Expected Life of a Battery in a Gate Motor depends on usage and the brand of Gate Motor But generally needs to be replaced in 3 to 4 years.
Replacement Cost approx $45.00
In case of Power failure normally your gate would open and close around 15 times.
Depends on the Battery fitted.
Some gate motors draw their entire power from the battery which is continually top up with 240V power these gates motors and batteries have a shorter life then others. More modern gate motors only use the battery as a back up in case of power failures.

Parallel Wiring using 3 Batteries in a daisy chain but Still supplying 12 Volts but 3 times stronger then 1 x 12 Volt
Negitive
Postive
This shows a parallel circuit to increase current or power. We are using 12 volt batteries the power of these 3 batteries gives us the power of a battery 3 times as powerful but the voltage stays the same at 12 volts. Parallel wiring increases current but the voltage does not change.
Serial Wiring
This is show you how to use 2 x 12V batteries to get 24V supply to your 24V gate System

Serial Wiring
Series wiring increases voltage but NOT amp/hour capacity.
Parallel Wiring
Parallel wiring increases capacity but NOT voltage.
Important
All the Batteries must be the same type.
