Key factors to consider when buying Harley-Davidson motorcycle batteries

Engine compatibility

The bigger and more powerful your Harley-Davidson engine, the bigger and more powerful the battery needs to be. The best batteries for Harley-Davidson touring bikes will need to be bigger. This will include the likes of Electra Glide, Road King, Road Glide, Street Glide, and Ultra Classic. The smaller bikes such as the Street 500 and Street 750 won’t need as much starting power.


You should look to have your replacement battery be a 12V battery. 12V is the standard voltage that should be used for full-sized Harley-Davidson bikes. The bikes that are on a smaller scale could get away by using a 6V battery. If you aren’t able to get the required voltage, look at the current battery and use a similar one. By using a battery with incorrect voltage, you could cause the system to malfunction.

Date of expiry

Harley-Davidson batteries are great, but they come with a limited lifespan. They come with an expiration date, and you’ll need to consider their expected life. If you notice that the drum kit sounds weird, the battery’s expiration date might be nearing or be already expired. It would be a smart option to look for batteries that aren’t older than 6 months.

Dimensions of the battery

It is important to consider a Harley-Davidson battery size chart, as bikes contain several mechanical elements in a small space. There is a specific space for the battery.

If you’ve found the battery with the right amount of power, it doesn’t necessarily mean it’ll fit the bike. You must know the dimensions of the battery compartment to ensure that the battery will fit perfectly.

Cold-cranking amps

Cold-cranking amps are the number of amps that your battery can deliver without creating issues if the temperature drops. What this is means is the amount of power that the battery can deliver once you’ve started the engine. If the battery isn’t able to produce enough cold-cranking amps, then you won’t be able to start your Harley-Davidson bike.

Durability and service life

You should consider what type of driving you’ll need to do and the climate you’re residing in. If you’re living in a warmer climate or taking short trips, prefer looking for a battery with a longer lifespan. Small journeys will not give the alternator ample time to recharge your battery. High temperatures will discharge a battery considerably faster as compared to colder temperatures. You can also extend the lifespan of your Harley-Davidson battery by connecting it to a charger when not in use.

Price of the Harley-Davidson batteries

The budget of the Harley-Davidson battery will be crucial when you’re looking to buy replacements. If you buy a battery in the budget section, it’ll cost you under $100. These will help if you have a shortage of money. However, you should be extra careful before you buy a cheap battery. Purchasing from an unreliable brand could end up being a disastrous situation. If you’re looking to buy high-quality OEM batteries, then you’ll need to shell out between $150 and $300. Before you purchase a battery in this price range, remember to check the manufacturing date. Ensure that they’re recent and offer the needed voltage. The brand value will be responsible for the high price.
