4 Things To Consider Before Buying A Battery For High Compression Harley:
What this will do is sure you will know about it and not get caught later. It’s a fact that qualitative research is beneficial for anything that matters to you or makes it your next conversation. It depends on the truth. Be conscious of the issues to consider.
1. Size And Depth:
Every vehicle battery has different sizes and shapes. Each of them is made for different purposes. It varies depending on suitable models and their use. Some updated motorcycles use smaller batteries for more space and better weight distribution.
You need to look at the important factors mentioned here. More on this, check the size of your motorcycle battery. However, you can find it in the manufacturer’s guidelines. Installing the wrong size battery will cause unexpected problems, so be careful with it.
On the other hand, you can also use a smaller battery if that is the only option. What you can do is add some extra stuff to fill in the gaps between them. This will work perfectly.
2. Cold-Cranking Amps:
Cold-Cranking Amps, short for CCA, is a measure of how well a cold engine starts. By now, you know that Harleys are not built for speed or heavy riding, intended for racing or the like. Accordingly, you need to look at the CCA that your motorcycle is capable of.
Motorcycles are not all the same either. You may find similar-looking bikes that are not what you think. Of course, they are made to be ridden. The more CCA, the more powerful the battery. For example, if it’s 300 CCA, that means there are 300 amps in it.
If you know well about batteries, then you must know their importance. Although, not only is polarity or batteries, it is really important in any electric-related device. Anywhere, the electron is present, knowing about polarity is a must.
Now, you might be questioning yourself, what is polarity? Well, in basic terms it is the negative and positive terminals of any electrically flowed device.
All batteries consist of a negative and positive end. This is also present in the motorcycle batteries too. All batteries don’t have the same polarity range or output. After all, polarity is essential to check.
Voltage is another hugely important factor to consider. As for high-compression Harleys, it is the most significant thing to look at. In simple terms, depending on the pressure, voltage acts.
To run a high-compressed Harley you need a better voltage supply. Related to that, checking on voltage is indeed a necessity. Another issue to consider is faulty voltage. Faulty voltage can be seen if you are using a really old version of a motorcycle.
Generally, the old Harleys run at 12V, sometimes less than that. Recently, some bikes need much more to run. High-compression systems need better pressure. The better the pressure it will be, the better it will compress.
How Much CCA On Battery Does Your High Compression Harley Need?
Well actually regular Harleys can run on 200 CCA but high-compression Harleys need 300+ CCA. If you ride a heavily compressed Harley I would suggest putting in as much CCA as possible. Because the more power you give it, the easier it starts. Don’t overwhelm her either. It may damage some parts.
First, check the CCA for your vehicle. Next, consider what type of rider you are and what weather conditions you will be driving in. Conditions of weather are a sensitive issue here.
How Long Should A Harley Battery Last?
According to experts, your battery will last much longer than 5 years. On average, people use it for more than 3 years or so. However, if your battery stays good for 3 years or more, you’re good to go. You don’t need to worry about that until it is 5. The batteries that are used are very well built and sufficient to run.
Lithium-Ion, Nano Gel, and AGM batteries last much longer. Besides using a defective damaged battery, you should use a better battery with replacement, it will be expensive but it will be the long-term solution.
When Is The Best Time To Replace A High Compression Harley Battery?
The right time to change any motorcycle battery is between 3.5 to 5 years.
Plus, if your motorcycle struggles to start and you notice the lights dimming in the middle of the road or switches to work properly, you must be concerned about changing its battery.
A battery can be deformed. Deformed batteries should be replaced immediately. Sometimes, these are the times when you will know that this is the right time to change your battery.
The best battery for high-compression Harley depends specifically on you. But among all of them, Antigravity ATX12-HD RE-START Lithium Battery is the best, and MX20L – MOTORCYCLE BATTERY – 500+ CCA is the budget-friendly one. Even though all of them are great to use, these two are more reliable.
Batteries work best when it is handled with care. Also on how you use it and how many years you have had your motorcycle. I hope this article has been a complete guide for you to choose the best battery.
