The Big Crank Advantage: Built for Performance and Reliability
At Battery Mart, we understand that when you’re out on the trail, the road, or the water, you need a battery you can count on. Our AGM (Absorbent Glass Mat) technology provides exceptional vibration resistance and a spill-proof design, which is perfect for the demands of powersports applications. Furthermore, the benefits don’t stop there.
Superior Cranking Power for a Strong Start
Say goodbye to hesitant starts. That’s because our Big Crank batteries deliver impressive cold-cranking amps (CCA), ensuring your engine roars to life even in challenging conditions. Just listen to what our customers are saying:
“Noticed a cranking difference on the first start (much better!), and so far so good.” – jwciv, for a 2019 Street Glide Special
Unmatched Durability for the Long Haul
Durability is paramount, and Big Crank builds its batteries to go the distance. Consequently, their robust construction and AGM technology contribute to a longer lifespan, saving you time and money on replacements. Don’t just take our word for it:

“I purchased Big Crank ETX30l in Oct 2018, it lasted until April 2025.” – Tim, for an Electra Glide
Designed for Your Ride: Flexible Installation
We’ve thought of everything. For instance, Big Crank batteries feature both molded top and side terminals, offering you greater flexibility when installing the battery in your specific powersports vehicle. This thoughtful design ensures a secure and convenient fit. As one satisfied customer noted:
“Perfect fit, nicely packaged, complete with new screws and delivered quickly.” – To, for a 2013 Tri-Glide
