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! The top mount position does not require the round spacers, use supplied bolts only. Torque bolts to 6 to 8 ft. lbs.
How A Front Mount Looks when Installed:
I have dealt with Battery Martin multiple times over the past few years and they have always been exemplary. Their prices are good, they have great selection and delivery is always expedient! I highly recommend them!
I ride shy of 100 miles daily 5 / 7 days. Took a vegas trip during the heatwave fathers day weekend. Temps up in the 116~118°. Battery stopped outputting power in death valley, even though showing a 12.8v charge. Got some help and found a used battery and that got me the rest of the way and home fine.
This one kicked like a mule when it was working for the last few months when i got it =). Maybe i got too overzealous with the summer ride.
I ordered the wrong part and they were professional and accommodating in correcting my mistake. Easy to work with.
Installed this battery in my 08 Harley Davison, it is an extra replacement for what I had great price and US made.
Great battery wheeler started right up at -20 while out on the lake. Liked the made in usa part also
makes my sportster 1200 a happy girl. Way better than other companies batteries.
ive only had the battery for about a month but it has plenty of power for my Harley Davidson Fatboy
