Looking for 12 volt batteries for my John Deere E90. Don't have any experience with 12 volt deep cycles. I have bought 6 volt Trojan T-105's in the past for my Wheelhorse and they have given me great service. The dealer I use doesn't have any group 24 Trojans and is recommending a Deka DC24. Any opinions on this battery, or recommendations on others? Thanks; Dennis Elsberry, MO
