PumpSpy 12v 75Ah Maintenance-free Sump Pump Battery AGM Ideal for Start-stop Applications, Insusceptible to Vibration, Handles High Electrical Loads

PumpSpy's AGM (Absorbent Glass Mat) Deep Cycle Batteries is compatible with most other battery backup sump pumps and is recommended for use with our PumpSpy Sump Pump Monitoring System. Completely maintenance-free, this sealed battery never requires additional water or acid. The sealed lead acid rechargeable battery can help avoid issues like spillage that can occur with traditional wet-cell batteries. Our AGM batteries do not sulfate or degrade like wet-cell batteries since they are completely sealed. It also differs from wet cell batteries in a way that the electrolyte is held in the glass mats, as opposed to freely flooding the plates. Very thin glass fibers are woven into a mat to increase the surface area that is enough to hold sufficient electrolytes on the cells for their lifetime. This results in higher efficiency during discharging and recharging due to the higher surface area contact between these critical elements. The thermally welded enclosure eliminates leakage, and the battery can be used in any orientation.

• MAINTENANCE FREE - No more frequent maintenance through regular addition of water or acid just to have a proper operation. Our AGM deep cycle battery 12v pack will rescue you from the danger of acid leakage and frequent water refill.
• SEALED LEAD ACID BATTERY - You can now eliminate spilled acid from a tipped battery and hydrogen gas venting because our AGM 12v deep cycle battery is completely sealed, averting any form of leakage.
• BETTER CYCLING PERFORMANCE - Our Absorbent Glass Mat (AGM) Technology enables low internal resistance and high discharge currents. This valve regulated rechargeable battery 12v allows dependable operation in any position.
• FAST CHARGING TIME - Quickly recharge your AGM deep cycle battery 12v up to 5x faster than a standard flooded battery. The improved electrolyte formula ensures stable battery capacity with increased cycle life and vibration resistance.
• CONVENIENT AND FUNCTIONAL - Efficient to use, our AGM battery 12v has an internal compression that limits the shedding of plate material caused by cycling, which also allows a significantly longer life. It is designed for demanding conditions and can handle high electrical loads.
