Buying Guide: How to Choose the Best Batteries for Harley Davidson Motorcycles
As a Harley owner, I know that a dead battery can ruin a perfect riding day. Choosing the right one isn’t just about price; it’s about reliability, power, and matching your bike’s specific needs. With so many options out there, from traditional lead-acid to modern lithium-ion, it’s easy to feel overwhelmed. I’m here to break down the key factors you should consider before you buy, so you can spend less time in the garage and more time on the road.
First, let’s talk about battery types. The classic choice is the Absorbent Glass Mat (AGM) battery. These are sealed, maintenance-free, and spill-proof. They handle vibration well, which is crucial for a Harley, and they offer a solid balance of performance and cost. For most riders, a good AGM battery is the default, reliable choice. Then there are Lithium-Ion batteries. These are the new kids on the block. They’re incredibly lightweight—often a third of the weight of an AGM—and they pack a serious punch with higher cranking amps. They also hold a charge much longer when the bike is sitting. The downside is they tend to be more expensive and can sometimes have issues in very cold climates.
Next, you need to get the specs right. The two most important numbers are Cold Cranking Amps (CCA) and Amp-Hour (Ah) rating. CCA is the battery’s ability to start your engine in cold weather. Always match or exceed your motorcycle manufacturer’s recommended CCA. The Ah rating indicates the battery’s capacity, or how long it can provide power. If you’ve added power-hungry accessories like a high-output stereo or extra lights, you might want a slightly higher Ah battery. Finally, physical size is critical. Check your bike’s manual or the old battery for the group size (like BTL14A24A or YTX20L-BS) to ensure a perfect fit in the battery box.
My final piece of advice is to stick with reputable brands that have a proven track record with Harley Davidson motorcycles. A cheap, no-name battery might save you a few bucks upfront, but it could leave you stranded. Investing in a quality battery from a trusted manufacturer is an investment in peace of mind. When you’re looking at the 10 best batteries for Harley Davidson motorcycles, remember that the “best” one is the one that perfectly matches your specific bike model, your riding style, and your local climate.
FAQ
What is the average lifespan of a Harley Davidson battery?
In my experience, a well-maintained AGM battery typically lasts between 3 to 5 years. Lithium-ion batteries can last even longer, often between 5 to 8 years, thanks to their robust chemistry and resistance to sulfation. Your riding habits play a huge role. Frequent short trips that don’t allow the battery to fully recharge, long periods of storage without a tender, and exposure to extreme temperatures can all significantly shorten any battery’s life.
Can I use a car battery in my Harley Davidson motorcycle?
I would strongly advise against this. Car batteries are designed for a completely different purpose. They are physically too large, far too heavy, and are not built to handle the intense vibration of a motorcycle. Using one can damage your bike’s charging system and electrical components. Always use a battery specifically designed for powersports applications to ensure safety and performance.
How often should I put my Harley battery on a tender?
If you aren’t riding your bike for more than two weeks at a time, I recommend connecting it to a smart battery tender or maintainer. This is especially important during the winter months. A tender doesn’t overcharge the battery; it keeps it at an optimal voltage, preventing it from discharging and sulfating, which is the primary cause of battery failure. It’s one of the easiest and most effective things you can do to extend your battery’s life.
Are lithium-ion batteries worth the higher cost for my Harley?
This depends on your priorities. If you’re looking for maximum performance, significant weight reduction, and a longer overall lifespan, then yes, a lithium-ion battery can be a great investment. They provide faster engine cranking and are better for bikes with high-compression engines. However, if you’re on a budget and your bike is a daily rider, a high-quality AGM battery will serve you perfectly well and is a more cost-effective solution for most riders.
What does CCA mean and why is it important?
CCA stands for Cold Cranking Amps. It’s a measurement of the number of amps a battery can deliver at 0°F for 30 seconds while maintaining a voltage of at least 7.2 volts. In simple terms, it tells you the battery’s starting power in cold weather. For a Harley, which has a large engine, having sufficient CCA is non-negotiable. If the CCA is too low, your bike will crank slowly or not at all on a chilly morning. Always check your owner’s manual for the recommended specification when reviewing the 10 best batteries for Harley Davidson motorcycles.
