Sealed Agm Batteries

More Info on Sealed AGM Deep Cycle Batteries

AGM's typically have less than a 2% self discharge rate during transport and storage. Because they are fully sealed, they can be transported easily and safely by air, can be mounted on their side or end, and are extremely vibration resistant. AGM's come in most popular battery sizes and are even available in large 2-volt cells for the ultimate in low-maintenance large system storage.

Because of their high cost when first introduced to the market, AGM batteries were mostly used in commercial installations where maintenance was either impossible or more expensive than the price of the batteries. Now that the cost is coming down, they are seeing use in all types of solar systems - clearly some of today's owners feel the advantages of AGM deep cycle batteries outweigh the price difference and maintenance requirements of flooded lead acid batteries.

AGM Deep Cycle Battery Features

• Grids are made from a heavy-duty alloy that is resistant to corrosion
• The high-density positive active material supports structure during the deep cycling process
• The carbon-enhanced negative active material boosts cycling performance and charge acceptance
• The expertly engineered glass mat separators help inhibit internal shorts and acid stratification
• The low self-discharge rates allow for longer storage periods without requiring you to boost the charge repeatedly

Benefits of Sealed AGM Deep Cycle Batteries

Because sealed AGM solar batteries are completely sealed, they:

• Can't be spilled
• Do not need periodic watering
• Emit no corrosive fumes
• Use an electrolyte that will not stratify

How Do AGM Solar Batteries Work?

The defining characteristic of an AGM solar battery is the thin, ultra-fine fiberglass mat that is placed in between the plates. Proper engineering ensures that the mat and plates are packed tightly, minimizing the possibility and effects of vibration.

Originally, engineers developed AGM technology for use with military aircraft, so efficiency was essential - and now, you can benefit from this precision-level engineering.

When to Use AGM Batteries

Depending on your preferences, budget, long-term goals, and solar setup, you can determine whether AGM batteries are the right option. An AGM solar battery is an ideal choice in scenarios such as:

• Poorly-ventilated areas where fumes and/or hydrogen cannot be permitted
• Setups where fumes could result in corrosion to electronics (such as cell phone sites)
• When shock- and vibration-resistance is crucial
• When spilled acid (for example from broken, leaking, or tipped batteries) cannot be allowed
• When maintenance is challenging and/or expensive (often due to the location of installation)
• When in an area where batteries may be subject to freezing (40°F and lower)
• Any setup that requires a reliable, fully sealed battery for environmental and/or safety reasons (inside an RV, an enclosed space on a boat, wheelchairs, etc.)
