This 12 volt 50 amp hour AGM sealed lead acid battery is the valve-regulated type (sometimes called "sealed" or maintenance-free), which fixes the acid electrolyte in an absorptive fiberglass mat. Most of the sealed batteries under about 30 amp hours are AGM, or absorbed glass mat, even though some people erroneously refer to all the sealed batteries as 'gels'. This 50 ah size is found in industrial equipment, scientific devices, wheelchairs and mobility scooters, etc. They are sometimes only used as a backup battery, constantly float charged, only providing power if the primary power (AC) goes out. In this role they routinely last 5 years, maybe more. In cyclic applications, where they are discharged, the life will be a funtion of the depth of discharge, and the frequency. A routine 100% discharge will give about 250 cycles, whereas a routine 30% discharge will give about 1250 cycles. So keeping lead acid batteries charged whenever possible, extends their life. Using a microprocessor controlled charger is part of this proper battery maintenance, for maximum life.
