Best Batteries Harley Davidson

Let us discuss some of the best Harley Davidson batteries available in the market today in detail.

1. Powerstar HD Blue Box Battery

                                                                        Check Price on Amazon

If you’re looking for a direct replacement that’s made exactly for your Harley Davidson, this might be your first stop. This battery is a sealed AGM battery replacement for your Harley Davidson that’s ready to bolt right up.

  • Top or front mount terminals
  • Sealed AGM battery
  • 3-year warranty

I have to admit, I love a 3-year warranty on a battery. There’s nothing more infuriating than mounting up a battery and having it die halfway through riding season. With the PowerStar warranty, you’re covered against a faulty battery for up to 3 years.

If you’re wondering whether or not they’ll fit your model, PowerStar makes several different sizes each intended to fit Harley bikes. You can use the Amazon garage filter to make sure of the fitment before buying.
This is simply hands down the best battery for Harley Davidson.

2. Mighty Max battery


Check Price on Amazon

Another AGM battery is sealed from the factory and ready to mount right up on your bike. Mighty Max makes a huge range of batteries for Harley Davidson battery replacement so there’s a pretty good chance you’ll find the one you’re looking for at an exact match.

  • AGM battery type
  • Optional front or top mount terminal
  • 1-year warranty

While the warranty isn’t as long as the PowerStar batteries, one year is still enough time to be sure the battery is going to perform well for you. If there are any issues, at least you have time to clear them up before the end of the riding season.

Mighty Max keeps their prices quite reasonable and serves up a no-nonsense AGM battery. Remember that AGM batteries can be mounted in any position and are especially good at the high discharge starting loads of a large engine like a Harley.

These batteries run the gamut of sizes. Be sure to follow the link and use the filter to select your year and model of Harley to find the battery that fits your bike. Chances are it will be a perfect size match for an easy swap with your old battery.

Some Of these batteries for specific Harley Davidson models are available in a gel-type battery. Gel batteries may be advantageous in space-constrained applications as they generally run smaller. They are also usually more durable and resilient to hotter climates. The gel batteries are housed in blue cases as opposed to the black case of Mighty Max AGM batteries.

3. Power source lightning star


Check Price on Amazon

PowerSource lightning batteries are designed specifically to be able to dump out the charge you need to start that big bike in any weather. I like that so many makers are producing high CCA AGM batteries that can kick over a Harley without breaking a sweat. PowerSource stays true to that line.

  • Optional front or top mount terminal
  • Factory sealed AGM type battery
  • Available in many sizes to fit your model

These AGM batteries have a unique black and red color that I think stands out a bit. The battery terminals feature a top or front mount option that makes it easy to replace the wires in the exact orientation you found them.

PowerSource makes the batteries specifically to be a direct OEM match. That means you should be able to find one with the exact size, CCA, and Ah rating of your existing battery. If you’re like me this is ideal because there’s something to be said about sticking with a sure thing.

You may pay a bit more for a PowerSource battery compared to other models on our list, but I think their wider selection of direct-fit batteries might make the price worth it.

4. Bike master motorcycle deep cycle gel battery 


Check Price on Amazon

These gel-style batteries are made by bike master that are ready to mount up and replace your Harley battery right now. They’re a little more pricey than other batteries on our list, but they might be worth it in some cases.

  • Ideal for custom or modded bikes
  • Gel-style battery
  • Top or front mount terminals

Gel batteries are exceptionally stable and durable. Like AGM they can be mounted in any orientation. However, these batteries in specific are relatively small for the power they can generate.

For that reason, I think these make a serious contender for a replacement battery on a custom bike. If you’re going to be making a Harley chopper or a mod that requires a small, hidden battery you might look here.

Thanks to the gel-style battery they can be mounted in any orientation so you can hide them up under the tail, tucked sideways in the fame, etc. Get it out of sight!

Overall I think these gel batteries are best suited to hot climates and custom jobs where they make an excellent choice for Harley work.

5. Caltric AGM Battery


Check Price on Amazon

Caltric probably has to compete with PowerSource on our list for the most comprehensive lineup of compatible Harley Davidson replacement batteries. They seem to have a battery that can directly replace just about any OEM battery. It’s insane!

  • AGM type battery
  • Top or front mount terminal
  • Available in tons of sizes

There are two lead-based top or front-mounted terminals ready to replace your old battery. Like the other batteries on our list, I love dual terminal options because you can use the orientation that works easiest for you and avoid a ton of headaches.

1. How Long Should the Harley Battery Last?

Battery Life and Replacement:
While the ultimate life of a motorcycle battery is determined by many factors, according to Harley-Davidson a well-maintained battery should deliver at least five years of service.

2. How Many CCAs Does A Harley Need?

300 CCA

3. What Size Battery Do I Need For My Harley?

All Harley-Davidsons use either a 6-volt or 12-volt battery. If you’re riding a classic that was built before 1965, your Harley most likely uses a 6-volt battery. On the other hand, anything made after that time is going to use a 12-volt battery.

4. Is it OK To Leave A Battery Tender On All The Time?

The answer is yes! Battery maintainers are designed for constant and long-term use. When used correctly, they should be perfectly safe to use as long as you need.
