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

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.
