I am very, very, impressed with these batts. Goodtime and I pulled cranks for 6 hours this morning and when I got to the house the volt meter said 12.3 and the charge went to 68% when I hooked it up. I am using another trolling motor on the back as a kicker, but it's and older motor and wasnt helping a whole lot time we left. Not bad for 55 pound thrust motor on an 18 foot glass boat.Thumbs Up
