Whether you’re replacing an old battery or looking for a new one, this guide will walk you through everything you need to know about Super Start AGM batteries. I’ll cover all the key features, specs, and factors to consider before you make your purchase.

Let’s dive in!

Key Features of Super Start AGM Batteries

AGM, or absorbed glass mat, batteries like the Super Start have a few advantages over standard wet lead acid batteries. For one, the electrolyte in an AGM battery is suspended in close-knit glass mats, which makes these batteries spill-proof. This allows them to be safely mounted in any position without leaking.

AGM batteries also have extremely low internal resistance, which allows them to deliver high currents on demand. This gives them enormous power for starting engines and supplying accessories.

Finally, AGM batteries are much more resistant to vibration and shocks. Their stiff plates and sealed design allow them to handle bumps and jostling without damage. This makes them ideal for vehicles and marine applications where movement is frequent.

Specific to the Super Start line, these AGM batteries feature:

• Pure virgin lead plates for maximum performance and life
• Advanced spill-proof design that can be mounted upright or on its side
• Significantly lower self-discharge rate, allowing for longer storage times
• Full 1-year free replacement warranty for peace of mind

So in summary, you can expect a combination of robust power delivery, durability, and longevity from a quality AGM battery like the Super Start.

How Long Do Super Start AGM Batteries Last?

The average lifespan of an AGM battery like the Super Start is 3-5 years. However, there are several variables that determine actual battery life:

• Climate: Heat is the enemy of batteries. Colder temperatures allow for longer life.
• Maintenance: Proper maintenance like routine charging extends life. Lack of maintenance shortens it.
• Application: Deep cycle and frequent discharge/recharge cycles wear down batteries quicker. Light-duty starting uses preserve life.
• Charging: Trickle charging is ideal. Overcharging damages plates and mats. Undercharging leads to sulfation buildup.
• Quality: Premium AGM batteries like Super Start simply use higher grade materials that endure more.

With proper care and maintenance, a Super Start battery that’s lightly used (like in a stored RV) could potentially last over 5 years. But a heavily used battery in a hot climate may only last 2-3 years. Checking your usage and conditions can help estimate realistic lifespan.
