Product was a drop-in replacement for battery backup on a swing-gate operator. Let batteries charge overnight, then turned off AC power to gate operator. Gate opened and closed normally several times on battery power only. I didn't try it for more than about 3 open/close cycles but I think the batteries would support many more cycles that that. Based on gate operator power consumption numbers, I think these batteries would support at least 20 open/close cycles and possibly up to 30 open/close cycles. Gate operator is a Doorking 6002. Also, FYI: AutoZone will give you store credit for recycling this type of battery with them.
