Tech Tip: Easy Front Mount Installations
This battery is supplied with unique terminal hardware (2 spacers and 2 bolts for cable to terminal connection). This hardware is required for proper installation on certain applications. Other hardware may damage terminals and should not be used. The spacers are required for front mount cable installation only!

Customer Reviews
THE BATTERY WERE A PERFECT FIT AND READY TO GO. FOR THE PRICE ITS WAS IN MY RANGE.
drops right into place has plenty of cranking power.
Been using Big Crank but they were back ordered, so I purchased the Mega Crank. Looks about the same as the BC except the posts are a little smaller. Installed on my 05 Deluxe with no problem. Fired the bike right up . If it last as long as the Big Crank ,I'll be happy. It also was a little bit cheaper in price which is always a bonus.
Perfect fit at a great price! I get most of my bike batteries from Battery Mart.
Have ordered many Items..batteries/ chargers from battery mart! Quickest and least expensive bang for the buck! Especially now with retail stores not being able to restock their shelves.. Both Walmart and Sam’s Club did not have the battery I needed!
I've had one of these same batteries in my Harley for five years plus with zero problems. When it came time to replace the one in my Gold Wing, there was no hesitation which brand to buy. Great battery, great price, fast shipping.
I bought an ‘02 Honda GL 1800 a year ago. Second owner wasn’t sure how long ago the battery was replaced. Well I should have known better and after a year it went dead. Fortunately my brother in law had a set of bike jumper cables and I got it running to get the 60 miles home. I ordered this battery that day. Arrived in 2-3 days and has the juice to start the bike. For 3-5 years hopefully.
