Harley-Davidson ® FLH, FLT, FLR Series (Touring) (1997 - '25) Motorcycle Batteries

The Harley-Davidson Touring lineup, which includes the Road King, Street Glide, Electra Glide, and Road Glide, represents the pinnacle of long-distance riding. These "Big Twins" require a battery that can handle more than just a high-compression start; they need to support premium audio systems, GPS, and security features without breaking a sweat.

At Battery Mart, we recommend the Big Crank ETX30L as the definitive choice for the 1997-2025 Touring generation. Proudly made in the USA by East Penn (Deka), the ETX30L delivers a massive 400 Cold Cranking Amps (CCA). This is the same high-performance AGM technology used in the original equipment, ensuring your bagger has the punch it needs, even after a cold night.

Why the Big Crank ETX30L is the Touring Standard:

  • Massive 400 CCA Output: Power to turn over the largest Milwaukee-Eight® and Twin Cam™ engines.
  • Vibration Resistant: Heavily reinforced internal components withstand the "shaking" inherent to V-Twins.
  • Leak-Proof AGM Design: Protects your bike’s paint and chrome from acid damage.
  • Ready-to-Ride: Arrives fully charged and ready to install.

Definitive Power for the Long Haul: FLH/FLT Battery Guide

Your battery is the most critical component on your motorcycle. The 1997-2025 Touring series utilizes the 30L-style battery frame, the largest standard battery size in the powersports world. This size is necessary to provide the reserve capacity required for modern touring amenities.

The Big Crank Advantage

The Big Crank ETX30L is widely regarded by Harley enthusiasts as the best value-to-performance replacement on the market. Manufactured by East Penn in Lyons, Pennsylvania, it features specialized molded-in terminals that won't vibrate loose, preventing a common issue among inferior batteries. It is the exact fit for the battery tray of your Road Glide, Street Glide, or Ultra Classic.

Frequently Asked Questions

What is the correct battery for my 1997-2025 Harley Touring bike?

Models including the Road King, Electra Glide, Street Glide, and Road Glide within this year range almost exclusively use the ETX30L (or 30L-BS) battery. This includes engines ranging from the 88ci Twin Cam up to the modern 114ci and 117ci Milwaukee-Eight.

Should I choose an AGM or Lithium battery for my Bagger?

For most touring riders, the Big Crank AGM is the preferred choice due to its proven reliability and ability to handle constant electronic draws. However, we do offer high-output Lithium (LiFePO4) versions. Lithium is an excellent choice if you are looking to shave roughly 15-20 lbs off your bike's weight or if you want a battery with a very long shelf life during the off-season. Contact us or consult with an authorized Harley dealer to ensure a LiFePO4 Lithium battery is a great option for your motorcycle.

Why is 400 CCA important for my Harley?

Large displacement V-Twins require significant "breakaway" torque to move the pistons. A battery with a lower CCA might struggle during a start, especially in cold weather or when the engine is hot. The 400 CCA rating of the ETX30L ensures an immediate start every time.

Do I need a special charger for my Touring battery?

To maximize the life of your battery—which can often last 5+ years with proper care—we recommend a smart lead-acid maintainer (like a Battery Tender) if the bike sits for more than two weeks. This counteracts the "parasitic drain" from the bike's ECU and security system.
