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.
How A Front Mount Looks when Installed:
I have had trouble starting my Darkhorse stage 3 04 FXST since I did my stage 2. Been threw OEM and several after markets. This thing doesn't drag at all. 32 degrees this morning and lit off the first time. I love it. Big Crank is the only battery I'll run if it last.
I buy these for my own motorcycles and customer's bikes as well.

Bought this for my 2004 Harley Davidson wide glide fires right up fast. Great battery will definitely buy again great pricing
Low cost and great quality has never let me down. The only aftermarket battery I ever used on my FXDB DYNA.
I've purchased batteries from Battery Mart in the past and they've always fit my bikes perfectly. This one was for me 2018 Fatboy with a 114 CI engine. It fit perfectly and was same specs as the Harley OEM version. West Penn makes great batteries and it works perfectly
Best battery on the market hands down.
I've been buying these batteries for over 20 yrs. The last one in my Harley was four yrs old worked fine bought a new one because it was apart.
