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: |

Customer Reviews
In 2018 I purchased a used 2008 Suzuki V-Strom 650. The previous owner told me the battery in the bike was five years old. Five years later, I'm finally in need of a replacement battery.
I live in Oklahoma and the heat is very hard on batteries. I do keep my V-Strom in the garage and I use a trickle charger to maintain the battery. Still, 10 years is a long time for a battery to last.
I definitely recommend Big Crank batteries.
I bought my first Big Crank several years ago and just now needed to replace it. I didn't hesitate to install another one. Strong and dependable.
Is not just an easy bolt in application on a 2007 Suzuki 650 SV. The battery IS the perfect size, but either the battery posts or cable ends need to be modified in order to use it. I added a slot on the top of each battery post so the stock battery cable ends would sit down properly onto the battery posts. I want it kept stock so future battery replacements will be just a simple swap out.
That said, it is a nice strong battery that really cranks the motor over fast for easy start ups.
Found one of my Triumphs with a dead battery. Ordered 2 Big Crank ETX12. If you have a Street Twin or Bonneville This is the battery that fits. You will need to alter the top plastic hold down bracket slightly. The other 2 batteries that are listed have dimensions that will be difficult to fit. Anyway, great battery and super fast shipping!
Perfect fit - quick shipping - great price - great customer service. This company is great!
Seems to be a great product and value for the price. A faulty regulator killed off my 6 yr old battery in my '07 Triumph T100. I'm back in action with a new regulator and this power-packed Big Crank! And its made in the USA not China!
I bought this batter y to replace the last Big Crank I bought 7 years and 40k miles ago. The last one got me home and then perished, haven given it's all. Zero problems or issues throughout it's long life. When this one passes away over 5 years from now, I'll buy another!
