Why are Group 35 batteries better than the rest?

You might be wondering whether to shift from the regular battery to Group 35 batteries or not. You might also be considering that the previous batteries cost less than the new ones. However, let me take you through why you should prefer roup 35 battery over the old ones.

Let’s start with the quality. I am sure most of you have had a tough time maintaining your old batteries. Whether it means keeping an eye on them to avoid overcharging, stop the spilling, or topping them off with water. Whatever the case was, it required constant attention.

However, with these batteries, you no longer have to go through this hassle. Most of the group 35 batteries are self-maintaining which means that they are not spillproof, are not damaged due to overcharging, and are 100% maintenance-free.

As far as performance is concerned, these are supreme quality batteries that are effective and work efficiently throughout summers and winters. Not to forget that these batteries are also resistant to vibrations and corrosions.

Did your standard car battery deteriorate over time? Well, not anymore. These new batteries have a higher reserve capacity and run for a longer time. Not only this, but they can also recharge themselves in as less as 4-6 hours.

Yes, these do cost more than the flooded batteries but rest assured you will not have to change these every 3 years like the regular batteries. These batteries can last up to 10 years hence you spend a chunk at the beginning but save money in the long run.

Just like group 35 battery, there is a 24F battery as well. If you are looking for that, check this out. Moreover, now that everything is becoming environmentally friendly, it is possible for us to recycle car batteries as well. To know more about it, read this article.

Important things to consider before buying

1- Size

It is very important to check whether the battery fits your car or not. It is quite possible that a group 35 batteries might not fit under the hood of your car. So before going to purchase the battery, make sure that you check the dimensions of your previous battery.

Measure the size of the new battery and inquire about its power voltage. It is very important for the battery to power the car or else it will be of no use. Also, if the battery is a high-powered one, it might cause electrical issues. Hence, get the one that exactly fits the requirement of your car.

2- Reserve capacity

Let me begin by explaining what reserve capacity is. It is the amount of time (minutes) the battery can sustain a constant load before being fully discharged. Just by the meaning, you might have figured out that this is a very important aspect when it comes to the battery.

You would not want to risk your journey by relying on a battery that has poor reserve capacity. When the car is in use, it does not charge. Therefore, you might end up in trouble if the battery runs out mid-way. However, to avoid falling prey to such a situation, you need to get your hands on a battery that has good reserve capacity. Good reserve capacity means that the battery could work for a longer period of time than usual.

You can go for choices with a little capacity if your car system does not require too many amps. Otherwise, get the one that could take the load.

3- Service Life

This means the number of years your battery will work. If you are buying a group 35 battery, you are surely spending a large amount of money. That is why you need to make sure that the battery offers a long warranty and serves for longer years. You should look for options that would last for at least a decade or so.

4- Cold Cranking Amps

This is a rating that is used a lot in the battery industry to show that the battery has the ability to start and run an engine in cold temperatures. This is most commonly used as CCA. Without a doubt, this is the most important feature in a car.

Without a good CCA, you might be stuck on the road if the weather gets harsh. For cars, the CCA rating ranges from 350 to 600 amps. However, this will be higher for trucks.
