Universal Sealed Lead Acid UPS/Telecom Batteries

This 12 volt 90 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. This 90 ah size is designed for UPS/Telecom applications, featuring a flame retardant case, and high rate discharge capability. They can also be applicable in industrial equipment, scientific devices, etc. As a backup battery, they are 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. We recommend opportunity charging, for example, in a wheelchair or scooter application, where the batteries are charged each night, or even during the day when not in use, to keep the average depth of discharge above 50%, which helps with longer cycle life.
