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.
The Big Crank ETX20L Battery has become extremely popular because of the value it provides.

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.

Awesome product - came fully charged, no need to put on charger to bring up to bike voltage specs - EXACT size of old battery, fit beautifully - battery posts were tapped so no need to fight with aligning bolt to nut - really, can't say enough good things about this battery AND especially liked that it was made in USA!
