Harley-Davidson ® XL, XLH (Sportster) (1987 - '96) Motorcycle Batteries

Vintage Performance: Sportster XL/XLH Battery Guide

The 1987-1996 Sportster generation uses the "20L" battery footprint, which has become the industry benchmark for high-performance cruisers. For owners of these classic Evolution models, moving away from old-fashioned flooded batteries to a modern AGM unit like the Big Crank is the single best maintenance upgrade you can perform to ensure electrical reliability.

The Big Crank Advantage

The Big Crank ETX20L is the preferred choice for Harley enthusiasts who value durability. Unlike budget imported batteries that use thinner lead plates, the Big Crank is built with heavy-duty grids and high-density oxide. This results in a battery that not only provides a factory-perfect fit but also survives the extreme heat-cycling and road vibration that classic Sportsters are known for.

Frequently Asked Questions

Does this battery fit the 883, 1100, and 1200 Sportster?

Yes. Throughout the 1987-1996 production run, all XL and XLH models utilized the same ETX20L battery size. This includes the early 1100cc models as well as all 883cc and 1200cc variants. The 310 CCA rating ensures more than enough power to turn over the largest engines in this group.

Can I upgrade my classic Sportster to a Lithium battery?

Absolutely. A Lithium (LiFePO4) battery is a popular choice for custom builders and performance enthusiasts looking to shave roughly 12 lbs off their bike. Lithium batteries offer extremely fast cranking speeds and maintain their charge longer during the off-season. If you make the switch, ensure you use a Lithium-specific charger to keep the cells healthy.

Is the Big Crank ETX20L better than the original equipment battery?

The Big Crank ETX20L is manufactured by East Penn, the same American facility that produces many original equipment batteries for the motorcycle industry. It features the same high-performance AGM technology and patented terminal design, providing a premium fit and finish without the dealership premium.

What is the best way to maintain my battery when I'm not riding?

To ensure your battery lasts 3 to 5 years (or even longer), we recommend using a smart maintainer. Because these Sportsters don't have the heavy parasitic draw of modern security systems, they stay charged longer, but they still benefit from a Battery Tender to prevent the sulfation that occurs when a battery sits for long periods.
