Harley-Davidson ® Street (2014 - '21) Motorcycle Batteries

Reliability for the Modern Commuter: XG500 & XG750 Battery Guide

The 2014-2021 Street series was built for high-volume global markets, making it one of the most prolific modern Harley-Davidson platforms. Because many of these bikes are used in rider training programs or for short urban trips, the batteries are often subjected to frequent start-stop cycles. A premium AGM battery like the Big Crank ETX14L is essential in these conditions, as it offers superior recharge rates compared to budget alternatives.

The Big Crank Advantage

The Big Crank ETX14L is the preferred replacement for riders who want factory-plus performance without the dealership price tag. It features a patented terminal design that ensures a flush, vibration-proof connection. For the Street 500 and 750, where the battery is tucked neatly into a compact frame, the leak-proof AGM construction ensures that your bike’s finish remains protected from corrosive acid vapors.

Frequently Asked Questions

Does this battery fit the Street 500, Street 750, and the Street Rod?

Yes. All models in the Harley-Davidson Street (XG) family from 2014 through 2021 utilize the same ETX14L battery footprint. This includes the standard XG500, the XG750, and the higher-output XG750A Street Rod.

Is this battery an upgrade over the original factory battery?

Many riders find the USA-made Big Crank ETX14L to be a significant upgrade in terms of longevity and cold-cranking performance. While the factory battery is designed for standard use, the Big Crank uses higher-density lead plates and premium separators to provide more consistent power over a longer lifespan.

Can I use a Lithium battery in my Harley Street?

Yes! Lithium (LiFePO4) is a popular choice for the Street series, especially for those looking to improve the bike's center of gravity by removing nearly 8 lbs of weight. Lithium batteries also offer a very low self-discharge rate, making them ideal for riders who don't get to hit the road every day. If you choose lithium, be sure to use a Lithium-specific charger.

How do I maintain my battery if I only ride in the city?

Short city trips often don't give the motorcycle's charging system enough time to fully replenish the battery. To prevent a dead battery, we recommend using a Battery Tender once a week to ensure the voltage remains at peak levels. This simple step can double the life of your battery.
