Buying Guide – What To Consider When Buying AGM Battery

Different kinds of products are available in the market with different features and functionalities. The AGM batteries have overcome both lead-acid and gel batteries. They are the widely preferred batteries for cars, boats, RVs, and other vehicles. They are known for their durability, fast performance, leak-proof, and shock-proof nature. Before buying a top AGM batteries, certain features and functionalities of the product should be noticed that would define the quality. Those features and the functionalities should match with the pricing and your requirement for a satisfactory shopping experience. If you don’t know how to do all this we are here to help. We have a buying guide solely for you that would help you choose the right product.

1. Compatibility

It’s a truth that the AGM batteries are technically compatible to almost all the vehicles be it marine, car, truck, or other automotive. But then also you should always crosscheck it with your vehicle’s compatibility. You should check whether the specific AGM battery goes well with your vehicle’s engine or not. For this, you can look for the Amperage per hour to ensure that it is not too high. A high amperage battery require a big alternator or more time to recharge. If you don’t regularly use your vehicle than going on with a small alternator and a low amperage per hour would be a better ideal.

2. Cold Cranking Amps

Cold cranking Amps is the CCA the power rating of the battery. It would tell you the ability of the battery to produce current in the cold temperature. The higher the CCA, the better it is to use the battery in winter. The one with higher CCAs are the heavy duty battery that can start the engine regardless of how the low the temperature. Generally speaking, a top-rated AGM battery with around 600CCA is a good choice for cold areas and for extremely cold areas 700-800CCA battery would also do a good job.

3. Reserve Capacity

Reserve capacity is one of the important aspects when purchasing the top car batteries. Basically, it is the number of minutes/hours that a fully charged AGM battery would discharge exactly 25A current until the battery is ineffective. When compared to gel and lead-acid batteries, the AGM battery has a better higher reserve capacity and is more heavy-duty kinds. You can get a reserve capacity of atleast 100 minutes in an AGM battery. This value might change with usage. If you don’t use your vehicle much a smaller reserve capacity would do fin and vice-versa.

4. Durability And Longevity

Both the things are important as it is an expensive investment. You would one that is durable to last for years. Most of the batteries life is proportional to the amount they come in. Even the AGM batteries need to be replaced after 4-6 years of regular use. Most of the top-notch brands AGM batteries last for one to five years. The long life span denotes its heavy-duty construction and a lower discharge rate.

In addition to this, for durability, you should also look for the CCA amount that is the power rating. Most of the heavy-duty batteries have both a larger CCA and long life span.

4. Warranty

Whenever you think of buying a battery for any vehicle or any type, you must consider looking for the warranty period. Usually, they come with 3-5 years warranty period on the manufacturing defects. Having a good warranty period will ensure you have the option to change and repair your product without much concern. These products are a costly investment prefer going for one with a larger warranty period only.

5. Price

While you work for automotive sealed batteries you must keep in mind the price factor. Usually, a good brand with good performance would come in $300more. If you want all the benefits like versatility, compatibility, good reserve capacity, weatherproof, safe, and durable go only with the top notch ones.

However, cheaper ones aren’t bad at all. Going for a product that has all the specifications within your budget is the main consideration. We have made sure to include all kinds of products. It will make it easier for you to choose then. We have a list of options in different price ranges choose the one fitting your budget.
