All controls should be equipped with sufficient battery
standby to operate the system for the maximum duration of outages you are likely to
experience in your area. Do remember that the chargeable battery deteriorates with time.
The life of a chargeable battery is normally half after one year of usage and requires
replacement after 18 months. The amount of batteries needed depends upon the type and
amount of devices used and how long you want the system to function without normal
electrical power. |
