Yep, I bet it was very similar. I looked up a Magnum (without knowing your specifics) and they listed a Group H7. Mine was Group 79. But anyway, same kind of thing. I installed it and tested it. With 840 cca it tested to well over 1000cca and it was only a little over 60% charged. My old one only tested to 654cca. I should be good to go. I noticed the date tag and it was stamped Jan 19. It should be a fresh one.
