On a good day, your Harley Davidson will start just fine and you can ride the wind with no issues. But are there days when your bike just won’t start. That clunking sound from your engine is just plain annoying, isn’t it? Chances are your battery isn’t living up to the requirements and it’s time to invest in the Best Harley Davidson Battery according to your requirements.

What do you mean by CCA or Cold Cranking Amps?

Widely speaking, CCA is the rating that determines the performance of your battery. Engines need a strong jolt of electricity to get started initially. The battery provides this energy. The CCA rating is the amount of electricity the battery can provide over a standard period of time. The stronger the electricity, the easier your engine starts.

A high CCAis especially recommended for cold climates as the battery has to counter effect the cold while heating up the engine at the initial phase. Same is true for  vehicles at high altitudes. Having extra accessories such as third party headlights and horns can also have a affect on the battery performance. 

Does Higher CCA result in a good condition battery?

Generally, yes.  A higher CCA means stronger starting power hence better performance. But it is not always a good idea to invest in a stronger battery just for CCA. Sometimes it can be an overkill and batteries can be pricey.

The best battery for your Harley Davidson should meet these requirements.

  • It should be able to start the engine without hassle.
  • It should account for the temperature and altitude at your place.
  • It should account for the third party accessories on your vehicle.
  • It should account for the age of your bike as old components such as starters etc. can be harder to work with.

Generally, all vehicles have a CCA rating. Most of the time they are all you need but you can surely customize it based on your needs.    

How to test the CCA of a battery?

In most batteries, CCA is tested as a  measure of the internal resistance of the battery. The battery is put in a simulated environment at sub-zero temperatures  and the discharge time and other readings are taken. They provide an excellent approximation of how the battery will perform in harsh real life conditions. There are regulatory bodies such as the Battery Council International  that make sure the best quality reaches the consumers and that the batteries are robust and safe.

Now that you know what to look for, here are 10 best batteries for Harley Davidson no matter what you’re looking for.
