This 12 volt 90 amp hour GEL battery is the valve-regulated type (sometimes called "sealed" or maintenance-free), which fixes the acid electrolyte in a gel-like substance. This 90 ah size is usually used in wheelchairs and mobility scooters, etc., or as a backup battery in certain applications. 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 480 cycles, whereas a routine 30% discharge will give about 1800 cycles. In a mobility application with routine deep discharge, a battery may last a year or two. 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.
