The Big Crank ETX20L battery offers the most advanced power and value in the industry, and is ideal for ATVs/UTVs, motorcycles, personal watercraft, and snowmobiles.
Our competitors are so jealous of our American made Big Cranks that they list "Replacement for Big Crank" and try to substitute an inferior grade imported substitute. Be wary of cheap knockoffs, ONLY batterymart.com carries the wildly popular BIG CRANK ETX20L.

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.

ive only had the battery for about a month but it has plenty of power for my Harley Davidson Fatboy
On 10/25/20 I ordered a battery for a 2017 Harley Davidson. Not sure what happen but when I went to install on battery on 11/15/20, it didn't fit. The item number on the invoice matched the battery I received. Not sure how I order the wrong battery but it happened. I email BatteryMart on Sunday 11/15/20 and received a reply back that they would help me resolve the issue. On Monday I received an email from Ashley in customer service asking what they could do to help resolve the issue. Great customer service. I will be back.
I've got 5 bikes and two Harleys. Over the years I've found this is the best battery for HD, for the money.
Great battery, fast delivery, came fully charged, Harley wanted over $300.00, I purchased a Big Crank Battery, fit perfectly, cost $104.00, I highly recommend Battery Depot.
Good prices and prompt delivery. The big crank battery fit right in the very exacting space in my Dyna. It fired right up and has worked fine so far. I have only had it a couple weeks. No reason to think there’s going to be a problem.
This is my second purchase from battery mart this battery is starting my bike.
Good selection, easy to navigate website,nice customer service when I had to call with questions, shipping was quick. Very satisfied and would recommend to anyone.
