Interstate AGM Batteries: Impressive Features

AGM Build

Interstate produces several battery brands and among them are the AGM types. These sealed lead-acid batteries are the best picks at the moment offering the best of everything you could possibly think about.

Absorbed Glass Matt or AGM is a type of sealed lead-acid technology that keeps the electrolyte in a suspended state rather than in a liquid form as with flooded batteries. What you get is a battery that won’t spill at any time since there is no liquid inside. This means you won’t have to check for leaks or the water level of the battery before use which saves you time when it comes to maintenance. This also allows you to place the battery in virtually any position. Whether you’re driving a sedan, SUV or pickup truck, you can mount Interstate batteries in any position you wish thanks to the AGM construction.

Solid Construction

Along with the AGM build, Interstate batteries are built to be solid. They feature a tough exterior designed to withstand the harshness of the weather so that the battery will provide you reliable bursts of power whether in the cold of the winter or the heat of the summer.

Still, on its construction, the exterior of the battery is structured to resist vibration. Vibration occurs when you drive your car and if you don’t know, this isn’t great for your battery. Thanks to the AGM build, interstate batteries will withstand vibrations so they would last you longer than conventional batteries. They will also withstand corrosion and other external elements that would otherwise damage them.

More Power

Another handy perk you get with using Interstate batteries is the power delivery. Not only would you need a battery to deliver high bursts of power to start your vehicle, but you will also need them to maintain it. Also, you would have to consider a battery with a low self-discharge rate.

AGM batteries come with all these beneficial features which are why they last longer than most. Not only will they discharge slowly, but they will also charge faster thanks to their lower internal resistance.

Reliable Warranty

Interstate batteries come with different warranty coverage which depends on how heavily built they are and the type of applications they can be used for.  At its best, you would get a 48-month warranty on an Interstate battery but it could also be as short as 36 months. The best thing is that the warranty comes with a free replacement clause, however, your battery has to meet the warranty requirements.

Some Downsides of Interstate Batteries

Sensitive to Overcharging

This is one of the big issues with AGM batteries that your warranty may not cover. Compared to flooded batteries, AGM batteries have a low tolerance to overcharging and high voltages. This would reduce their lifespan which means you would have to change your battery every now and then if you keep up the habit.

Reduced Capacity Over-time

AGM batteries are championed as the best picks because of their ability to keep a charge for a longer period of time than gel or flooded batteries. However, this perk would vanish with years of use. As you continue to use the battery, its ability to keep a charge for a long period of time gradually diminishes. This problem isn’t found in gel batteries which maintain their excellent performance though they have a shorter lifespan.
