USA-Made Big Crank™ ETX30L Battery FAQ
What's the difference between the ETX30L and ETX30L-A batteries?
They are the exact same battery. The only difference is that the ETX30L-A model includes a removable height adapter, noted by the "-A" in the part number. The adapter allows the battery to fit applications that require a taller profile. Our Big Crank™ ETX30L battery includes this height adapter/spacer in the box, making it a universal fit for both applications.
Will the Big Crank™ ETX30L fit my Harley-Davidson® motorcycle?
Yes, this battery is a popular choice and a direct-fit replacement for many Harley-Davidson® Touring models, including:
- FL, FLH Series (Touring): 1997–2010
- FLH, FLT (Touring): 2011–2016
- FLH, FLT Series Touring: 2017–2020
- CVO FLH (Touring): 2007–2020
It's also ideal for many other motorcycles, ATVs, UTVs, personal watercraft, and snowmobiles that use this battery size.
What other battery part numbers does the ETX-30L replace?
The Big Crank™ ETX30L is a direct replacement for a wide range of batteries, including part numbers from other brands like Yuasa, Power-Sonic, and Deka. Some of the most common cross-reference part numbers include: YIX30L, YB30L-B, YTX53030-BS, CTX30L-BS, MTX-30L, CB30L-B, 66010-97A, 66010-97B, 66010-97C, and 66010-97D.
Is this an AGM or a lithium battery?
The Big Crank™ ETX30L is an AGM (Absorbent Glass Mat) battery. AGM batteries are a type of lead-acid battery that is sealed, maintenance-free, and offers excellent durability and vibration resistance. If you are looking for a lighter-weight, higher-performance alternative, we also offer a variety of lithium batteries in this size.
What's included with the battery for installation?
We include everything you need for a simple and secure installation. The box contains the fully charged battery, a removable height adapter, new bolts, and brass spacers. The spacers are designed to provide a flush connection for your cables on the recessed terminals.
Is this battery truly maintenance-free?
Yes, it is. The Big Crank™ ETX30L is a sealed AGM battery, so it never needs to have its water level checked or refilled. Just install it and you're ready to go. We recommend keeping the terminals clean and using a battery maintainer during long periods of storage to ensure maximum lifespan.

Customer Reviews
Great company, great service, easy website to order, fast shipping.
Put it in a 2014 cvo ultra, starts very strong, I buy all my bike batteries here
Last one purchase July 2016 for my 2005 Road King Custom. Just noticed this date of 5/8/2026 that the CCA decreased to 365 from original 400. Typically kept it on a battery tender when not in use. Can't complain about lasting almost 10 years. So with that luck, I guess its time for a new one. HIGHLY RECOMMENDED!
Started the four wheeler with ease.
This is the 3rd bike I put this battery in.
I’ve always run Deka branded batteries in my bikes. After friends gave me positive feedback on Big Crank branded batteries I figured I would try one out in my Ultra Limited. Delivery was faster than I
expected which was nice.
Works great in my 2015 Free Wheeler, nice crank power.
