Harley-Davidson ® XL, XLH (Sportster) (1997 - '03) Motorcycle Batteries

Performance & Reliability: Sportster XL/XLH Battery Guide

The 1997-2003 Sportster generation utilizes the "20L" battery footprint. Because the battery in these models is highly visible and sits close to the engine, heat resistance and a clean aesthetic are paramount. A premium AGM battery like the Big Crank ensures that your motorcycle starts reliably while maintaining the classic look of your Evo Sporty.

The Big Crank Difference

The Big Crank ETX20L is the preferred choice for Harley riders who demand American-made quality. While many "big box" or budget batteries use thinner lead plates that fail prematurely under high vibration, the Big Crank is built with heavy-duty grids and high-density oxide. This results in a battery that not only cranks harder but survives the rigors of the road significantly longer.

Frequently Asked Questions

Does this battery fit both the 883 and 1200 Sportster models?

Yes. From 1997 through 2003, all Sportster XL and XLH models (including the Custom, Low, and Roadster variants) utilize the same ETX20L battery size. This battery provides more than enough power to turn over the 1200cc engine while offering extended reserve capacity for 883cc models.

How does the Big Crank compare to the original Harley-Davidson battery?

The Big Crank ETX20L is manufactured in the same USA-based East Penn facility that produces many original equipment batteries. It features the same high-performance AGM technology and specialized terminal design, offering a factory-plus experience and a perfect fit without the dealership markup.

Should I upgrade to a Lithium battery?

Lithium (LiFePO4) batteries are an excellent upgrade for riders looking to shave nearly 12 lbs of weight off their Sportster. Lithium batteries also offer faster cranking speeds and a slower self-discharge rate during storage. If you choose a lithium battery, be sure to use a Lithium-specific charger to ensure the battery remains properly balanced and maintained.

What is the best way to maintain my battery during the winter?

Because Sportsters have a relatively simple electrical system, they are easy to maintain. However, cold temperatures and long periods of inactivity are the primary causes of battery failure. We recommend using a smart maintainer like a Battery Tender to keep the voltage at optimal levels and prevent sulfation.
