The ThrottleX Batteries HDX30L is the best battery for Harley Davidson because it’s a premium battery with super high cold cranking amps (CCA). It’s proudly made in USA and has nice performance and customer service. This battery is definitely a great buy.


Having a weak battery in your Harley is never a good experience. It can be very frustrating when you are ready to enjoy a ride but your Harley does not start. If you come across this problem even after you remove the battery and recharge it, then you have to buy a new battery. In this article, we will discuss how to find the best Harley battery to reduce the frequency of starting issues.

The degradation in performance of your battery is mainly caused by long term use of the battery and the low temperature of the operating environment. Basically, no matter what battery you buy, it will eventually fail to start your engine. But you can prolong the process of the degradation by using a battery with a higher CCA rating.

The CCA is short for Cold Cranking Amps. With a higher CCA rating, a Harley battery can produce and sustain more power. For people who usually ride in cold weather, it’s very easy to see the difference after using a high-CCA-rating battery. Also, big motors require a higher CCA. You can roughly equate the CCA with the performance of your Harley battery, so it’s not hard to understand why a battery with higher CCA rating is usually more expensive.

However, it’s meaningless if the CCA of your battery is much more than recommended, unless plan on adding extra accessories that demand energy. Adding aftermarket accessories may increase power requirements of the power, but there is no need to grab the highest CCA battery. You should also pay attention to the size, the capacity, the life span and the price of the battery.
