Tech Tip: Easy Side 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 side 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 Side Mount Looks when Installed:
This is the third big crank I’ve purchased. All 3 were for different vehicles/equipment. Always have been very pleased with the performance right out of the box and shipping is fast.
Great selection of batteries, and easy to find the exact size to fit my custom application (77 ironhead chopper). Looking forward to receiving my new battery, hoping it cranks right up. I will follow up if any issues..
Have had this battery for about a month, so far its great, it spins the crank up way quicker than the old Parts Unlimited Battery.
(Will update if anything changes)
I think this is the third Big Crank battery I've purchased in 10yrs of motorcycle commuting. Other batteries let me down after 1yr or less in use.
Always had great reliability and performance from this brand.
Easy to order, received battery in 3 days. It works great.
I ordered this battery to replace the original in my 2016 Triumph Street Twin. This is a direct replacement for the original battery, it took me no more than 5 minutes to install the Big Crank and no more worries of my battery dying in the middle of a trip. Just a great battery that does what it needs to do.
Incredible helpful service from the entire Battery Mart team, definitely will be recommending to friends and family!
Arrived overnight. Installed and went for a ride immediately.
