercharged, inner charged or outer charged. He asked about a battery recommendation. That part I got straight.
