Had a problem with my on-board charger during a recent tournament weekend. I bought this battery as a back up...just in case. I did not need to use it...it just sat in the boat. it is fully charged. An O'reilly Super Start Marine Deep Cycle Group 27. I have the receipt that is good for $22.00 core chage refund if you have an old battery to turn in
