According to Watchdog's website, the replacement battery is a Group 27, but the measurements of the battery match the length of a Group 24. To know for sure, you would need to measure the inside of the battery box and make sure this battery would fit. The terminals on either a DURA12-80C/FR or a DURA12-100C/FR would match the original battery closer, but if you are wanting to upgrade to a deep-cycle battery the DURDC12-80P or the DURDC12-100P would also connect easily with the included hardware. Check the dimensions inside the battery box to see which group size will work best for you.
