The 12V 7Ah battery used in Econo / Marantec-type operators is a very common, well-defined product:

 It’s a 12V 7Ah sealed lead-acid (SLA / VRLA) battery used for backup power in gate motors, doors, alarms, etc.

 Important:
All of these are functionally interchangeable as long as:

• Voltage = 12V
• Capacity = 7Ah
• Terminal type matches
