This battery is used with GTO model's PRO2500/PRO3000/PRO4000 swing gate operators, SL1000/SL2000 slide gate operators, and Mighty Mule 500/502 operators. It works also with the discontinued PRO1000, PRO2000, and PRO1800 (PRO1800 requires another 6 VDC battery below, see BATT06).

This is the standard 12 volt, 7.0 amp-hour, maintenance-free battery and is  the only battery approved for use with GTO/PRO operators. Life expectancy is 3 to 5 years.
